Basic Linear Sensors

Basic linear sensors are robust and simple.  Standard designs are available from 25mm to 300mm measuring length.

The basic linear sensor is a Type 1 sensor (find out more about how sensors are classified and what this means for CTU selection in our FAQ). A single CAM204 Central Tracking Unit (CTU) chip can operate up to 4 Type 1 sensors, including a mix of linear and rotary.

For new designs, customers should also consider a Type B Linear Sensor used together with its matching Type B Linear Target and the CAM622 processor.  This is because the target is simpler, being built from a PCB, and occupies less space. The CAM622 procesor also offers dramatically higher speed and resolution than the CAM204 and CAM312.

 

 

Features

  • Simple non-contact target
  • Full absolute sensing
  • Standard 4-layer PCB process
  • Stable across temperature
  • Highly repeatable

 

Applications

  • Motion control
  • Actuator position feedback
  • Precision front panel controls
  • Valve position sensing
  • Industrial potentiometer replacement
  • LVDT replacement

Performance

  • Up to 5mm Target Gap
  • < ±0.25% Linearity Error at optimum Target Gap
  • Position change < ±0.2mm across -40°C…85°C, ≤ 3.5mm Target Gap
  • < ±0.25mm Position Offset Error
  • Up to ±1mm Y Misalignment
  • Can be installed 2mm from aluminium sheet
