Absolute Single-turn
Absolute encoders, contrary to the incremental ones, deliver their position even after cut of the supply voltage and do not require mechanical repositionning. Single turn professional encoders allows the positionning in the revolution (0-360°).
Absolute encoders provide Gray, binary or other specific code upon request.
Three ranges are available: the 58mm POSI+TM the 90mm ROBUSTECHTM, the 200mm MAXXTM.
Absolute Multi-turn
In addition to the position in the revolution, absolute multiturn encoder provides the number turns which have been made, up to 65,536 revolutions (16 bit).
A complete range of multiturn encoder is available with a mechanical or a patented all electronic memorisation of the number of turns. |

Manufacturer of absolute encoders are devices used to measure lengths or angles and are used as distance gauges in equipment tools, in handling and automation technology and on testing units.
Absolute industrial encoders
These output positional information in the form of a numerical value (code). This numerical value is unique across the entire resolution range of the absolute encoder. For this reason no initial reference run is required, as is the case with incremental encoders.
With shaft encoders, a distinction is made between single-turn encoders, which provide a resolution on just a single rotation and then revert to 0, and multi-turn encoders that provide a resolution over several rotations. A further distinction is made between optical and magnetic encoders. |

These transducers are shaft industrial encoders which give absolute measurements on more than one revolution of their shaft.
The encoders have a mechanic gear train which transmits the movement of its master disc to a series of slave discs for shaft revolution counting.
An electronic circuit cancels any mechanic backlash of the gear train, thus yielding a detection's.
They are mechanically strong and properly engineered in their electronics, optical and mechanic parts, being thus able to withstand heavy duty conditions.

method allows to eliminate every mechanic action of gears
to assure a real absolute value of the recording.
Furthermore it permits to choose the code and the
increment directionhaving in basic configuration as gray
code as binary code as up/down discriminate. |

Its outstanding performance figures makes the absolute rotating encoder GEL 235 clearly superior to both conventional professional encoders and optical systems. Using an innovative technique that reinterprets the familiar vernier principle, the GEL 235 is able to achieve unprecedented precision. This absolute rotary encoder operates wholly reliably even under the most rugged conditions, such as widely fluctuating temperatures and moisture conditions or strong vibration.

Manufacturer of absolute encoders provide a distinctly coded numerical value for each shaft position. In positioning tasks in particular, the absolute professional encoders relieve the follow-up electronics of computation tasks so that complicated and expensive input components can be dispensed with.
Moreover, reference runs when the machine is switched on or after power failures are no longer required as the current position value is available immediately. Parallel absolute encoders transmit the position value to the analysing electronics parallel through several cables. In case of serial absolute encoders the output data can be transmitted by means of standardised interfaces and standardised protocols.
Whilst in the past frequently point-to-point connections were set up for serial data transmission, field bus systems are being used increasingly today.

Incremental encoders
Solid shaft professional encoders
Incremental encoders generate a certain number of pulses per revolution. The number of pulses is a measure of the distance moved (angular or linear).
Hollow shaft encoder
Hollow shaft encoders are always used when reduced installation length is required or when precision is important where the drive is subjected to high acceleration.
Absolute encoders
Singleturn
Absolute encoders provide a specific numerical value (code value) for each angular position.
Multiturn
Multiturn encoders not only detect angular positions but also distinguish between several revolutions.
