Generally, a device called “transmission” is mounted on the vehicles such as motorcycles and cars, which run on the engine power. There are two basic types of transmission systems: manual and automatic. Automatic transmission can change gears without any input from the driver. The transmission is the device which keeps rotating speed of the engine within proper range by the combination of the gears.
Typically, the magnet is attached to the end of the gearbox’s input shaft and the sensor is placed outside the gearbox’s housing.
Our sensor detects the position of the gear, such as first or second, and sends the data as electric signal to the Engine Control Unit (ECU). It generates an output voltage proportional to the angle of the input shaft.
There is an air gap between the magnet and the sensor, so there is no wear that otherwise would result in mechanic abrasion and electrical discharge sparks.
