FAQs
Install the plug using the Eex d gland specified for Zone 1 environments, and terminate with crimp contacts for reliable current path and vibration resistance. Ensure the inner sheath is within 10.5–15.5 mm and outer sheath within 13.5–21.0 mm to maintain proper seal, and verify the 12-shell, 3-contact configuration matches the mating connector. Follow the IF 1683 installation guidance for hazardous-area assemblies to ensure compliant gasketing and ingress protection.
The CEX-133-A12-327PN is rated for 30A with #12 AWG conductors and a pin contact configuration. It features an Eex d gland for Zone 1 hazardous locations, unarmoured cable compatibility, and an IP68/IP66 rating along with a NEMA 6P 4X enclosure, suitable for immersion and harsh washdown environments.
Best suited for hazardous-area control panels, pumps, and motors in oil & gas, chemical processing, and mining where Zone 1 environments exist. Its robust sealing and gland protection support reliable operation under exposure to water, dust, and explosive atmospheres, while the 30A rating and #12 AWG compatibility align with common control-system wiring practices.
This connector carries IECEx/ATEX certifications for Zone 1 hazardous locations, NEC/CEC standards, and IP66/IP68 ingress protection, plus a NEMA 6P 4X enclosure rating. It is designed for Hazardous/Classified Locations, ensuring safe operation under explosive atmosphere conditions and demanding industrial environments.
The CEX-133-A12-327PN reduces maintenance downtime through reliable gas-tight sealing and robust gland protection, minimizing re-terminations and field errors. Its standardized Roughneck design accelerates commissioning, while corrosion-resistant contacts and durable housing extend service life in harsh environments, delivering lower total cost of ownership over the asset lifecycle.
