Industry Information

Electronic Enclosures

Electronic enclosures house a wide range of electronic equipment to protect them from damage, contaminants and interference. They are a standard component in most industrial and manufacturing settings because of the sensitive and important nature of electrical systems and wiring. Electronic enclosures are generally made of sheet metal, like stainless steel or aluminum, although fiberglass, high strength polymer plastics and other composites are also used.

Electronic enclosures range in size from one square inch that fits a simple pushbutton assemblage to an entire room that contains large computer networks and wiring. Electronic enclosures are frequently rectangular and box-like; other styles are round or have sloping sides. Lids, removable panels, access points and vents are necessary in some applications, and recessed tops accommodate labels and keypads. Enclosures for handheld devices can have soft ergonomic grips and a battery door. Many enclosures simply snap together, although a tight seal to keep out dust and water is available using lap joint or tongue and groove construction. Not only do electronic enclosures protect their contents from pollutants or moisture, they also shield the internal equipment from electromagnetic interference, or EMI, that would disrupt the efficient performance of the circuitry inside the enclosure. Sometimes referred to as electrical cabinets, electronic enclosures are widely used in the medical, automotive and agricultural industries to protect equipment and instruments but can be found in any electronic application. Electrical enclosures can be custom made for a precise fit although there are already thousands of enclosure designs. Factors to consider when selecting an appropriate enclosure include size, construction materials, mounting, security and NEMA type, which refers to the grading assigned by the National Electrical Manufacturers Association.

Metals have traditionally been the electronic enclosure material of choice until the recent developments in plastics and composite materials. Aluminum enclosures are good thermal and electrical conductors. Though tough, aluminum is also malleable and very lightweight, especially when rolled into sheets. Stainless steel enclosures are also durable and corrosion resistant, having properties similar to aluminum. Many computer enclosures are made of aluminum or steel. Although electromagnetic interference can travel through these metals, they can be coated with a substance to screen their contents from the rays. For smaller and more complicated enclosures, moldable polycarbonate plastics are used. One similar material is acrylonitrile butadiene styrene, a common thermoplastic called ABS. Its superior electrical insulation properties and impact resistance make it a popular choice for electrical enclosures. Because it is lightweight and shock absorbent, ABS is used for pocket and handheld enclosures that will be handled frequently. Other types of enclosures include protective, desktop and mounted styles. Enclosures can be mounted by screws or fasteners that fit through the designated holes in the back or bottom of the housing.

Electrical enclosures are boxes that protect electronic equipment such as conduits, connections and switches from the environment and from tampering. They are found in public places such as street corners or parks as well as in buildings and residences. These rectangular enclosures are typically made from plastic or metal, particularly steel and aluminum, in order to resist corrosion and shelter their contents from weather and vandalism. Electrical cabinets can be horizontally or vertically oriented and usually bear a warning to alert those nearby to the sensitive and potentially dangerous equipment inside. They may also be locked. Some cabinets are mounted. Standardized rack mount enclosures accommodate multiple equipment modules that are 19 inches wide. Protruding edges allow the module to be fastened to the frame, which is usually steel or aluminum because of their strength and load-bearing properties. Professional audio equipment, computer servers and other electronics are stored inside the rack mount enclosure, and many models have a door that can be shut and locked. Depending on the application, the enclosure may use thicker metal for the frame and be encased in reinforced plastic, carbon fiber or Kevlar. Instrument enclosures can also be rugged; some are designed specifically for use in demanding situations where explosions, earthquakes or tornadoes may occur. These enclosures are often made from die cast iron or aluminum and range from small rectangular metal boxes to circular enclosures that can protect head-mount style instruments.

NEMA enclosures are certified by the National Electronic Manufacturers Association depending on the type of application for which they are used. They range from Type 1 to 13 and identify whether the enclosure is intended for indoor or outdoor use, in non-hazardous or dangerous situations and what it can protect from. Type 1, for example, is for general indoor use to prevent accidental contact with the enclosed equipment. Type 4X can be used indoors or outdoors and protects against corrosion, windblown dust and rain, sleet, snow, splashing or hose-directed water and the formation of ice on the enclosure. NEMA Type 12 is for industrial use indoors to protect from lint, dust, dirt, fibers, dripping, seepage and dripping non-corrosive liquids. The enclosure may not have any knockouts (partially punched holes) or openings except for oil and dust-tight mechanisms or gaskets. Hinged doors must require a tool to open and have an external means for mounting. By certifying enclosures, NEMA helps manufacturers and distributors get exactly what they need and ensures that the electronics inside will be able to function properly and safely.

