Durable Littelfuse 59025-2-U-02-A reed sensor compact cylindrical design ideal for IoT and energy management
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 work with the 57025 actuator. Key advantages include no leakage current in the 'open' state, making it suitable for battery-powered IoT devices, and its compact size allows for easy installation and effective concealment.
