Product Overview
The Littelfuse 59025 Reed Sensor is a compact, cylindrical, non-contact switching solution designed for wet and harsh environments. It offers a choice of normally open, normally closed, or change-over contacts, capable of switching up to 265 Vac/300 Vdc at 10 VA. Its hermetically sealed, IP67-rated design, coupled with UL and REACH compliance, makes it ideal for industrial, appliance, and IoT proximity sensing applications, including security and access control, factory automation, and energy management systems. It functions best with the 57025 actuator and can operate through non-ferrous materials, allowing for effective concealment and easy installation.
