These CambridgeIC Arc Position Sensors have a measuring range of 100°. They are available with Sensor Radius from 25mm to 100mm.
This range of sensors is optimised to work with CambridgeIC’s Standard Target. Two mechanical configurations are possible as illustrated below, Target Inside and Target Outside. Either may be used, to deliver the most convenient mechanical integration.
These sensors are preferably operated with Type 4 CTU circuitry. This means that a single CAM204 chip can process two of these arc sensors, one arc and one linear sensor or one arc and one rotary sensor.
Features
- 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
Performance
- Linearity Error <0.4% at 0.5mm…1.5mm Gap, Target Inside
- Noise Free Resolution > 10.5 bits up to 1.5mm Gap
- Up to 1mm Radial Misalignment
Applications
- Intelligent valves
- Surveillance camera tilt axis angle sensing
- Motorised antenna position feedback
- Vent angle sensing
- Gate opening angle sensing
- Exercise equipment angle feedback
- Vehicle suspension level sensing
- Measurement of handle position
- Actuator position feedback
- Optical and magnetic encoder replacement
