Locking plug
The watertight locking plug design provides a secure, tamper-resistant connection that minimizes accidental unplugging in busy industrial spaces and protects sensitive equipment from moisture ingress. This translates to lower downtime and longer mean time between failures (MTBF) in manufacturing lines. The 20A, 125/250V rating supports common industrial loads, with a three-pole, three-wire, non-grounding configuration that streamlines panel wiring while maintaining safety. Back-wiring compatibility with #18-10 AWG conductors reduces installation time and field errors, delivering faster commissioning and easier maintenance. Nylon face/body plus Santoprene elastomeric sealing deliver durable resistance to oils, chemicals, and washdowns, helping assemblies survive aggressive environments. The color-coding (yellow) enhances visibility for quick inspections in busy facilities. cULus listing and IP67/NEMA 6/4X compatibility provide regulatory confidence and compliance for global operations. Overall, the design supports safer, more reliable connectivity with lower lifecycle costs and predictable performance in demanding settings.

FAQs
The 9965PW uses a back wiring method designed for quick field termination. It supports #18-10 AWG conductors, enabling straightforward installation without additional connectors. Ensure conductors are cleanly inserted to the specified torque range and secured within the nickel-plated brass contacts to maintain a reliable, low-resistance connection in wet or washdown environments.
The 9965PW is rated for 20A at 125/250V and configured as three-pole, three-wire non-grounding. It uses nickel-plated brass contacts and provides a locking plug design to prevent accidental disconnection. Torque during mating and securing is 14-16 lbf-in, ensuring a consistent, vibration-resistant connection in industrial settings.
Yes. The 9965PW is designed for harsh environments with IP67 protection and NEMA 6/4X compatibility, including NEMA 6P/6, ensuring watertight performance in washdowns and exposure to moisture. The yellow nylon body and Santoprene seal enhance chemical resistance and visibility, making it a reliable choice for outdoor panels and wet-location applications.
The 9965PW is cULus Listed, which confirms compliance with UL safety standards for North American markets. This certification supports regulatory approvals in industrial facilities, helps meet procurement and safety audits, and provides assurance to integrators that the connector meets stringent moisture, electrical, and environmental requirements for rugged installations.
To maximize ROI, install using the back-wiring method with #18-10 AWG conductors and adhere to the 14-16 lbf-in torque specification for reliable contact seating. Regularly inspect the locking mechanism and seals for wear, replace if integrity is compromised, and benefit from reduced downtime due to secure connections and resistance to moisture ingress in washdown environments.
