Feature → Business Impact → Application: 30A amperage rating ensures sufficient current capacity for typical motor and control circuits in hazardous zones, reducing the risk of overloads and nuisance tripping. This translates to higher machine uptime and lower maintenance costs in chemical, oil & gas, and mining environments where Zone 1 classification is common. Feature → Application: Eex d gland with cable gland compatibility provides a certified, dust-tight and water-tight seal, simplifying installation and ensuring ongoing ingress protection (IP68/IP66). Operators benefit from reliable sealing during washdowns and harsh weather, ideal for offshore platforms and on-site assembly. Feature → Application: Unarmoured cable type and #12 AWG silver-plated copper contacts support durable, corrosion-resistant connections with crimp termination, enabling quicker field retrofit and lower contact resistance over life. Feature → Application: Socket, female contact configuration in shell size 12 supports compact multi-pin or single-pole arrangements, delivering flexible deployment in space-constrained electrical panels and hazardous-area junction boxes. Feature → Application: 6.57 in length and 1.75 in width/height provide a compact yet rugged footprint, allowing easier clearance in cramped cabinets and reduced enclosure size. Feature → Application: IP68/IP66 and NEMA 4X/6P ratings combine to meet stringent protective standards, improving operator safety and reducing the need for additional enclosure cooling or protection. Feature → Application: NEC/CEC and IECEx/ATEX certification ensure global compliance, simplifying procurement for multinational projects and easing regulatory audits. Feature → Application: Crimp termination and socket contacts minimize field termination errors and speed up installation while maintaining high-reliability connections for critical process lines.

FAQs
The CEX-133-A12-310SN uses an Eex d gland and a robust wiring interface designed for zone 1 environments, providing a certified seal that simplifies installation and reduces the risk of ingress. Its compact shell size 12 and crimp-ready #12 AWG contacts accelerate field termination while maintaining compliance with IECEx/ATEX and NEC/CEC standards.
Yes, the connector is specified for #12 AWG conductors and uses crimp termination with socket (female) contacts. This combination delivers low contact resistance, reliable current transfer up to 30A, and faster field assembly in hazardous-area applications.
The CEX-133-A12-310SN carries IECEx/ATEX for Zone 1 hazardous locations and NEC/CEC compliance, along with IP68/IP66 sealing and NEMA 4X/6P ratings. These certifications ensure safe operation in explosive atmospheres, enable cross-border project deployment, and simplify regulatory audits for global manufacturers.
With IP68 and IP66 ratings, the connector offers strong protection against dust and water ingress, enabling reliable operation during washdowns and in wet or dusty plants. This reduces enclosure complexity and maintenance downtime while extending service life in harsh environments.
The combination of 30A capability, durable silver-plated copper contacts, and certified hazardous-location performance translates to fewer faults, lower replacement costs, and faster installation. For multi-site operations, this can reduce downtime, streamline compliance tasks, and deliver measurable savings on maintenance and project lead times.
