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. Ideal for battery-powered IoT applications due to no leakage current in the 'open' state, it facilitates efficient proximity/access and energy management systems. Its small size allows for easy installation and effective concealment in a wide range of industrial, appliance, and IoT proximity sensing applications. It functions best with the 57025 actuator and is hermetically sealed, IP67 rated, UL and REACH compliant. The sensor can operate through non-ferrous materials like wood, plastic, or aluminum and is available with various sensitivity and cable length options.
