Eaton L1120CW Watertight Locking Connector - IP67
Part Number: L1120CW
Quick Summary
The Eaton L1120CW watertight locking connector is a rugged industrial power solution designed for reliable outdoor and harsh-environment applications. When field wiring is exposed to moisture, dust, or vibration, traditional connectors can fail, leading to downtime and maintenance costs. This model leverages an IP67 watertight seal and RoHS compliance to protect critical connections, while its L11-20 NEMA configuration and three-pole design ensure safe, standardized power delivery. Built for industrial environments, the L1120CW supports back wiring with #18-10 AWG, delivering robust performance with visibility (yellow) and quick-locking reliability, making it a strong fit for motors, conveyors, and other heavy equipment. For procurement teams, this translates to lower lifecycle costs and faster installation with existing equipment.

FAQs
Yes. The L1120CW uses the L11-20 NEMA configuration and supports back wiring for #18-10 AWG conductors, enabling secure terminations with a straightforward installation flow. Its three-pole, 3-wire design matches common industrial power circuits, simplifying replacement and upgrades in equipment such as conveyors and motors.
The connector is rated for 250 V and 20 A, with IP67 protection for watertight reliability. RoHS compliant, it supports durable operation in dusty or wet environments. The three-pole configuration and steel contacts ensure robust current handling and mechanical integrity in industrial applications.
Ideal for outdoor installations, wet processing plants, and environments with heavy moisture exposure or vibration. Its yellow, high-visibility housing aids quick identification, while the watertight design minimizes ingress during exposure to rain, washdowns, or splashing fluids.
The L1120CW is RoHS compliant and features IP67 protection, aligning with industrial environmental and safety expectations. It uses a NEMA L11-20 configuration for standardized power connections and is suited for equipment requiring rugged, field-terminating connectors in harsh settings.
The watertight seal and rugged Santoprene elastomeric components reduce ingress and wear, lowering maintenance frequency and downtime. Back-wiring with secure terminations speeds field servicing, while robust materials (steel contacts, durable housing) translate into longer service life and lower replacement costs over the device’s operational life.
