GF27.19-P-5127-04O Speed sensor, function
- Transmission 722.9
- Output speed sensor

Component Identification:

The transmission output speed is recorded using a pulse ring (3) and a Hall difference sensor. This increases the measuring accuracy. 2 Hall generators and a bar magnet are integrated into the output speed sensor (VGS) (Y3/8n3). Magnetic field changes occur due to the rotary motion of the pulse ring (3).

As a result an induction difference arises between the two Hall elements of the Hall generators which changes its polarity due to the rotary motion. This polarity change is converted into an rpm signal by the electronic analysis system and evaluated by the fully integrated transmission control (VGS) control unit (Y3/8n4).
