Product Overview

The Littelfuse 59022 Reed Sensor is a compact, hermetically sealed cylindrical sensor designed for non-contact switching in a variety of industrial, appliance, and IoT proximity sensing applications. It offers a choice of normally open, normally closed, or change-over contacts, capable of switching up to 200 Vdc at 10 W. Its IP67 rating, UL and REACH compliance, and ability to function through non-ferrous materials make it ideal for wet, harsh environments and applications requiring efficient proximity/access and energy management. The sensor is well-suited for security and access control, factory automation, process equipment, and appliance sensing. It functions optimally with the 57022 actuator and is available with various sensitivity and cable length options.
