Absolute encoders

Single and multi-turn absolute encoders

Absolute encoders always provide the actual position data at the system power on, despite possible shaft rotations; therefore there is no need to reset to the zero point after a power down.
Stout and accurate, Elap single and multi turn absolute encoders are the ideal solution to releave motions on operating machines in all industrial fields.
The wide choice of mechanical solutions allow to fulfil any application requirement. The different available output signals and voltage supply range make it possible to interface Elap absolute rotary encoders to any counting system or PLC controller. The encoders high resolution values allow to employ them for applications needing a high accuracy degree.

Absolute Encoder development and production

Absolute Encoders are electromechanical angular position transducers, being rotary devices that convert the angular position of their rotating axis into electrical pulses. They are called ‘absolute’ because they instantaneously code the position of the rotor in respect of a zero point, thus providing an absolute reference. Such fact is converted into numerical data via a special circuit and can therefore be processed by an external PLC control, counter or positioner. In magnetic encoders, the position is measured through detection — with a fixed sensor — of the magnetic flux generated by a magnetised rotating disk.


Unlike incremental encoders, both in mono- and multi-turn absolute rotary encoders, the signals code the instantaneous position of the rotor, which is then processed to obtain data on the displacement direction and speed. The advantage of this type of encoder is that even in case of power failure, the measurement is not lost, being in fact absolute. The difference between mono- and multi-turn encoders is that in the first type only the angular position is read, whilst in the latter, the number of turns made by the axis is also measured. In magnetic encoders, the position is detected by measuring with a fixed sensor the variation of the magnetic flux generated by a rotating disk. This contactless system eliminates any wear and tear issues, thus increasing the life of the absolute magnetic encoder.


Absolute rotary encoders are suited to a broad range of applications requiring robustness, speed and thermal resistance in detecting movements on industrial machinery. In order to make the implementation in the most diverse systems easy, models are available with Ethercat, Ethernet IP, Profinet, Profibus, CANopen and SSI interfaces. Depending on the specific needs of the sector, it is also possible to obtain very high levels of precision in:

  • Logistics and factory automation
  • Pallet Installations
  • Snow cannons
  • Safety installations
  • The medical industry
  • Fitness equipment
  • Mechanical carousels
  • Solar tracker control
