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, making it suitable for a wide range of industrial, appliance, and IoT proximity sensing applications. The sensor is hermetically sealed, IP67 rated, UL and REACH compliant, and can operate through non-ferrous materials. It functions best with the 57025 actuator and is available in select sensitivities and cable length options, with customization available.
