It is capable of switching up to 200 Vdc at 10 W Contact rating. Extensive range of sensitivity with specified cable length is available. The housing color is white. It has three crush ribs along the length of the capsule that allow a firm and fixed press-fit. It is well suited for use in a wide range of industrial, appliances, or IoT proximity sensing applications. It functions best with the 57040 actuator.
