The Hoffman Enclosures Q302013PCEMC is a Type 4X EMC junction box constructed from polycarbonate. It features a screw-on solid cover and contoured body design. Dimensions are 11.81 inches in height, 7.87 inches in width, and 4.84 inches in depth. The enclosure provides electromagnetic compatibility protection and meets NEMA 4X and IP66 ratings for environmental sealing.
Verify the specific model suffix to confirm material composition and rating compliance. Ensure the application environment requires polycarbonate rather than metal construction. Confirm that the EMC shielding requirements align with the product specifications provided by the manufacturer.
Select this model when non-metallic construction is required for corrosion resistance or weight reduction while maintaining high ingress protection. The EMC capability distinguishes it from standard junction boxes. Verify dimensional constraints against available mounting space.
This component belongs to the Hoffman QLINE series of enclosures. The series emphasizes contemporary aesthetics with flush covers and contoured bodies. It serves as a specialized variant within the broader junction box category, focusing on signal integrity alongside physical protection.
No direct public substitute part numbers are confirmed in the provided documentation. Standard Type 4X junction boxes may fit dimensionally but will lack the specific EMC shielding properties of this polycarbonate model.
