Locking connector
The L1020CWBK delivers IP67 watertight protection in a compact locking connector design, reducing moisture ingress and ensuring reliable operation on exposed equipment. This feature translates to fewer shutdowns and maintenance cycles in washdown areas and outdoor enclosures, enabling more up-time for conveyors and automation lines. Back-wiring with #18-10 AWG wires and a torque range of 14-16 lbf-in provides secure terminations with predictable seating, accelerating panel assembly in control cabinets and modular machines. The nylon face and body, coupled with nickel-plated brass contacts and a Santoprene elastomeric seal, offer robust corrosion resistance and long service life in harsh environments, minimizing replacement costs. Rated for 125/250V and 20A, with L10-20 NEMA configuration, it ensures compatibility with standard plant power systems, reducing adapters and simplifying wiring in industrial automation projects. The RoHS compliance and cULus listing support regulatory adherence for global deployments, while IP67 and NEMA 4X/6 ratings give confidence for outdoor, damp, and washdown settings. Overall dimensions of 6.38 in length, 3.82 in height, and 4.4 in width, plus a weight of 1.025 lb and a cord dia range of 0.43-1.15 in, help with planning, space, and serviceability in compact enclosures.

FAQs
The L1020CWBK uses back-wiring for #18-10 AWG conductors with a recommended torque of 14–16 lbf-in to ensure a secure connection. The nickel-plated brass contacts provide reliable termination, while the Santoprene seal and nylon body protect against moisture. Follow manufacturer guidelines for stripping length and seating to avoid loosening under vibration.
Rated for 20A at 125/250V with a three-pole, non-grounding arrangement, the connector follows the L10-20 NEMA configuration. This combination supports reliable power distribution in industrial equipment and aligns with standard North American single- or three-phase systems.
Yes. The connector is IP67 rated and listed with NEMA 4X/6 protections, making it ideal for outdoor, wet, and washdown environments where moisture, dust, and temporary immersion pose a risk to electrical joints.
The L1020CWBK is RoHS compliant and cULus Listed NOM, providing regulatory alignment for clean-room, consumer, and industrial installations. These certifications help ensure safety, environmental compliance, and smoother approvals in many global markets.
Using a watertight locking connector reduces maintenance and downtime due to moisture ingress and loose terminations. Its rugged materials, reliable back-wiring, and standard voltage/wire-size compatibility streamline panel builds and service, translating to faster deployment, fewer field faults, and improved uptime in industrial automation.