Factors to Consider when Buying Electronic Enclosures

Given the types of electronic enclosures available on the market, buying one that has all the features you require can be a daunting task. To make the task easier, the best practice is to list out the features that are required; and based on your requirements; decide between a plastic enclosure, polycarbonate enclosure or metal box.

The features that you need to look for in electrical enclosures are: impact shock shielding, static shielding, magnetic shielding, dirt and dust proofing, and heat shielding. Here we will discuss why all these features matter and what their purposes include.

  1. Impact Shielding
  2. Pieces of modern electronic equipment, unlike their bulky predecessors, are to some degree fragile and can lose efficiency after being exposed to physical impact. Therefore, any electrical enclosure that you install needs to have impact shock shielding, which protects or minimizes the implication of physical impact and vibration to the equipment housed in the enclosure.

  3. Static Shielding
  4. Some electric components can be damaged by static current; therefore, static shielding from external sources is an important attribute an enclosure must offer. Moreover, unexpected or abrupt electrical surges are damaging, especially to dormant parts. The chosen enclosure must provide appropriate grounding to withstand surges and keep components safe from the charge interferences.

  5. Heat Shielding
  6. When electricity passes through electrical components, heat dissipates invariably. Most electronic equipment, however, is heat sensitive, thus need shielding to work efficiently. Therefore, an enclosure should provide heat shielding. Some enclosures have in-built heat sinks, which do not allow temperature built up inside the enclosure and push the heat outside. However, heat sinks are normally used and are installed only when there is a special requirement.

  7. Dirt and Waterproofing
  8. Some electronic enclosures are dirt resistant, while some provide absolute proofing, even from windblown dirt. Similarly, some models offer water-resistant properties, whereas some are resistant even to ice. Almost all electrical components need protection from dirt and water, so it's best to determine your unique requirements before assessing their effectiveness in this area.

  9. Magnetic Shielding
  10. Similarly, like static current, electro-magnetic pulses are damaging to electronic components. Therefore, an enclosure should provide adequate protection against pulses. Although electro-magnetic bursts are very uncommon, expensive components especially should be housed in an enclosure that provides enough magnetic shielding.

There many considerations to ponder when selecting an electronic enclosure. Some enclosures are manufactured primarily for storing and transporting electronic equipment. Similarly, there are enclosures especially for computer equipment, like processors and hardware. The third type of enclosures is made for car electronics, which house and hold car electronics. The main purpose of these types of enclosures is to provide resistance to impact, heat and dirt, which are inherent to vehicles. Moreover, custom enclosures are also available, which are designed and fabricated based on a manufacturer's unique business requirements.

Which Material is the Best for Electronic Enclosures?

With ongoing advancement of fabrication technologies, electronic enclosures are increasingly manufactured from a wide variety of materials from fiberglass to polycarbonate and metal. Each building material provides its own advantages. However, with the large numbers of options available, it has also become difficult to decide the right material for an enclosure. Therefore, the following paragraphs offer advice on selecting the most appropriate material for electrical enclosures.

  • Thermal Insulating and Transferring Capabilities
  • Heat release occurs as electric current flows from electrical components. There is nothing you can do to stop this release completely. Therefore, it is important that an enclosure insulates heat dissipated by the electrical equipment it houses. Thermal insulating capability probably is the most important factor while deciding the material for enclosures that holds sensitive components. Plastics boxes, such as polycarbonate enclosures, are considered the favored material when heat interference needs to be reduced, especially when the exterior temperature is low and components need protection from this low temperature. However, when electrical components generate too much energy and require heat transfer, then metal boxes made from stainless steel are better suited. Some electrical cabinets are configured with ventilation fans to offer constant operating temperatures.

  • Installation Location

    If an enclosure is installed at a mine, electrical enclosures should be made from a material that is explosion proof. Similarly, if an enclosure is located outdoors, fiberglass is considered a preferred material; however, extended exposure to high or low temperatures can warp the fibers in the material. Therefore, other available polycarbonate alternatives should be used. For indoor use, where exposure to moisture can be reduced, aluminum enclosures are considered better materials.

