FAQs
Begin by selecting the EEx d gland for the unarmoured branch, strip the #16 AWG conductors, and perform a proper crimp termination to the silver-plated copper pins. Insert the termination into the 12-shell housing, ensure the inner and outer sheath dimensions match the specified ranges, and tighten the gland to achieve IP68/IP66 sealing. This method reduces ingress paths and ensures compliance with Zone 1 requirements for hazardous locations.
The CEX-133-B12-334PN carries IECEx/ATEX Zone 1 certification, is rated IP68/IP66 for ingress protection, and meets NEMA 6P 4X standards. It is designed for 18 A with #16 AWG silver-plated copper contacts in a male pin configuration with crimp termination, suitable for unarmoured cables in hazardous-area equipment.
Yes. The product is designed for Hazardous/Classified Locations with Zone 1 certification, EEx d gland, and rugged IP66/IP68 protection. It supports critical control and power wiring with reliable sealing, making it well-suited for offshore platforms, refineries, and chemical plants where explosive atmospheres and moisture ingress are common concerns.
Expect IECEx/ATEX compliance for Zone 1 hazardous locations, NEMA 6P 4X rating for harsh environments, and IP68/IP66 ingress protection. These standards ensure safe operation under dust, water exposure, and corrosive conditions, aligning with typical industrial automation and process-control requirements.
The crimp termination with silver-plated copper contacts provides durable electrical connections that resist corrosion and loosening under vibration. The rugged EEx d gland and robust sealing reduce leak risks, extend service life in harsh environments, and minimize downtime—delivering lower maintenance costs and a faster return on investment in hazardous-location installations.
