Eaton L1620CW Watertight Locking Connector - IP67
Part Number: L1620CW
Quick Summary
The Eaton L1620CW watertight locking connector delivers reliable, field-ready connections for industrial equipment in harsh environments, including 480V three-pole, four-wire configurations. Moisture, dust, and washdown exposure can cause corrosion, downtime, and expensive maintenance if seals fail. It carries IP67 ingress protection and RoHS compliance, supporting rugged outdoor or factory-floor installations with regulatory confidence and safer long-term operation. Back wiring and a compact, yellow Santoprene body enable quick terminations and clear visibility, reducing installation time and miswiring risk in tight panels. The combination of these features translates to lower lifecycle costs and improved uptime for critical machinery in automation and process facilities.

Special features
Watertight locking connector
The watertight locking design ensures a secure, moisture-protected connection. This reduces corrosion risk and unplanned downtime in washdown and outdoor environments. Ideal for industrial equipment like pumps and conveyors operating in harsh environments. Compatibility and wiring are optimized for field installs with back wiring supporting quick terminations; torque specifications of 14-16 lbf-in promote reliable contact pressure and long-term performance. This enables faster terminations with consistent electrical performance, reducing commissioning time on new lines and minimizing rework. Material and durability are enhanced by a Santoprene thermoplastic elastomeric body in yellow, offering chemical resistance and high visibility to operators in cluttered or hazardous industrial spaces. Steel contacts provide robust electrical performance for industrial duty and a longer service life in demanding environments. Electrical ratings of 20A at 480V and the L16-20 NEMA configuration meet standard industrial needs while maintaining a compact footprint for panel mounting and serviceability. Compliance and lifecycle advantages come from RoHS compliance and a proven watertight seal, reducing regulatory risk and maintenance costs. Industry context emphasizes cord diameter range 0.36-0.84 in to accommodate a variety of cable glands, ensuring versatility across multiple machines and lines.

FAQs
L1620CW uses a back wiring method and accepts #18-10 AWG wires. The unit is rated for 20A at 480V and employs a 6.75 inch housing with a 4.0 inch height to fit standard industrial panels. Tightening torque is specified at 14-16 lbf-in, ensuring a consistent contact pressure and reliable long-term performance in crowded control cabinets.
IP67 rating means the connector withstands immersion up to 1 meter for 30 minutes, protecting against dust ingress and moisture. In wet environments, this reduces the risk of corrosion, short circuits, and unexpected downtime, enabling reliable operation for outdoors, washdown zones, and chemical processing facilities while meeting demanding industry standards.
Yes. The L1620CW is designed for industrial equipment requiring 480V, three-pole, four-wire configurations, compatible with the L16-20 NEMA arrangement. Its locking mechanism and watertight seal help maintain secure connections under vibration and exposure, making it a robust choice for conveyors, pumps, and other heavy-duty machinery in challenging environments.
The L1620CW is RoHS compliant and features IP67 protection for moisture and dust ingress. These certifications support regulatory alignment in many regions and are essential for applications subject to hazardous substance restrictions and washdown or outdoor use, although it is not specified to carry SIL or CE markings in the provided data.
Watertight locking minimizes moisture intrusion and corrosion at the connection interface, reducing maintenance cycles and extending service life of critical electrical joints. The secure locking mechanism also resists vibration-induced loosening, improving uptime in demanding machinery like pumps and conveyors. Overall, these features lower lifecycle costs by decreasing replacements and unscheduled downtime.
