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.
