Magnetic sensor array structure has transmitter unit extended along circumferential direction of shaft so that axial movement of shaft is increased, and region of transmitter unit is located in detection area of sensor unit

摘要

The magnetic sensor array structure (2) has shaft (3) to perform rotational movements within rotation angle range of less than 360[deg] . A sensor unit is arranged on the shaft. The magnetic transmitter unit (1) is arranged on an outer periphery of the shaft and extended along the circumferential direction of the shaft so that axial movement of the shaft resulting from the achievable axial extreme positions is increased at each of the rotational movement of the shaft position, and region of the transmitter unit is located in detection area of the sensor unit.
