Omron WLCA32-43LD-N Limit Switch
Omron WLCA32-43LD-N is a two-circuit limit switch with a Fork Lock Lever C actuator and LED operation indicator for industrial position detection. The lever configuration supports mechanical actuation in machine mechanisms, while screw terminals with a G½ conduit entry simplify field wiring. The built-in LED gives technicians quick visual confirmation of switch status during commissioning and maintenance, and the switch supports low-level control signals. IP67 protection suits demanding factory installations. The WLCA32-43LD-N belongs to the WL Series within the heavy-duty two-circuit limit switch range from Omron automation products for machine position and motion detection.

The Omron WLCA32-43LD-N Limit Switch uses a Fork Lock Lever C actuator for mechanical position detection in industrial control systems and includes an LED operation indicator for visible switch-status confirmation. Screw terminals with a G½ conduit entry support field wiring, while the switch can handle microloads down to 5 VDC at 1 mA resistive load. Rated operating voltage extends from 10 to 115 VAC/DC. The indicator has reference leakage current of approximately 0.4 mA at 10 VAC/DC and 0.5 mA at 115 VAC/DC. IP67 protection supports installation around dust, water, and demanding factory machinery.
Electrical integrity is supported by 100 MΩ minimum insulation resistance at 500 VDC and an initial built-in-switch contact resistance of 25 mΩ maximum. The WLCA32-43LD-N operates from -10 to 80°C with 35 to 95% relative humidity. It withstands destructive shock of at least 1,000 m/s² and malfunction shock of at least 300 m/s², while malfunction vibration resistance covers 10 to 55 Hz at 1.5 mm double amplitude. The lever actuator, LED indication, microload capability, and screw-terminal wiring make the model useful where operators or maintenance teams need both mechanical detection and visible operating feedback. For another LED-equipped WL model using direct plunger actuation, see the WLD18-LD-N.
