Angular positioning system comprises encoder, bearing, torque motor in one package

The new SRP 5000 angular positioning system from Heidenhain incorporates the MRP 5000 angle encoder, bearing technology, and an ETEL torque motor with ultralow detent torque. The system provides very high stiffness and can be used as an alternative to rotary air bearing systems for metrology.

The compact system can be ordered in incremental or absolute models. The incremental versions have encoders with 30,000 signal periods per revolution and system accuracies to +/-2.5 arcseconds. The absolute version has the same accuracy level and resolution to 28 bits via the EnDat 2.2 interface.
