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 industrial, appliance, and IoT proximity sensing applications, including security and access control, factory automation, and energy management systems. It functions effectively through non-ferrous materials and is designed to operate with the 57025 actuator. Key advantages include no leakage current in the 'open' state, making it suitable for battery-powered IoT devices, and easy installation with effective concealment.
