Product information "Differential magnetoresistive Sensor CY-SMR-04, Power Supply: 5V, Output: Dual outputs(Phase dif. 90°), Alternative for: FR05CM12AL(MuRata)"

The differential magnetoresistive sensor CY-SMR-04 consists of two groups of two series coupled magneto resistors (D-type InSb/NiSb semiconductor resistors whose value can be magnetically controlled). The magneto resistors are mounted onto an insulated ferrite substrate. The sensor is encapsulated in a metallic and plastic package and has 2 output signals. The phase shift between the two output signals is 90°. A permanent magnet, which supplies a biasing magnetic field, is fixed on the base of the sensor.

Characteristics

  • The gear rotation direction can be detected by monitoring the phase shift direction of the two output signals A and B 
  • Wide sensing range, detecting frequency range 0 ~ 100kHz 
  • Good Signal-to-Noise ratio, high resolution, high sensitivity 
  • Contactless measurement, easy to use 

Typical applications

  • Detection of gear rotation speed and direction in factory automation equipments 
  • Detection of the direction of linear motion servo 
  • Motor controller for vehicles 
  • Measurement of needle position in industrial knitting machines