  • Durability
  • Durability is by far the most important consideration, as no one wants to invest in new enclosures repeatedly over time. The durability of an enclosure, however, is determined by the installation location, as plastic enclosures can be deemed durable when not exposed to extreme environmental conditions. The common rule is, if you need enclosure for outdoors, always select sheet metal fabrication options, when durability is the only factor.

  • Visual Appeal
  • Enclosures sometimes can look incongruous with their environments, rendering related aesthetic efforts useless. Therefore, always consider the aesthetics of an enclosure material, especially when it is installed in an open space and interferes with design efforts.

  • Price
  • For many manufacturers, price is the ultimate determinant un an enclosure decision. However, if price is the only determining factor, the selected enclosure can only provide additional headaches. Enclosures made from materials like fiberglass, plastics or lower-grade stainless steel, can save money upfront. However, over time, their performance may become a concern. Therefore, always make cost a contributing factor, but not the sole factor.

Other than the considerations described above, you also need to consider control of liquid water movement, control of heat flow, strength and rigidity, control of water vapor flow, and control of air flow. All these mentioned factors can help you to make a decision that best addresses your manufacturing needs. You may wish to seek the advice of your engineers or suppliers before making the final decision on an electronic enclosure.

Electronic Enclosure Types

  • Aluminum enclosures house and protect electronic instruments or equipment from damage or interference. Because these enclosures can be used indoors and outdoors, they must protect their contents from a variety of weather conditions as well as from dust and dirt.
  • Computer enclosures are housings made specifically for computers. Computer enclosures are usually made of metal and are used to protect the inner electronics from dust and moisture damage.
  • Custom enclosures are made to the detailed specifications of the customer. The sizes can vary to enclose a range of equipment, from a fuse box to a number of electronic devices and cables housed in a separate room, referred to as network racks.
  • Double-shielded enclosures have an inner wall that is isolated from the outer wall with the exception of the region where the power-line filters and coaxial connectors penetrate. Double shielded enclosures can also be rooms.
  • Electrical cabinets are filters designed to protect electronic parts from damage caused by dirt, oil, dust and moisture. These cabinets, used in virtually every industry, give electronic components a plane of operation that improves their efficiency.
  • Electrical enclosures house electronic equipment and instruments from unintentional contact, contaminants and interference. The contents of these enclosures are often sensitive components of electrical circuits and need to be protected from dust, dirt, water and other liquids. Accidental contact could cause bodily harm and damage the equipment itself.
  • EMI shielding involves using materials, such as filters, gaskets and coatings to block, absorb or redirect electromagnetic waves, in order to prevent electromagnetic interference (EMI) from harming sensitive equipment. These materials are attached to the metal surface of such enclosures.
  • Instrument enclosures protect electronic devices inside a metal or plastic housing. Because of their sensitive circuitry, the components must be protected from dirt, water and accidental contact. Being kept in an enclosure prevents the intrusion of solid foreign objects as well as liquids to a certain extent.
  • Junction boxes are a type of enclosure used specifically for wiring and the connecting of wiring to a larger unit and are often constructed with metal material. Junction boxes must have a cover plate and should be easily accessible.
  • Metal boxes are metal enclosures that protect electronics.
  • Metal enclosures are typically made of either aluminum or sheet metal. Metal enclosures are being replaced by enclosures made of lighter, more durable composites.
  • NEMA enclosures are a specific type of electronic enclosure that is certified by the National Electronic Manufacturers Association (NEMA), which rates the enclosures bases on the type of application for which they are used. NEMA enclosures are typically made from carbon or stainless steel and can range in size from a pushbutton panel to a room-sized panel.
  • Plastic enclosures are plastic housings that protect electronics.
  • Pushbutton enclosures are either rectangular or wedge-shaped. Pushbutton enclosures have cutouts for surrounding and securing pushbuttons and can be mounted to a wall, pedestal or suspension system.
  • Rack mount enclosures have standardized frames and racks for mounting multiple electronic equipment modules. Vertically stacked equipment saves floor space and is easier to maintain. The enclosures and modules are 19 inches wide, and the height is measured in multiples of 1.75 inches each called one rack unit (U).
  • Stainless steel enclosures protect electronic equipment and instruments from damage due to interference, contaminants or accidental contact. Because of its corrosion resistance and lightweight strength, stainless steel is a popular material choice for enclosures, especially those that will be used in the food and beverage industry or in an setting with harsh chemicals.
  • Terminal boxes are similar to junction boxes and are used for the housing and protection of a connection point between two different types of wire.
