Abstract: The invention relates to a motor vehicle gearbox position detector comprising a sensor (3) designed to cooperate with a moving target (5) connected to a gearbox ratio actuation element so as to provide at least one analog signal representative of the position of the neutral point of the gearbox, characterized in that it additionally comprises a unit for processing the signal (9) comprising an analog-to-digital converter designed to convert the analog signal into a digital output signal (17) so as to provide periodic predefined information corresponding to the position of the neutral point only when, on the one hand, the target (5) is in the neutral point position and, on the other hand, when the sensor (1) is in the normal operating state.

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.
