Product Description
This model features a roller lever actuator and a SPDT (Single Pole Double Throw) contact configuration, providing reliable switching for control circuits. With a robust die-cast aluminum housing and IP67 protection, it withstands harsh conditions including dust, water, and oil, making it suitable for machine tools, conveyors, and process equipment. This limit switch is rated for 10A at 250VAC (resistive load) and 6A at 250VAC (inductive load), with a mechanical life of 15 million operations and an electrical life of 750,000 operations. The snap-action mechanism ensures consistent performance and high repeatability. The WLCA12-2N-N is equipped with a 2N roller lever that can be adjusted in multiple positions, offering flexibility in actuator orientation. Omron's WL series is known for its durability and global certifications, including UL, CSA, CE, and CCC. The switch operates within a temperature range of -10°C to 80°C and is designed for easy wiring with screw terminals. Its compact size and standardized mounting dimensions (30mm x 55mm x 30mm) make it a direct replacement for many existing limit switches in the market. The Omron WLCA12-2N-N is a heavy-duty limit switch from the WL series, designed for precise position detection in industrial automation environments.

Technical Specifications
Version & Model Difference
The WLCA12-2N-N is part of the WL series, which includes various actuator types and contact configurations. Compared to the WLCA12-2N (without the -N suffix), the -N version indicates a specific contact material (gold alloy) for low-level switching applications. The WLCA12-2N-N is also available in different contact forms (e.g., DPDT) and actuator options (e.g., plunger, roller plunger). The -N suffix typically denotes a version with improved contact reliability for low-current circuits.
