FAQs
This plug accepts inner sheath 7.0–12.0 mm and outer sheath 10.5–16.0 mm, with #16 AWG silver-plated copper conductors and crimp termination. Use the EEx d gland to seal the gland entry and crimp the socket contacts to the conductors. Ensure the seal and gland orientation meet Zone 1 requirements and verify IP66/IP68 integrity after assembly.
The CEX-133A212-333SN complies with IECEx/ATEX Zone 1 hazardous location ratings, NEC/CEC standards, and NEMA 6P 4X. It also provides IP66/IP68 ingress protection, making it suitable for harsh environments and providing global regulatory alignment for hazardous-area installations.
Ideal for oil and gas, chemical processing, mining, and water/wastewater facilities where Zone 1 protection and robust enclosure sealing are required. It supports unarmoured cables with crimped solder-free contacts, delivering reliable performance for motors, pumps, and control panels in hazardous locations.
Crimp termination provides a consistent, gas-tight connection with minimal air gaps, reducing resistance fluctuations and vibration-related faults. It speeds up installation, lowers training requirements, and simplifies future cable replacements, contributing to lower maintenance costs and improved total cost of ownership.
With IP66/IP68 protection, Zone 1 hazardous location certification, and a rugged EEx d gland, the plug is built for long service life in demanding environments. Its unarmoured construction and silver-plated copper contacts resist corrosion and wear, supporting predictable performance across chemical plants, offshore facilities, and mining operations.
