Product Overview
The Littelfuse 59150 is a flange mount reed sensor designed for reliable proximity sensing in industrial, appliance, and IoT applications. Measuring 28.57mm x 19.05mm x 6.35mm, it offers a choice of normally open, normally open high voltage, normally closed, or changeover contacts, capable of switching up to 265Vac/300Vdc at 10VA. Its robust, hermetically sealed, IP67-rated housing allows for M3 screw or adhesive mounting and is suitable for harsh environments. The sensor functions best with the matching 57150-000 actuator and can operate through non-ferrous materials, making it ideal for security, factory automation, and energy management systems. Customization options for cable length and termination are available.
