Short Stroke Linear

Short Stroke Linear sensors are built using conventional PCB technology and detect the position of a standard target without mechanical or electrical contact.  They are robust, simple and tolerant of misalignment and large gaps.  

Measuring Length is typically up to 6mm, although the target is detected over a much greater (but non-linear) range.

The short stroke sensor is a Type 4 sensor (find out more about how sensors are classified and what this means for CTU selection in our FAQ). The CAM204 Central Tracking Unit (CTU) chip can measure up to four Type 4 sensors and the CAM312 can measure up to 2 sensors. Specific development boards are available for testing (see below).

Features

  • Simple non-contact target
  • Full absolute sensing
  • Standard 4-layer PCB process
  • Only 3 wires required for connection
  • Stable across temperature
  • Highly repeatable

Applications

  • Thickness measurement
  • Structural monitoring
  • Vibration analysis
  • Actuator position feedback
  • LVDT replacement

 

Performance

  • Up to 5mm Target Gap
  • < ±0.25% Linearity Error over 5mm Measuring Length at 1mm Gap
  • Up to ±1mm Y Misalignment

Testing and development

The following are recommended for getting started with the Short Stroke sensor:

  • Short Stroke sensor(s)
  • Standard Targets for each sensor
  • 300mm 6-way Sensor Connecting Cable for each sensor
  • A CAM312 or CAM204 Development Board for processing
  • A CTU Adapter for communicating with a PC over a USB interface
  • CambridgeIC CTU Software (create account, log in and download)
