New press-fit reed sensor requires no accessories for installation

Littelfuse has introduced the 59040 Series press-fit reed sensor, the first Firecracker reed sensor with crush ribs on the capsule that requires no attachment accessories for installation. The 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 10W/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. “The new 59040 Series press-fit reed sensor is an ideal addition to our Firecracker reed sensor portfolio,” said Will Li, sensors global product manager, Littelfuse. ”It offers designers a new sensor option in a popular form factor that’s quick and easy to install.” Electronica China, March 15-17, 2016, in Shanghai, Booth 3522 (E3 Hall).
