Document Type and Number:
Japanese Patent JP7192624
Kind Code:
B2
Abstract:
The utility model provides a rotating speed sensor. In a rotational speed sensor provided with a sensor head in which a plurality of sensor ICs are embedded, the reliability of the rotational speed sensor is improved. The rotational speed sensor has a sensor head, two sensor ICs embedded in the sensor head, and a cable (3) having an end located in the sensor head. In the cable (3), a twisted wirecomposed of insulated wires (61a, 61b) connected to one of the two sensor ICs and insulated wires (62a, 62b) connected to the other one of the two sensor ICs passes through the twisted wire. On the cross section of the cable (3), the insulated wires (61a, 61b, 62a, 62b) are arranged at positions corresponding to four corners of the quadrangle, the insulated wires (61a, 61b) are arranged at positions opposite to each other of the corners of the quadrangle, and the insulated wires (62a, 62b) are arranged at positions opposite to each other of the corners of the quadrangle.
