59040 Reed Sensors

Littelfuse 59040 Reed Sensors are small, cylindrical reed sensors 31.0mm (1.22") long that press into a 9.5mm (.375") diameter hole with a choice of normally open, normally closed, or change-over contacts. Littelfuse 59040 is capable of switching up to 200V_DC at 10W contact rating. An extensive range of sensitivity with a 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. 59040 is well-suited for use in a wide range of industrial, appliances, or IoT proximity sensing applications. It functions best with a 57040 actuator.
