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. This hermetically sealed, IP67 rated sensor is ideal for battery-powered IoT applications due to its zero leakage current in the 'open' state. It facilitates efficient proximity/access and energy management systems, with easy installation and effective concealment. The sensor can operate through non-ferrous materials and is available with various sensitivity and cable length options, functioning optimally with the 57025 actuator. It is well-suited for industrial, appliance, and IoT proximity sensing applications, including security and access control, factory automation, process equipment, and major and small appliances.
