The Noris FA2J Speed Sensor is designed for Speed Sensing. The FA2J detects the rotation of ferromagnetic toothed wheels by a sensing coil, and is converted by a signal amplifier into a rectangular-pulse signal. The frequency of the rectangular signal is proportional to speed.
Apart from speed, the pick-ups are adapted to detect any movement of ferromagnetic objects. The rectangular signal lends itself to evaluation and transformation by a variety of devices.
