Gear Sensor/Switch: Description and Operation

GF26.19-P-4007-02A Gear recognition sensor, function

- TRANSMISSION 716.6
- with CODE (424) Sequentronic automated manual transmission (SEQ)

Component Identification

Operation

The gear recognition sensor (B56/1) is a PLCD (permanent-magnetic linear contactless displacement) position sensor. It operates according to the
inductive principle. A magnet is passed before a fixed coil located in the sensor housing (1), splitting the coil into two zones of different length. The
resultant saturations of the magnetic field are analyzed electronically and transmitted to the automated manual transmission control module (N15/6) in
the form of an analog signal.
