In rotary encoders with integral bearing and stator coupling, the graduated disk of the encoder is connected directly to the shaft to be measured. The scanning unit is guided on the shaft via ball bearings, supported by the stator coupling. During angular acceleration of the shaft, the stator coupling must absorb only that torque resulting from friction in the bearing, thereby minimizing both static and dynamic measuring error. Moreover, the coupling mounted on the stator compensates axial motion of the measured shaft. Other benefits of the stator coupling are:
Simple mounting
Short overall length
High natural frequency of coupling
Hollow-through shaft possible
Rotary encoders with integral bearing that are conceived for separate shaft coupling are designed with a solid shaft. The recommended coupling to the measured shaft compensates radial and axial tolerances. Angle encoders for separate shaft couplings permit higher shaft speeds.
Rotary encoders without integral bearing operate without friction. The two components - the scanning head and the scale disk, drum, or tape - are adjusted to each other during assembly. The benefits are:
Large diameter of hollow shaft
For high shaft speeds
No additional starting torque

Absolute rotary encoders provide a distinctly coded numerical value for each shaft position. In positioning tasks in particular, the absolute encoders relieve the controller of computation tasks and keep costs down by eliminating the need for additional input components.
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 analyzing electronics through several parallel cables. Serial absolute encoders transmit their output data via standardized interfaces and protocols.
In the past, point-to-point connections were frequently set up for serial data transmission but today fieldbus systems are being used more often.
Interfaces:
The Pepperl+Fuchs rotary encoder portfolio includes the most varied range of current interfaces for absolute encoders to be found on the market:
Parallel Interface
SSI-Interface
AS-Interface
CAN
DeviceNet
Ethernet
PROFIBUS

Incremental rotary encoders supply a certain number of pulses for each shaft revolution. Speed is measured by counting the pulses for a period of time. To calculate angle or the distance covered, pulses are counted starting from a reference point.
Dual channel quadrature output encoders feature two signal outputs that are 900 out of phase with each other. This permits the controller to determine direction of rotation and perform bi-directional positioning tasks.
In addition, three-channel incremental encoders have a third signal channel (known as “zero”, or reference, signal) that provides a single pulse for each revolution.

These transducers are shaft 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.

The wide diversity of knowledge and experience, built up over many years within the Wachendorff group of companies, has logically konsequent been used to integrate a new product series into the production program. This has resulted in an innovative range of absolute encoders for CANopen, “Made by Wachendorff in Germany”, that are based on the magnetic principle. They come in single or multiturn versions, with a clamping or synchro flange, or as blind hollow shaft encoders.
The WDGA series was first shown at the SPS/IPC/DRIVES 2008 exhibition in Nuremberg and met with a lot of interest.
The Wachendorff absolute encoders are designed in accordance with the communication profile CiA DS-301 and to the device profile for encoders CiA DS-406 V3.2 class C2. An LED is provided for status signalization as per DR303-3. The WDGA absolute encoders can be configured, without a bus cover, via LSS (layer setting services) to DS-308, or optionally via SDO (service data objects). They offer comprehensive CANopen functionality: position, speed and acceleration objects, limit switch and cam switch functions, up to four individually configurable Transmit-PDO (process data objects), Heartbeat and Nodeguarding as well as other comprehensive diagnostic possibilities, which take into account important aspects of safety.
As ever, the WDGA absolute encoders boast an industrially rugged construction, offer a high level of precision measurement and withstand high bearing loads.

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.
