Angle Encoder

Angle Encoders

HEIDENHAIN angle encoders are  characterized by high accuracy  values in the arc second range  and better. These devices are  used in applications such as  rotary tables, swivel heads of  machine tools, dividing app- aratuses, high-precision angle  measuring tables, precision  devices in angular metrology,  antennas and telescopes.

 

Line counts typically 9000 to 180000 Accuracy from ± 5" to ± 0.4" Measuring steps as fi ne as 0.000 005° or 0.018" (incremental) or 29 bits, i.e. approx. 536 million positions per revolution (absolute)

 

Because of their high static and dynamic accuracy, the RCN, RON and RPN angle encoders with integral bearings and stator couplings are the preferred units for highprecision applications such as rotary tables and tilting axes. For the units with stator coupling, the specifi ed accuracy includes the error caused by the coupling. For angle encoders with separate shaft coupling, the coupling error must be added to find the system accuracy.

ROD Angle Encoders

with integral bearing, for separate shaft coupling

 

ROD angle encoders with solid shaft for separate shaft coupling are particularly attractive Rod Angle Encoderfor applications where high shaft speeds and large mounting tolerances are required. The precision shaft couplings allow axis motion up to ± 1 mm. For angle encoders with separate shaft coupling, the angular measuring error caused by the shaft coupling must be added to determine the system accuracy.

ERA Angle Encoders

without integral bearing

 

ERA Angle EncoderThe HEIDENHAIN ERP angle encoders without integral bearing are intended for integration in machine elements or components. They operate without friction and permit high accuracy. This makes them particularly attractive for high-precision angle measuring tables and precision devices in angular metrology. The ERP 4080 and ERP 8080 angle encoders are designed for applications in the clean room.

 

The attainable system accuracy depends on the eccentricity of the graduation to the drive shaft bearing, as well as the radial runout and wobble of the bearing.

ECN, EQN, ERN Rotary Encoders

with integral bearing and mounted stator coupling

 

Rotary encoders from HEIDENHAIN serve  as measuring sensors for rotary motion,  angular velocity and also, when used in  conjunction with mechanical measuring  standards such as lead screws, for linear  motion. Application areas include electrical  motors, machine tools, printing machines,  woodworking machines, textile machines,  robots and handling devices, as well as  various types of measuring, testing, and  inspection devices.

 

The high quality of the sinusoidal incremental signals permits high interpolation factors for digital speed control. HEIDENHAIN ECN, EQN and ERN rotary encoders with integral bearing and mounted stator coupling are characterized by simple mounting and short overall length. Possible applications range from simple measuring tasks to position and speed control on servo drives. The hollow shaft of these encoders is slid directly onto and fastened to the shaft to be measured. During angular acceleration of the shaft, the stator coupling must absorb only that torque caused by friction in the bearing.

 

Rotary encoders with stator coupling therefore provide excellent dynamic performance and a high natural frequency.

ECN, EQN, ERN Rotary Encoders

with integral bearing and mounted stator coupling

 

Rotary EncoderRotary EncoderThe HEIDENHAIN ECN, EQN and ERN rotary encoders with IP 40 degree of protection are specially designed for integration in motors. Bearings and mounted stator coupling are integrated. Absolute rotary encoders and versions with commutation tracks are available for synchronous motors. The taper shaft or the blind hollow shaft is fastened directly to the shaft to be measured. This ensures an extremely stiff coupling that permits exceptionally high dynamic performance of the drive. The stator coupling is designed to be fastened in a location bore and permits fast, simple mounting while enabling a mechanical fi ne adjustment of the commutation.

ROC, ROQ, ROD and RIC, RIQ Rotary Encoders 

with integral bearing, for separate shaft coupling

 

Rotary EncoderThe optical encoders ROC, ROQ and ROD, as well as the inductive RICand RIQ from HEIDENHAIN have integrated bearings and are sealed. They provide IP 64 to IP 67 protection, depending on the version. They are robust and compact. These encoders are coupled by the rotor to the measured shaft through a separate coupling that compensates axial motion and misalignment between the encoder shaft and measured shaft.

ECI, EQI, ERO Rotary Encoders

without integral bearing

 

The ECI/EQI inductive rotary encoders are mechanically compatible with the photoelectric encoders ExN: the shaft is fastened with a central screw. The stator of the encoder is clamped in a location hole. The photoelectric ERO modular rotary encoders from HEIDENHAIN consist of a graduated disk with hub and a scanning unit. They are particularly well suited for limited installation space or for applications for which there must be no friction.
