E10PB

Overview

The Hoffman Enclosures Inc. E10PB is a steel pushbutton enclosure designed for indoor industrial applications. It features a Type 12 and Type 13 rating, providing protection against dust, falling dirt, light splashing water, and oil non-corrosive environments. The unit measures 24.75 inches in length, 3.25 inches in width, and 2.75 inches in depth. It includes ten pre-cut holes sized for 30.5-mm or 22.5-mm pushbuttons and switches. The enclosure is constructed from steel with a polyester powder painted finish in ANSI 61 gray.

Feature Summary

• Pre-cut design accommodates standard 30.5-mm or 22.5-mm pushbuttons and switches
• Seams are continuously welded and ground smooth for structural integrity
• Cover screws are captivated and thread into sealed wells to maintain ingress protection
• Includes bonding provision on the cover and a grounding stud on the body

Applications

• Housing pushbuttons and indicator lights in industrial control panels
• Enclosing momentary and maintained switches in machinery control stations
• Protection of operator interface components in environments with oil and non-corrosive contaminants

Procurement Notes

Verify that the specific order does not include a back panel, as the E10PB typically ships without one. Confirm hole size compatibility (30.5 mm vs. 22.5 mm) matches the intended switch hardware. Ensure the application environment aligns with Type 12/13 ratings, excluding exposure to hose-down conditions or corrosive chemicals. Check for UL 508A and CUL listing requirements if applicable to the final assembly.

Selection Notes

Select this model when a compact, pre-drilled housing is required for multiple pushbuttons in a single unit. The 30.5 mm hole spacing is standard for many industrial controls. Consider the internal volume constraints relative to the depth of the selected switches. Verify that the steel construction and gray finish meet aesthetic and corrosion resistance needs for the installation site.

Part Context

This component belongs to the Hoffman pushbutton enclosure family, specifically engineered for modular control station integration. It serves as a protective housing rather than a complete control station, requiring separate purchase of switches and potentially mounting hardware. It is commonly used in manufacturing automation and process control systems where operator input devices need environmental shielding.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. Alternative solutions may involve custom fabrication or selecting different series enclosures with compatible dimensions and hole patterns. Verify dimensional overlap before substituting.
