Enclosure Banner

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. Read More…

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.

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.
