• Description

  As an angle sensor that is both accurate and economical, this rotary potentiometer is suitable for all types of analog angle measurement up to 350°.

  Typical fields of application include:

  • Position feedback in servo-systems
  • Pendulum weighing machines
  • Cam and butterfly flap positions
  • Jockey roller controllers
  • Measuring the tension of threads and tape
  • Trigonometric measurements at joints

  The heart of the potentiometric angular displacement sensors is an extremely precise, low-wear resistor track made of plastic. Due to its high resistance to abrasion, the sensors are particularly suitable for measurements for the purpose of quality assurance in ongoing production, where a long service life and large numbers of rotations are required.

  The potentiometric angular displacement sensor uses a multi-finger slider system with precious metal contacts. This ensures good contact even when moving at high speed and in the presence of vibrations.

  The high-precision resistor tracks are pressed in a lasercontrolled process and are therefore remarkably flat. This provides ideal conditions for a long service life.

  The stainless steel shaft is supported by close-tolerance, low-friction, stainless steel ball bearings with double sealing discs.
