Industrial Control Housing
This Hoffman pushbutton enclosure provides a NEMA 12 and IP65 rated housing for up to four 30.5mm oil-tight operators. The mild steel body finished in ANSI 61 gray polyester powder suits indoor industrial environments where protection against dust, dirt and non-corrosive dripping liquids is required. It accepts all standard brands of 30.55mm push buttons, switches and pilot lights. Builders needing more than four operator stations or a different NEMA rating should select another enclosure.
Straightforward Panel Mounting
The enclosure measures 10.00 inches high, 3.25 inches wide and 2.75 inches deep with a single column of four 30.5mm holes. External mounting feet allow direct surface installation without accessing the interior. Captive cover screws stay with the lid during maintenance, and a closed-cell oil-resistant gasket seals the joint when the cover is refastened. A grounding stud is provided for electrical continuity. Installers must supply their own operators and wire the devices themselves.
Durable Seal Under Continuous Exposure
The polyester powder coating and closed-cell gasket maintain their protective qualities during prolonged exposure to splashing water, coolant mist and airborne particulates typical of factory floors. UL Type 12, 13 and CSA listings confirm the enclosure meets sustained ingress and mechanical strength tests rather than only brief splash resistance. The captive screws resist vibration loosening over long service periods. The steel construction does not degrade under UV light, but the enclosure is not rated for prolonged direct outdoor weathering.

Questions about this item
How can I confirm the enclosure is properly sealed after installing the pushbuttons?
Tighten the captive cover screws until the closed-cell oil-resistant gasket compresses evenly around the perimeter, then verify the IP65 and NEMA 12 ratings by checking for no dust or water ingress during a hose test.
What components are included and what must I supply separately?
The enclosure ships with the mild-steel body, ANSI 61 gray polyester powder finish, external mounting feet, captive cover screws, closed-cell oil-resistant gasket, and grounding stud; you must provide the 30.55 mm oil-tight pushbuttons, switches, or pilot lights.
Which hole configuration matches my four-device layout?
This model has a single column with four 30.5 mm holes spaced for standard 30.55 mm oil-tight operators, so it fits exactly four devices in a vertical row.
