摘要： A sensor arrangement for an absolute measuring position detection system based on a magnetic code object has a substantially linear arrangement of magnetic field sensors, wherein a bit pattern encoded on a single-track magnetic code object having a uniform bit length is readable by the magnetic field sensors. In the case of a position detection system having the sensor arrangement, the values of magnetic bits are detected in the range of a detected bit sequence and the position of each 0→1 and 1→0 bit transition along a longitudinal axis of a code object is determined from the detected bit values.
