Durable Littelfuse 59025-2-T-02-A reed sensor hermetically sealed compact design suitable for proximity sensing
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 its no leakage current in the 'open' state, it facilitates efficient proximity/access and energy management systems. Its hermetically sealed, IP67-rated design, coupled with UL and REACH compliance, ensures durability and reliability. The sensor can operate through non-ferrous materials and is available with various sensitivity and cable length options, making it suitable for industrial, appliance, and IoT proximity sensing applications. It functions optimally with the 57025 actuator.
