Industrial grade Littelfuse 59025-1-S-02-A reed sensor with normally open and normally closed contacts
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 a wide range of industrial, appliance, and IoT proximity sensing applications, including security and access control, factory automation, and process equipment. It functions best with the 57025 actuator and can operate through non-ferrous materials. Key advantages include no leakage current in the 'open' state, making it suitable for battery-powered IoT devices, and easy installation with effective concealment.
