Omron WLCA12-TH-N Heat-Resistant Roller Lever Limit Switch
Omron WLCA12-TH-N is a heat-resistant roller lever limit switch designed for mechanical position sensing in industrial equipment exposed to elevated operating temperatures. It uses an adjustable roller lever actuator and a two-circuit, double-break switching configuration with a rated load of 10 A at 500 VAC. Screw terminals provide the electrical connection, while the G1/2 conduit opening is specified without a ground terminal. The adjustable roller lever allows the actuator position to be set according to the required machine contact point. For heat-resistant WL applications, the WLCA12-TH-N belongs to the adjustable roller lever limit switch range available across Omron Industrial Control Products.

The Omron WLCA12-TH-N Roller Lever Limit Switch is specified with a heat-resistant function for applications where the surrounding operating environment requires a higher-temperature limit switch configuration. Its actuator is an adjustable roller lever, allowing the lever position to be set to match the mechanical contact path of the moving component. The electrical configuration is two-circuit, double-break, with a rated load of 10 A at 500 VAC. Screw terminals provide the wiring connection, while the switch includes a G1/2 conduit opening without a ground terminal. The adjustable roller arrangement supports mechanical switching where the machine part approaches from the side or along a controlled travel path rather than pressing a fixed plunger directly.
Specified durability includes a minimum of 10,000,000 electrical operations and 500,000 mechanical operations according to the supplied data. Selection should consider the heat-resistant requirement, adjustable roller lever actuator, rated load, two-circuit double-break switching arrangement, screw-terminal connection, and G1/2 conduit opening. The absence of a ground terminal should also be checked against the intended wiring arrangement before installation. For a related WL Series roller-lever option with a different configuration, refer to the Omron WLCA12-LE-N. Its individual specifications should be reviewed separately before selecting the appropriate model for the machine application.
