Omron WLCA32-43-N Limit Switch
Omron WLCA32-43-N is a two-circuit limit switch with a Fork Lock Lever C actuator for mechanical position detection in industrial machinery. The lever configuration supports controlled angular actuation, while screw terminals with a G½ conduit entry provide secure field wiring. This version is supplied without an operation indicator, making it suitable where visual status feedback is handled elsewhere in the control system. IP67 protection supports demanding factory conditions. The WLCA32-43-N belongs to the WL Series within the fork lever industrial limit switch range from Omron machine automation products for dependable machine position and travel detection.

The Omron WLCA32-43-N Limit Switch uses a Fork Lock Lever C actuator for mechanical position detection in industrial control systems. The lever arrangement supports angular actuation from moving machine mechanisms, while screw terminals with a G½ conduit entry provide secure field wiring. This version is supplied without an operation indicator, making it suitable where switch status is handled elsewhere in the control system. Maximum pretravel is 55°, and the switch operates at 50/60 Hz. IP67 protection helps the unit withstand dust and water, while the operating temperature range of -10 to 80°C supports demanding factory conditions.
Electrical integrity is supported by insulation resistance of 100 MΩ minimum at 500 VDC and initial contact resistance of 25 mΩ maximum for the built-in switch. The WLCA32-43-N withstands destructive shock of at least 1,000 m/s² and malfunction shock of at least 300 m/s². Malfunction vibration resistance covers 10 to 55 Hz at 1.5 mm double amplitude, and relative humidity can range from 35 to 95%. These characteristics suit robust lever-operated position sensing where screw-terminal wiring, sealed construction, and no local indicator are preferred. For a closely related version using the same Fork Lock Lever C actuator with an LED operation indicator, see the WLCA32-43LD-N model.
