A604CHEMC

Overview

The A604CHEMC is a steel enclosure manufactured by Hoffman Enclosures, Inc., designed as an EMI/RFI shielded junction box. It features a light gray finish and a continuous hinged door secured with a screw clamp mechanism. The unit measures 6.000 inches in length, 3.000 inches in width, and 4.000 inches in height (152.40mm x 76.20mm x 101.60mm). Constructed from steel, it provides electromagnetic interference protection for sensitive electronic components.

Feature Summary

• EMI/RFI shielding capability for signal integrity
• Continuous hinged door design for secure access
• Screw clamp fastening system

Applications

• Industrial control panels requiring EMI protection
• Sensor junction boxes in noisy environments
• Communication equipment housing

Procurement Notes

Verify the specific shielding effectiveness rating required for your application against manufacturer datasheets. Confirm that the continuous hinge and screw clamp configuration meets your maintenance access needs. Ensure the steel material and light gray coating are compatible with your environmental exposure conditions. Cross-reference dimensions to verify fit within existing assembly spaces.

Selection Notes

Select this model when electromagnetic interference shielding is critical for the enclosed electronics. The compact 6x3x4 inch footprint suits tight installation spaces. The steel construction offers durability, while the hinged door allows repeated access without removing hardware. Consider the screw clamp mechanism for quick opening requirements compared to removable covers.

Part Context

This component belongs to the Hoffman Enclosures line of metal junction boxes. It is part of a series offering various sizes and shielding options. The A604CHEMC specifically addresses applications needing small-form-factor EMI protection. It complements larger NEMA-rated enclosures by providing specialized shielding for smaller assemblies.

Replacement Considerations

Check for direct substitutes with identical shielding specifications and mounting hole patterns. Verify if alternative models offer different hinge types or materials while maintaining the same external dimensions.
