Incremental encoder is the term given to sensors for recording changes in position (linear or rotating) that can measure both the distance and direction of travel.
They are also known as optical encoders.
Unlike measuring systems that work continuously, incremental encoders have a solid measure with a repeating periodic counting track. The measurement is based on a directional reference and a count. |

The encoders contain a contact-less magnetic detector system and a precision toothed wheel. The sensor’s magnetic field is modulated by the passing of the teeth of the measuring wheel.
The resulting sinusoidal and co-sinusoidal voltage is evaluated by the integrated electronic and converted to an incremental output and optionally to an additional analogue current output.
Advantages of the magnetic system:
* Unaffected by condensation on the measuring wheel and is therefore the preferred choice for applications, where ambient temperatures change or where the relative humidity is high. (e.g. outdoors)
* Unaffected by oil or dirt penetration.
* The steel measuring wheel is highly resistant to shock and vibration, unlike glass or plastic graduated discs in other systems.
* Excellent reliability over a very long life because it does not suffer from the ageing effect common to optical systems.

Incremental encoders supply a certain number of pulses for each shaft revolution. The measurement of the cycle duration or the counting of the pulses per unit of time supplies the speed of the moment. If the pulses after a reference point are added, the calculated value represents a parameter for the scanned angle or the distance covered.
Two-channel encoders - with a phase shift of 90 deg. - enable the follow-up electronic equipment to recognise the direction of rotation of the shaft and thus permit bidirectional positioning tasks.
In addition, three-channel incremental encoders provide a so-called zero signal for each revolution.

Magnetic rotary encoders
To meet the increasing demand for reliable, low cost, high-speed rotary encoding, Renishaw has introduced a range of OnAxis™ magnetic industrial encoders.
These high-speed rotary magnetic encoders are designed for use in harsh environments, such as marine, medical, print, converting, industrial automation, metal working, motor control, and instrumentation.
The magnetic encoder range is designed and manufactured by RLS d.o.o. in Slovenia, Renishaw's partner in encoder technology.

Incremental encoders
Solid shaft 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.
