LITTELFUSE Plastic Barrel Reed Sensor, M8 Thread, Normally Closed

The LITTELFUSE Plastic Barrel Reed Sensor is a robust, magnetically operated proximity switch designed for reliable position and limit sensing. With its M8 x 1.25 threaded barrel and supplied retaining nuts, it offers simple installation and precise adjustment in a variety of mounting scenarios.

This sensor features a normally closed (NC) contact configuration and operates without any standby power requirement, making it an energy-efficient choice for continuous monitoring applications. Its key capability is to switch loads up to 265V AC or 300V DC at 10VA, and it excels at interfacing directly with microcontroller logic-level loads, simplifying integration into digital control systems.

A significant advantage is its ability to operate effectively through non-ferrous materials such as wood, plastic, or aluminium, allowing for concealed or protected installation. The sensor comes with a 300mm cable fitted with tinned leads for reliable electrical connections and corrosion resistance. For optimal performance, it is designed to function best when paired with the compatible 57070 actuator, which is sold separately.

Built to withstand demanding environments, it operates reliably across a wide temperature range from -40°C to 105°C. Its compact, threaded plastic barrel design is both durable and versatile, suited for automated systems where space and reliability are critical.
