The speed sensor is mainly composed of a housing and a coil. The housing protects the internal parts of the product, and the coil outputs a signal.
Working principle: The electromagnetic speed sensor mainly transmits the rotation angle position information of the engine crankshaft or the rotating parts linked to the crankshaft to the electronic controller, so that the electronic controller can obtain the crankshaft speed according to the frequency of the rotation angle position signal.
Product features: no need for power supply, simple circuit, stable performance, low output impedance, high output voltage sensitivity.
