A90PM78BG

Overview

The Hoffman A90PM78BG is a polycarbonate enclosure designed for industrial environments. It features a transparent cover allowing visual inspection of internal components without opening the unit. The housing provides protection against dust and water ingress, rated IP65 when properly sealed. Dimensions are approximately 9 inches in height, 9 inches in width, and 7.8 inches in depth. The unit includes mounting provisions for standard DIN rail or panel installation.

Feature Summary

• Transparent polycarbonate construction enables direct visual monitoring of internal equipment status
• Sealed design ensures environmental protection against dust and low-pressure water jets
• Integrated mounting hardware supports flexible installation configurations

Applications

• Enclosure for electrical control panels requiring visual access
• Protection for instrumentation and sensors in industrial settings
• Housing for pneumatic or hydraulic valve manifolds

Procurement Notes

Verify exact dimensional tolerances and sealing gasket specifications against the official Hoffman datasheet before integration. Confirm that the IP65 rating applies only when the cover is securely fastened with the provided hardware. Ensure mounting surfaces are compatible with the included attachment points to maintain environmental integrity.

Selection Notes

Select this model when visual inspection of enclosed components is required without compromising environmental protection. Consider the polycarbonate material properties regarding UV resistance and impact strength relative to the operating environment. Verify that the internal volume accommodates all necessary components with adequate clearance for heat dissipation if active cooling is not used.

Part Context

This part belongs to the Hoffman Polycarbonate Enclosure series, which offers lightweight and corrosion-resistant alternatives to metal housings. The series is designed for applications where weight reduction and transparency are prioritized over extreme mechanical impact resistance found in steel or aluminum variants.

Replacement Considerations

Check for updated part numbers from Hoffman Enclosures as product lines may be discontinued or superseded. Verify compatibility with existing mounting brackets and sealant requirements when substituting with similar transparent enclosures from other manufacturers.
