The Omron WLCA2-LE-N is a robust two-circuit limit switch built for precise actuation in industrial environments. It features a roller lever actuator with a 38 mm radius, supporting consistent detection of mechanical motion. The unit offers screw terminals with a G½ conduit and a pretravel angle of 15±5°, enabling easy installation and accurate response in confined spaces.
Designed to handle low-level signals, it supports a minimum load of 5 VDC, 1 mA (resistive, P level), and operates at voltages from 125 to 250 VAC. A built-in neon lamp provides clear visual feedback on operation status. With high insulation resistance (100 MΩ at 500 VDC) and low contact resistance (25 mΩ max), it ensures stable signal transmission over time.
Tested for durability, the WLCA2-LE-N withstands vibration (10–55 Hz) and shock (up to 1,000 m/s²). Its sealed housing resists dust, oil, and moisture, offering reliable performance with IP67 protection.
