This sensor is made from InSb magnetic resistance. That resistance value changes by the magnetic field and the permanent magnet which gives this sensor magnetic bias. When a magnetic substance approaches the detection side, an output signal can be received because the magnetic flux density which affects the magnetic resistance changes and the resistance value of this senser is changed. Because it is 2 circuit built-in type, it is the most suitable for the use such as a position transducer of the servomotor for the magnetic encoder.

Feature

Rotating direction can be detected for 2 circuit building in.
A magnetic resistance element is an InSb mono-crystal. That sensitivity and the ratio of S/N are high.
It can be detected even if detected material doesn't stick to the detection side.
Output doesn't depend on the movement speed of the magnetic body, and it can detect a stationary body.
A detection part is pure resistance, and hardly catches guidance noise.
It is the miniature metal case package which can use even the limited space
