Angle Encoders

HEIDENHAIN Angle Encoders

Angular accuracy down to a few arc seconds

HEIDENHAIN angle encoders measure angular position with very high accuracy on rotary tables, swivel heads, and other precision axes. Choose sealed versions with an integral bearing for robustness, or modular versions for maximum flexibility in your design.

How to choose

Angle encoder with integral bearing
Integral bearing or modularIntegral-bearing encoders (RCN, RON, RPN, ROD, ROC, ECN) come sealed and ready to mount. Modular encoders (ERA, ECA, ERP, ERO, ERM, ECM) combine a separate scale and scanning head.Integral bearingModular
Absolute angle encoder
Absolute or incrementalAbsolute encoders (RCN, ROC, ECN, ECA, ECM) know their position at power-up. Incremental encoders (RON, RPN, ROD, ERA, ERP, ERO, ERM) count from a reference mark.AbsoluteIncremental
Magnetic modular angle encoder
Optical or magneticModular encoders are available with optical scanning (ERA, ECA, ERP, ERO) or magnetic scanning (ERM, ECM).OpticalMagnetic
Scale drum angle encoder
Scale and mountingModular versions use circular scales or scale drums in many size and scanning-head combinations.Modular
Angle encoder interface
Interface and accuracyTell us the interface your control expects and the accuracy you need, or send the ID number from your current encoder.
