CAM Sensor Arc Type 4

100° Arc Sensor Type 4: R25/30/36/48/68/100mm

These arc sensors measure angle over a range of up to 100°. They measure the position of a target running along an arc, which allows sensor and target to be positioned away from the rotation axis (“off-axis”). This provides space for shafts, bearings and other machinery which needs to be positioned nearer the rotation axis.
Sensor designs are available with different Sensor Radius, so that customers may select the one which best fits their application.
The sensor is connected to a CambridgeIC CTU chip such as the CAM204, which combines the information from both sets of coils to deliver an absolute, high accuracy and high resolution output to a host system.


  • Full absolute sensing along 100° of arc
  • 4-layer PCB process
  • Target is sensed from FRONT or REAR of sensor
  • Target may be positioned to the inside or outside
  • Optimised for Type 4 CTU chip circuitry
  • Functions with Type 1 circuitry, lower performance
