By converting shaft rotation into electronic pulses, encoders are used to electronically monitor the position of a rotating shaft. The encoder’s output pulses are counted and evaluated by a control unit to determine machine position and velocity, which provides exceptional accuracy and flexibility when controlling motion. The high mechanical and electronic operating speeds associated with optical encoders increase system speeds and accuracy, decrease cycle times, and boost overall productivity in the manufacturing environment. Autonics rotary encoders of various sizes and types offer high-quality and precise measuring of the operating position and speed of the rotating shaft, etc. for more precise control of the objects.

The photoelectric rotary encoder is used to establish an informational link between the key components of machines, industrial robots, comparators and DCC, NC or Digital Readout units. It gives information about the value and direction of the motion components. The encoder is used in automatic control, on-line gauging, in process monitoring systems, etc.
The encoder consists of three parts: mechanical, optical and electronic.
The case of the encoder is fixed to an object by means of screws. The shaft of the encoder is connected with an object shaft by virtue of a compensating coupling.

Hohner Automazione encoders are high precision position/speed transducers. They are used to sample these quantities
on a revolving axle. The encoder converts the input analog signal to digital signal, so that it can be handled by a computer device. The conversion is carried out by a coded wheel, integral with the transducer shaft, read by a photoelectronical system.

Absolute encoders are devices used to measure lengths or angles and are used as distance gauges in machine tools, in handling and automation technology and on testing units.
Absolute 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 rotary 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.

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 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.

Absolute coders MT
The multi-turn absolute coders seize the mechanical movement of rotation of a drive on several revolutions. Absolute coders ST
The absolute coder ST
delivers for each angular position a value of coded position single. The value of absolute position is available as of the interlocking of the system. For this reason, a race of reference during the interlocking of the system is superfluous.

Absolute encoders have a unique value (voltage, binary count, etc) for each mechanical position. When an absolute encoder is turned on, the position of an absolute encoder is known.

Resolvers are absolute encoders offering a high level of availability, even under extreme conditions. These encoders were developed for the positioning of anti-aircraft guns a good 60 years ago, and are today used in all imaginable applications. MICRONOR resolvers are suitable for use in all extreme conditions where a standard encoder is no longer sufficient, e.g. for speeds of up to 100,000 rpm or in the presence of high levels of radio-activity, at temperatures of -60°C or 280°C, or when exposed to high impact stresses.
Our FE resolver units are available for any absolute multi-turn requirement. We can pair the resolvers in a single unit, in accordance with either the master-slave principle or the Vernier principle.

Distances, positions and angles - when a precise positioning is required in the area of industrial engineering, an encoder is just unbeatable.
When making distance measurements the resolution of the encoder is in the micrometer range, when making angular measurements it is equivalent to very few thousandth degrees.
In this way machines and components of all kinds can be positioned very precisely.
Absolute, non-contact length measuring systems, wire-draw encoders and compact measuring wheel encoders complete the offer.
