Industrial pushbutton enclosure

The Hoffman VM433-PBS1 is a single-hole enclosure built for 30 mm pushbuttons in industrial electrical control panels. Its polyester body carries a NEMA 4X rating for corrosion and wash-down resistance. The grey housing measures 4.02 in high by 2.84 in wide by 3.31 in deep with no conduit entrance holes provided. Cover corner screws are included for secure closure.

30 mm single-hole cutout

The decisive specification is the 30 mm hole diameter, which matches standard industrial pushbutton operators. The enclosure provides exactly one mounting position in a single column layout. Builders needing multiple operators or a different cutout size must select another enclosure. No conduit knockouts are present, so cable entry must be drilled on site.

Sustained wash-down and UV exposure

Polyester construction resists prolonged chemical splash, high-pressure cleaning and outdoor UV exposure without degrading. The NEMA 4X seal maintains ingress protection during continuous wet or dusty operation. CSA C22.2 No. 94 and UL 508A listings confirm compliance for long-term industrial service. The enclosure is restricted from sale in certain states.

What do the UL 508A and CSA C22.2 No. 94 listings cap in practice?

They certify the enclosure for use in industrial control panels per UL 508A and confirm it meets CSA C22.2 No. 94 requirements for polyester enclosures.

How do I mount this 4.02 in by 2.84 in enclosure?

The polycarbonate body has integral mounting flanges; secure it with screws through the flange holes to a flat panel or machine frame.
