FIELD: automotive industry.
SUBSTANCE: device has a sensor made of a magnetically flexible material and secured to the shaft. The sensor has cylinder provided with spiral slots. One half the cylinder is provided with slots inclined at +45 degrees, and the other half the cylinder has slots inclined at -45 degrees. The material between slots is a part of the right-hand and left-hand thread spiral, respectively. Two inductive coils embrace both halves the sensor.
EFFECT: simplified design and enhanced reliability of pickup.
