LINARIX capteurs linéaires

Linear sensors (also known as encoders or wire-rope sensors) are used to measure distance (in motion). For this, the sensor cable is hooked to the moving part and the box remains fixed.

They are commonly used in applications where linear motion monitoring is required for system control or for safety reasons.

Posital has developed a range of LINARIX products. Compared to conventional linear potentiometers or cable potentiometers, LINARIX is more durable and more flexible to configure according to customer needs. The sensors are precalibrated nonetheless scalable, endowed with long lifetimes and capable of monitoring position even without a power supply using absolute rotary encoders for detection.

  • Measuring range, from 1 to 15 m
  • Absolute position measurements with an accuracy of up to 2 µm
  • High linearity, even with long cycle times
  • Economic and resistant design
  • Analog output graduated to adapt to the measurement length
