AL9301

Overview

The Hoffman AL9301 is a NEMA 4X rated enclosure constructed from polycarbonate, designed for harsh environments requiring corrosion resistance and impact protection. It features a hinged door with a quarter-turn latch mechanism for secure access. The unit includes pre-drilled knockouts on the sides and bottom to facilitate cable entry and wiring management. Its compact dimensions make it suitable for mounting in confined spaces while providing IP66 protection against dust and water ingress.

Feature Summary

• Polycarbonate construction provides high impact resistance and corrosion immunity
• NEMA 4X rating ensures protection against windblown dust and rain
• Hinged door design allows for easy access without removing hardware

Applications

• Outdoor industrial control panels
• Marine equipment housing
• Chemical processing plant instrumentation

Procurement Notes

Verify that the specific order matches the exact model number AL9301 to ensure correct material composition and sealing specifications. Confirm that the required cable entries align with the provided knockout locations. Check for any accessory requirements such as gaskets or mounting brackets not included in the base unit configuration.

Selection Notes

Select this model when environmental exposure requires non-metallic materials to prevent galvanic corrosion. Ensure the internal component layout fits within the specified internal volume. Consider thermal dissipation needs as plastic enclosures offer less heat transfer than metal alternatives.

Part Context

This part belongs to Hoffman's line of non-metallic enclosures. It is distinct from metal variants by its dielectric properties and weight characteristics. The series is engineered for applications where chemical resistance outweighs the need for electromagnetic shielding.

Replacement Considerations

Direct substitutes must match the NEMA 4X rating and polycarbonate material. Verify dimensional compatibility if replacing an existing unit. Cross-reference with other manufacturers' IP66 rated plastic enclosures only if physical mounting holes align.
