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. Ideal for battery-powered IoT applications due to no leakage current in the 'open' state, it facilitates efficient proximity/access and energy management systems. Its hermetically sealed, IP67-rated, UL and REACH compliant design allows operation through non-ferrous materials like wood, plastic, or aluminum. Available in various sensitivities and cable lengths, it functions optimally with the 57025 actuator and is well-suited for industrial, appliance, and IoT proximity sensing applications.
