Single-turn absolute rotary encoder / optical / hollow-shaft - ø 35 mm, 13 - 23 bit | ECN 1000 series

Heidenhain ECN, EQN, and ERN models are rotary encoders that feature an integral bearing with mounted stator coupling. The said models have short overall strength and are easy to mount. They are ideal for a variety of applications, ranging from speed and position control on servo drives, even the simplest measuring tasks. These encoders also feature a hollow shaft slid directly and connected to the measured shaft.

The Heidenhain ROC, ROD, and ROQ contain their own sealed bearings. These encoders are compact and rugged in design, coupled by a rotor to the shaft onto a distinct coupling that offsets the misalignment and axial motion between the measured and encoder shafts.
