Enclosures

Aluminum Corrosion-Resistant Washdown Enclosures

Aluminum enclosures are a lightweight yet durable alternative to stainless steel.

Heavy Duty Aluminum Corrosion-Resistant
Washdown Enclosures

These enclosures have thicker walls than standard aluminum enclosures, but are still a lightweight yet durable alternative to stainless steel.

Circuit Board Enclosures

These enclosures have internal slots to hold circuit boards in place.

Build-Your-Own Circuit Board Enclosure Bodies

Choose a body and two matching end caps to make your own dust-tight or watertight enclosure.

Heat-Dissipating Circuit Board Enclosures

With internal slots and external fins, these enclosures hold circuit boards securely and dissipate heat to keep electronics from overheating.

Aluminum Submersible Enclosures

Lighter than stainless steel yet durable, these aluminum enclosures protect electronics from frequent washdowns and withstand periodic submersion in water.

Machine-Mount Aluminum Submersible Enclosures

Attach these enclosures to machine control panels or walls to guard electronics within the enclosures from water in wet and washdown areas. You can mount them without removing the cover and exposing electronics, such as sensors, switches, and circuit boards, to the environment.

Aluminum Weather-Resistant Enclosures

Made of aluminum, these enclosures resist corrosion from rain, sleet, and snow. While not as corrosion resistant as stainless steel, aluminum is lighter for better mobility, and also easier to machine for custom mounting.

Weather-Resistant Enclosures with Cooling Fans

Fans built in to these enclosures keep electronics at the temperature you set, and the filtered intake and exhaust let cool air flow through the enclosure without letting water and contaminants in.

Hazardous Location Enclosures

For use in hazardous locations, these enclosures are rated NEMA 7 and 9 and meet UL Class I, Divisions 1 and 2, Groups B, C, and D; Class II, Divisions 1 and 2, Groups E, F, and G; and Class III, Divisions 1 and 2.

Push-Button Hazardous Location Enclosures

Protect electronics in dirty and wet areas that also contain combustible gases and dust. All of these enclosures have standard push-button holes, so you don’t need to measure and cut the holes yourself.

EMI/RFI-Shielded Enclosures

These enclosures reduce electromagnetic interference (EMI) and radio frequency interference (RFI), which can cause electrical problems like flickering monitors, interrupted data signals, and unwanted radio noise.
