Featuring crush ribs on the capsule that requires no attachment accessories for installation, Littelfuse has introduced the 59040 series press-fit reed sensor. This magnetically operated sensor is designed to press-fit securely into a 9.5mm (3/8”) diameter hole and offers another sensor option for the competitive reed sensor market. Its enhanced sensitivity allows for a wider air-gap between the sensor and its matching 57040 actuator.

The sensor is designed for mounting on a fixed surface/frame with the magnet actuator mounted on the moving surface/door. It offers three contact options: normally open, normally closed and change-over contacts. The 59040 series press-fit reed sensor is a UL Recognised Component and offers switching capability up to 200VDC/140VAC at 10W. A range of sensitivity and cable length options are available.

The magnetically operated switch is ideal for battery-powered applications because the contacts do not draw power when not activated. Typical applications for the 59040 series Firecracker reed sensor include position sensing in appliances, door/window position sensing in security systems; limit sensing in hydraulic cylinders; and speed and distance measuring/sensing for treadmills and bicycles.

“The new 59040 series press-fit reed sensor is an ideal addition to our Firecracker reed sensor portfolio,” noted Will Li, Global Product Manager, Sensors, Littelfuse. ”It offers designers a new sensor option in a popular form factor that’s quick and easy to install.”

The magnetically operated press-fit proximity sensor allows for quick and easy installation without the need for screws, brackets or glue, while retaining ribs on the cylindrical capsule compress when inserted into a standard drill size 9.5mm (0.375") diameter mounting hole to provide retaining force, allowing for secure installation. It mounts in and operates through non-ferrous materials such as wood, plastic or aluminium. The hermetically sealed reed contacts last for millions of operating cycles under MCU voltage and current logic-level loads.

The 59040 series Firecracker reed sensor is available in quantities of 100 pieces in a box with a minimum order quantity of 500 pieces. Sample requests can be placed through authorised Littelfuse distributors worldwide.
