Round Enclosures

Protect keypads, push-buttons, and other handheld controls with these round enclosures that are more comfortable to hold than square enclosures. A recess in the lid allows a membrane keypad to sit flush with the lid for a finished look. All of these enclosures are rated IP66, so they protect contents in damp, dusty, and washdown areas. Made of polycarbonate plastic, they won’t break down when exposed to UV rays.

Internal mounting bosses allow you to mount panels, circuit boards, and components without drilling holes in the enclosures. Mounting screws use different holes than the lid screws, so you can mount these enclosures on a wall or surface after the lid is sealed. This means you can assemble components in the shop and then mount the enclosures on-site.
