Press-fit Reed sensor eases installation

March 16, 2016 // By Julien Happich
The 59040 Series press-fit Firecracker reed sensor from Littelfuse comes with crush ribs on the capsule that requires no attachment accessories for installation.

This magnetically operated sensor is designed to press-fit securely into a 9.5mm 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 Recognized Component and offers switching capability up to 200VDC/140VAC at 10 W/VA. A range of sensitivity and cable length options are available.

Typical applications 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.
