MAGNETIC POSITION SENSOR WITH IDENTITY CODE AND SECURITY DEVICE USING SAME

摘要

The invention concerns a sensor comprising: a means (6) for generating an identity code for the sensor, including at least a magnetic encoder designed to be driven in rotation by rotary drive means and to move past in front of a sensitive detection cell with magnetic field, the magnetic encoder consisting of a series of variable magnetic field generating elements arranged such that the cell delivers a coding signal (SC) formed by a combination of signals corresponding to the magnetic sensor identity code; and means (11) for analyzing the coding signal (SC) using the reference periodic signal (S0), to read the identity code of the magnetic position sensor (1).
