What is a Rotary Position Sensor?

A Rotary Position Sensor measures position in a rotary fashion; either clockwise or anticlockwise. They can be described as an electromagnetic device which emits an electrical signal which corresponds to the angle of rotation of an object around a shaft.

Rotary Position Sensors can use various types of technology, these can be either contacting or non-contacting. At Positek, our rotary position sensors use our own PIPS technology which is non-contacting.

What is a Rotary Position Sensor Used for?

Rotary Position Sensors can be used for a variety of applications throughout many different industries, some of these applications include;


  • Steering wheel position
  • Steering systems in heavy-duty machinery
  • Gear position in vehicles
  • Pedal positioning
  • Industrial process and control systems
  • Various OEM applications
  • Camera angles in security cameras
  • Marine applications including rudder references in boats and ships
  • Various medical applications


Some applications specific to Positek Rotary Position Sensors are;


Water Jets for Support Vessels - Our rotary position sensor is used to sense the position of the reverse duct and steering cylinders.

Valve Positioning - the rotary position sensor feeds information into the plc programme comparing the incoming signal with the signal of the valve.

Textile Carding Machines - Our rotary position sensor controls the tension on the delicate bundle of cotton fibres as it is passed through various processes.


Different Types of Rotary Position Sensor

There are different types of rotary position sensor. Using different technologies;

Positek PIPs - our rotary position sensors use patented inductive sensor technology. They are highly robust and suitable for the industry's harshest environments.

Hall Effect Rotary Sensors - another non-contacting design; Hall effect sensors use magnetic fields to help determine position. Our sister company Variohm Eurosensor holds a range of Hall effect sensors. See them here.

RVDTs - Rotary Variable Differential Transformer use metal coils and a metal core. Our Positek Sensors work on a similar principle to RVDTs.
