E5PB

Overview

The Hoffman Enclosures E5PB is a steel pushbutton enclosure designed for industrial control applications. It features a gray polyester powder-coated finish and measures 12.50 inches in height, 3.25 inches in width, and 2.75 inches in depth. The unit includes five holes spaced at 30.5 mm centers to accommodate standard push buttons and switches. It provides Type 12 protection against dust, dripping non-corrosive liquids, and sleet. The enclosure is constructed from carbon steel and includes captive cover screws for secure mounting.

Feature Summary

• Designed specifically to house 30.5 mm and 22.5 mm push buttons and switches
• Provides NEMA Type 12 protection against environmental contaminants
• Constructed from durable carbon steel with a corrosion-resistant powder coat finish
• Includes captive cover screws to prevent loss during maintenance

Applications

• Industrial machine control panels requiring push button integration
• Factory automation systems needing protected switch enclosures
• Process control stations operating in dusty or wet environments

Procurement Notes

Verify that the required push buttons match the 30.5 mm hole spacing specification. Confirm that the installation environment meets Type 12 requirements, as this enclosure is not rated for washdown or submersion. Ensure adequate clearance for the 2.75-inch depth when integrating into existing panel layouts. Check for any specific grounding requirements if connecting to sensitive electronic equipment.

Selection Notes

Select this model when a compact, pre-drilled solution for multiple push buttons is needed. It is suitable for indoor or sheltered outdoor use where Type 12 protection is sufficient. Consider alternative models if higher ingress protection ratings like Type 4 or 4X are required. Verify compatibility with existing switch standards before finalizing the design.

Part Context

This component belongs to the Hoffman E Series of pushbutton enclosures. These units are engineered for straightforward integration into larger control assemblies. The series offers standardized dimensions to simplify panel layout planning. They are commonly used in manufacturing and processing industries where operator interfaces require robust physical protection.

Replacement Considerations

Direct substitutes include other Hoffman E Series enclosures with identical 30.5 mm hole patterns. Cross-brand replacements must match the 12.5 x 3.25 x 2.75 inch footprint and Type 12 rating. Ensure any alternative maintains the same mounting hole configuration for seamless retrofitting.
