Unique Angle Encoder Modules for Precision Rotary Axes

Heidenhain Corporation (Schaumburg, IL), launches a new product family that is a merger of Heidenhain bearing and angle encoder technologies. Resulting in the MRP 2000 series, 5000 series and 8000 series, as well (as customer-specific variants), these unique modules contain bearing sets not conventionally available and are able to be integrated with various encoder types to yield highly stiff modules that are easy to install. The angle encoder modules represent a successful merging of the key requirements for precision rotary axes used in metrology, calibration devices, automation technology, micro machining, and the semiconductor industry.

Key features of the MRP series bearing, include a remarkably high guideway accuracy combined with high rigidity, a low starting torque and a constant continuous torque. At the same time, value was placed on compact dimensions due to the fact that the bearing raceway are machined directly onto the shaft. Bearing loads up to 300 Newtons are possible while still maintaining the system accuracy.

The encoders fulfill the high requirements for any motion feedback application. Their most important features are high resolutions, excellent signal quality and best repeatability, even when operating temperatures vary. Incremental or absolute encoders can be used as required, with resolutions up to 29 bits. The encoders also ensure low position noise and low position drift.

Each encoder module undergoes an extensive accuracy test involving a unique five-dimensional test for wobble as well as axial and radial guideway accuracies. Therefore, two quality inspection certificates are enclosed with each module. The first certificate documents the system accuracy and the second one documents the guideway accuracy.

Heidenhain is the North American subsidiary of Dr. Johannes Heidenhain GmbH (Traunreut, Germany), a leading international manufacturer of precision measurement and control equipment. Their product line includes linear scales, rotary and angular encoders, digital readouts, digital length gages, CNC controls, and machine inspection equipment.
