E20PBY25M

Overview

The Hoffman E20PBY25M is an extra-large pushbutton enclosure constructed from steel with a polyester powder-coated finish over a phosphatized surface. It features a RAL 7035 light gray color and continuous hinged cover design. The unit is rated NEMA Type 12, providing protection against dust, dripping non-corrosive liquids, and oil. It includes 20 pre-drilled holes for 22.5mm pushbuttons or switches, arranged with a 64mm center-to-center spacing. Seams are continuously welded and ground smooth, while captive screws thread into sealed threads to maintain environmental integrity.

Feature Summary

• Continuous hinged cover with captive screws for secure access
• Welded and ground smooth seams for enhanced durability
• Pre-drilled panel layout optimized for standard pushbutton installation

Applications

• Industrial control panels requiring NEMA 12 protection
• Machine tool interfaces with multiple operator inputs
• Automated manufacturing equipment housing
• Process control stations in factory environments

Procurement Notes

Verify the specific hole diameter compatibility (22.5mm vs 30.5mm) against your switch requirements before ordering. Confirm that the NEMA 12 rating meets your facility's environmental standards regarding oil and dust exposure. Ensure the enclosure dimensions fit within your designated panel space constraints.

Selection Notes

Select this model when a high-density pushbutton interface is required within a single enclosure. The extra-large format supports up to twenty 22.5mm devices. Consider the continuous hinge for applications where frequent access is needed without removing fasteners entirely. Verify mounting orientation and available panel depth for cable routing.

Part Context

This component belongs to the Hoffman Extra-Large Pushbutton Enclosure series. It is designed as a ready-to-populate solution for industrial automation. The product line emphasizes ease of integration through pre-drilled layouts and robust steel construction. It serves as a standardized housing for operator interface components in heavy-duty settings.

Replacement Considerations

Check for updated nVent Hoffman part numbers if discontinuation occurs. Ensure substitute models maintain the same 20-hole configuration and 22.5mm hole diameter. Verify that alternative enclosures offer equivalent NEMA 12 ratings and similar physical dimensions for direct replacement.
