Overview

The Hoffman E2PBXM is an extra-deep pushbutton enclosure constructed from mild steel with a polyester powder painted finish in ANSI 61 gray. It features continuously welded and ground smooth seams for durability. The unit includes a captivated cover and is designed to accommodate 30.5-mm and 22.5-mm pushbuttons and switches. It provides Type 12 and Type 13 indoor protection against dust, dripping non-corrosive liquids, and oil. The enclosure measures 7 inches in width, 4.22 inches in height, and 4.75 inches in depth.

Feature Summary

• Designed specifically to hold 22.5 mm and 30.5 mm pushbuttons and switches
• Constructed from mild steel with a polyester powder painted finish
• Features continuously welded and ground smooth seams
• Includes a captivated cover for secure operation

Applications

• Industrial control stations requiring operator installation
• Indoor environments needing protection against dust and oil
• Applications involving 22.5 mm pilot lights and switches
• Control panels requiring Type 12 rated enclosures

Procurement Notes

Verify that the specific application requires the extra-deep profile, as standard depths may suffice for some installations. Confirm that the required operators fit the precut openings for 22.5 mm components. Note that the back panel is not included with this enclosure; ensure separate procurement if mounting hardware is needed. Check for compliance with UL 508A and CUL standards relevant to your regional electrical codes.

Selection Notes

Select this model when additional depth is necessary to accommodate larger switches or multiple operator layers. The Type 12 rating makes it suitable for dirty or damp indoor locations where oil and dust are present. Ensure the 7-inch by 4.22-inch footprint fits within the available panel space. Consider the weight and mounting requirements of the installed operators to ensure structural integrity.

Part Context

This component belongs to the Hoffman E series of extra-deep pushbutton enclosures. These units are part of a broader family of industrial control station housings designed for harsh indoor environments. The E2PBXM variant specifically addresses the need for deeper chambers to house complex switch assemblies without protruding excessively into the control cabinet.

Replacement Considerations

Direct substitutes include other Type 12 extra-deep pushbutton enclosures from nVent Hoffman with identical dimensions and hole patterns. Verify compatibility with existing 22.5 mm operators before swapping brands. Alternative models may offer different materials or finishes but must match the dimensional constraints.
