Rpm and phonic wheel sensor
Specifications:
Gap
0.8 - 1.5 mm
Winding resistance
860 ohm ± 10% at 20°C
- Rpm sensor
- Phonic wheel
The rpm sensor is fitted on the crankcase and faces a phonic wheel located inside the crankcase and fastened to the crankshaft.
The steel phonic wheel is fitted with two reference dowels on the outer part of the circumferenc, each one located 10° after top dead centre.
When these dowels or teeth pass beneath the sensor, the gap brings about a change in the magnetic flux which in turn induces a current in the sensor coil windings.
This signal provides the control unit with information on engine rpm.
