FAQs
For Zone 1 installations, ensure the EEx d gland is properly seated on unarmoured cable within the specified inner (10.0–15.5) and outer (13.5–21.0) sheath ranges, and perform a precise crimp termination with #12 AWG conductors. Confirm IP68/IP66 sealing and correct mating with the corresponding Roughneck connector to maintain hazardous-location compliance.
The CEX-133A16-312PN is certified for IECEx/ATEX Zone 1 operations, rated NEMA 6P 4X, and provides IP68 and IP66 protection. These certifications ensure safe operation, dust and water ingress resistance, and reliability in demanding environments such as chemical plants, petrochemical facilities, and mining operations.
Yes. It is designed for #12 AWG conductors with crimp termination and utilizes an EEx d gland for cable entries. The unarmoured cable configuration and 6.57 in length shell (Size 16) support compact panel mounting and straightforward field termination, compatible with the Roughneck multi-pin family and standard gland entries.
Typical applications include hazardous-area motor control, pump and valve assemblies, and sensor/actuator wiring in chemical processing, oil & gas exploration, and mining. The Zone 1 rating and rugged construction enable reliable operation under vibration, dust, and moisture, while maintaining compliance with IECEx/ATEX and NEC/CEC standards.
Users can reference the Roughneck literature and installation sheets, including IF 1683 instruction sheets, the Roughneck brochure, hazardous-area catalog pages, and the Eaton specification sheet for CEX-133A16-312PN.
