s Features
1. FR sensor consists of semiconductive magnetoresistors
and a permanent magnet.
2. FR sensor detects the position and the speed of a gear
over a wide range of frequency including a complete halt.
3. Non-contact sensing mechanism guarantees a long life.
4. Rugged and reliable, suitable for motor control for Factory
Automation.
5. A variety of applications is possible with multiphase type.
Target Gear
s Magnetoresistive Effect
A change in the resistance of a ferromagnetic or
semiconductive material when it is subjected to magnetic
flux. Used in Murata's sensor is InSb which exhibits very
high magnetoresitive effect in Fig. 1.

s Principle of Operation
As a magnetic material moves over the sensing surface, the
magnetic flux distribution across the magnetoresistors
varies.
This causes MR element resistance change and produces
output signal as indicated in Fig. 2.
Therefore, when it is placed close to the magnetic gear as
shown in Fig. 3, the sensor output a signal synchronized to
gear rotation.
The count of signal's peaks is equal to the number of gear
teeth passing over the sensor.
