Principle Vehicle Speed Reed Sensor

The reed sensor is installed in the combined instrument. The reed switch is a switch element composed of two elongated contacts installed in a glass tube. The contacts are made of magnetic materials. When acted by a magnetic field, the two contacts will attract each other and close or repel each other and open.

The vehicle speed reed sensor consists of a rotor with four magnetic poles and a reed switch. When the output shaft of the transmission drives the rotor to rotate through the flexible shaft, the reed switch will periodically switch under the action of the permanent magnet of the rotor. Every time the rotor rotates, the reed sensor is opened and closed four times, and 4 outputs are output through the external circuit. pulse. If the pulse signal is sent to a digital circuit or computer for counting and calculation, the vehicle speed output can be obtained.
