Abstract

A motor vehicle gearbox position sensor includes a magnet and a probe for measuring a magnetic field at a sensitive end. The magnet and the probe may be placed facing a moving target connected to an actuating element, which is used to select the gear ratios of a gearbox in order to determine the position of the target in space and, from this, deduce the position. The position sensor also includes at least one ferromagnetic element positioned at the periphery of the sensitive end to trap metallic contaminants. A motor vehicle gearbox includes an actuating element that selects gear ratios, a moving target connected to the actuating element, and a position sensor.
