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.
|
|
The absolute 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 keeps information about the position of the shaft even if the power is turned off.

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.

Absolute Encoders output the rotational angle using an absolute code. The rotational position can be detected by reading the code. This eliminates the need to return to the origin at startup.

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.

IGP Series
Using this potentiometer a maximum angular rotation of 3800° can be converted into a voltage proportional to the angle of rotation, through the medium of a conductive-plastic potentiometer.
This special "heavy-duty" version is designed to measure angular or linear displacement under the most difficult of enviromentat conditions. Simply yet robustly built, these units are suitable for use in all manner of industrial applications and engineering industry.
The cast housing is watertight. The single stage gearing is exceptionally backlash-free. Heavy-duty bearings allow for high axial loading on the shaft; gearwheels or even chain drives may be used directly drive the shaft.
Sealing is achieved through the use of a stepped bush whilst electrical connections are made via plug and socket mounted on the side of the unit.
Special features
- reduction gearing 3:1, 5:1, 10:1
- good linearity 0.1 % (standard)
- long life typically 100 x 106 movements

Rotary Shaft Encoders are ideal for use on any rotating shaft to provide a digital output signal to tachometers, counters, speed switches, motor controls, or anything requiring a pulse input. Flexible shaft couplings are available as an option to compensate for shaft misalignment, and are recommended for most applications.
Electro-Sensors Rotary Shaft Encoders convert shaft rotation into square wave output pulses. They provide an accurate means of transmitting actual speed information for detecting rate, position, or direction of rotation. The shaft encoder produces an output signal by rotating a disc with clear and opaque segments between a light emitting diode and a photo-transistor sensor. The output signal from the encoder is then converted into a square wave signal by an internal squaring circuit. The number of output pulses per shaft revolution is determined by the number of clear and opaque segments on the disc. Quadrature (bi-directional) models have a second LED and sensor positioned 90-degrees apart to produce two square wave signals.
Features:
- Ideal for Use on Slow Speed Applications
- Provides Precise Pulse Train for use with Tachometers, Counters, Speed Switches and Speed to Analog Converters
- Multiple Mounting Configuration for easy Installation
- Wide Variety of Pulse per Revolution Counts are Available
- Please Specify PULSES PER REVOLUTION (PPR) When Ordering
