59025 Reed Sensor
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. Its hermetically sealed, IP67-rated design, along with UL and REACH compliance, ensures reliability. Ideal for industrial, appliance, and IoT proximity sensing applications, it functions best with the 57025 actuator and can operate through non-ferrous materials like wood, plastic, or aluminum. Key benefits include no leakage current in the 'open' state, making it suitable for battery-powered IoT devices, and easy installation for efficient proximity, access, and energy management systems.
