Abstract
It is an object to make it possible for magnetic sensors to be readily disposed in such a manner that the position of the magnetic sensors relative to the rotary shaft corresponds to the design position. The magnetic sensor device 3 comprises a magnetic sensor 4 having a magnetic wire rod that generates a large Barkhausen effect, a yoke 21, a casing 22 in which the magnetic sensor 4 and the yoke 21 are accommodated, and sensor securing portions 28 for securing the casing 22 to a substrate. The terminals 15 of the magnetic sensor 4 are compression terminals, and, as the casing 22 is secured to the substrate by the sensor securing portions 28, the terminals 15 are pressed against conductor portions on the substrate and are electrically connected to the conductor portions.
Claims4
A magnetic sensor device, comprising:
- a magnetic sensor having a magnetic wire rod that generates a large Barkhausen effect, a bobbin having the magnetic wire rod disposed therein, a coil formed by winding an electrical wire around the bobbin, and two terminals provided in the bobbin and intended for respectively electrically connecting one end and the other end of the electrical wire to two conductor portions provided on the substrate, and
- sensor securing portions for securing the magnetic sensor to the substrate with fasteners,
- wherein the two terminals are both compression terminals, and, as the magnetic sensor is secured to the substrate by the sensor securing portions and the fasteners, the two terminals are respectively pressed against the two conductor portions and electrically connected to the two conductor portions.
