Product Overview
The Littelfuse 59025 Reed Sensor is a compact, cylindrical, non-contact switching solution designed for wet and harsh environments. Available in normally open, normally closed, or change-over contact types, it offers a choice of sensitivities and cable length options. 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, process equipment, and major/small appliances. It functions best with the 57025 actuator and can operate through non-ferrous materials. Its 'open' state has no leakage current, making it suitable for battery-powered IoT applications. The sensor is UL Recognized per UL 508 and CSA C22.2 No. 14, and REACH compliant.
