A90PM78G

Overview

The Hoffman A90PM78G is a polycarbonate enclosure designed for industrial environments. It features a transparent front door allowing visual inspection of internal components without opening the unit. The housing provides protection against dust and water ingress, rated IP65 when closed. The unit includes mounting provisions for panel installation or surface mounting using the integrated flange. It is constructed from durable, impact-resistant polycarbonate material suitable for harsh conditions.

Feature Summary

• Transparent polycarbonate door for component visibility
• IP65 rated protection against dust and water
• Impact-resistant construction for durability

Applications

• Industrial control panels requiring visual monitoring
• Machine tool electrical enclosures
• Process automation instrumentation housings

Procurement Notes

Verify exact dimensional tolerances and mounting hole patterns against specific panel cutout requirements before procurement. Confirm that the IP65 rating applies only when the door is properly latched and seals are intact. Ensure environmental temperature ratings of the polycarbonate material align with the operational range of the installed electronics. Check for any specific UL or CSA certification marks required by local safety regulations.

Selection Notes

Select this model when visual access to internal wiring or indicators is critical while maintaining environmental sealing. Consider the material compatibility with cleaning agents used in the facility. Evaluate whether the standard gasket material meets chemical resistance needs. Compare overall depth requirements against available space constraints in the equipment layout.

Part Context

This part belongs to the Hoffman A90 series of polycarbonate enclosures. These units are commonly used in factory automation and machinery where lightweight yet robust protection is needed. The series offers various sizes and configurations to accommodate different component densities and interface requirements.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. When replacing, verify that alternative enclosures match the external dimensions, mounting hole spacing, and IP rating. Ensure the replacement material offers equivalent UV resistance and impact strength if used outdoors.
