A sensor unit for sensing the angular position of a rotating element with respect to a fixed element includes a target fastened to the rotating element and a given number of sensing cells. Each sensing cell is connected to a connection device adapted to provide power supply, transmit data delivered by the sensing cells and connect each sensing cell to the ground. The sensor unit provides an output connector for electrically connecting the sensor unit to a reception device, a power supply system and the ground, via a connection cable having at least two connection wires. The connector includes, for each wire of the connection cable, a connection pin having a clamp portion adapted to receive an end of the wire, and a plug portion adapted to make a pressing contact with the connection device.

Sensor unit for sensing an angular position of a rotating element with respect to a fixed element and bearing assembly comprising such a sensor unit

This method determines an angular position of a rotary element in a system where a magnetic ring rotatably fastened to the rotary element in communication with multiple sensors each suitable for issuing a unitary electric signal representative of a magnetic field generated by the magnetic ring. At least two groups of sensors adapted to generate, based on the unitary sensor signals, at least one combined electric signal representative of the angular position of the magnetic ring. This method comprises; a) verifying the consistency the combined electric signal with at least one given rule b) assessing whether or not each group of sensors is correctly working based on the verification of step a); and if, a first group of sensors is not correctly working, disregarding its combined electric signal and relying on the combined electric signal of at least a second group of sensors for determining an angular position value.
