する回転数センサの電磁ピツクアツプ。 A rotation speed sensor is configured together with a signal disk plate made of a magnetic material that is connected to the rotating shaft of the rotating body to be detected and has protrusions formed on its outer circumference, and is provided close to the protrusion forming portion of the signal disk plate,
In an electromagnetic pickup that converts changes in the magnetic field when the protrusion passes due to the rotation of a signal disk plate into an electrical signal and outputs it as a rotational speed signal, a magnet and a pair of iron cores sandwiching the magnet are arranged in a rod shape, and one A coil is arranged around the outer periphery of the iron core, a pair of lead wires connected to both ends of the coil are made to protrude from one end of the other iron core, and
A circumferential groove is formed in the other iron core, an O-ring is inserted into the circumferential groove, and the outer periphery of these members is surrounded by an insulator in a cylindrical shape with the protruding end of the lead wire exposed. An insulator part close to the outer periphery of the end face of the lead wire is protruded in an annular shape, and is caulked inward to cover the periphery of the end face of the core, and an O-ring is inserted into the circumferential groove formed on the outer peripheral face of the insulator. An electromagnetic pick-up for a rotational speed sensor, characterized in that the outer side of the lead wire is covered with a cylindrical case having an open end face and a closed end.
