Fanuc Interface Rotary Encoders Improves Accuracy

HEIDENHAIN’s ROC 400 Series rotary encoders now connect directly to Fanuc controls with alpha or alpha-i interface, providing new levels of versatility for servo and spindle applications. Available with hollow or solid shaft options in single-turn and multi-turn configurations.

ECN/EQN 400F rotary encoders with integrated bearings feature stator couplings that compensate radial runout and alignment errors without significantly reducing accuracy. ROC/ROQ 400F rotary encoders for separate shaft coupling feature integral bearings and a solid shaft. The shaft coupling relieves the encoder bearing of additional loads that normally shorten service life.
