Heidenhain: Angle Encoders (RON Series)

The term angle encoder is typically used to describe encoders that have an accuracy of better than ± 5“ and a line count above 10000. In contrast, rotary encoders are encoders that typically have an accuracy of more than ± 10“. Angle encoders are found in applications requiring precision angular measurement to accuracies within several arcseconds.

Examples:

Angle encoders with integral bearing, hollow shaft and integrated stator coupling

Because of the design and mounting of the stator coupling, it must only absorb that torque caused by friction in the bearing during angular acceleration of the shaft. RCN, RON and RPN angle encoders therefore provide excellent dynamic performance. With an integrated stator coupling, the stated system accuracy also includes the deviations from the shaft coupling.

Further advantages:

Angle encoders with integral bearing, for separate shaft coupling

ROD angle encoders with solid shaft are particularly suited to applications where higher shaft speeds and larger mounting tolerances are required. The shaft couplings allow axial tolerances of ± 1 mm.

Angle Encoders with Integral Bearing

HEIDENHAIN angle encoders with integral bearing are characterized in particular by very high system accuracy. The integral bearing in the encoders eliminates any effect on measuring accuracy from the bearing of the machine components.

The integrated stator coupling in the RCN/RON/ECN series encoders guarantees lowest possible error from the effect of tolerances in the shaft coupling. All angle encoders with integral bearings feature shaft seals that ensure resistance to contamination (IP64 protection). These encoders enjoy an entire spectrum of possible applications in machine tools, measuring machines, telescopes, printing machines and many other areas.
