Sealed Absolute Angle Encoders with Integrated Stator Coupling

With accuracies of up to 2 arc seconds, absolute angle encoders provide the absolute position value immediately after switch-on or after a disturbance without prior axis movement.

The encoder photoelectrically scans pure binary patterns on a glass graduated disk to determine the absolute position value.

An RCN absolute angle encoder features an integral stator coupling which, in comparison with encoders with solid shaft and separate coupling, provides the following advantages:
Higher system accuracy
During angular acceleration of the shaft the coupling takes up only the torque resulting from bearing friction
Shorter overall length
Simpler mounting

An IP 64 degree of protection enables RCN angle encoders to withstand the harsh environments typically found around machine tools.

In addition, the RCN 220 and RCN 723 are mechanically compatible with the RON 200 and RON 7x6/RON 8x6 series incremental rotary encoders.
