ERN 1000 series

Incremental rotary encoders with integral bearing

  • High axial tolerance of up to ±0.5 mm
  • Blind hollow shaft
  • Positioning accuracy of down to ±18"
  • Max. operating temperature: 100 °C
  • Interfaces: 1 VPP, TTL, and HTLs
  • Housing diameter ≈ 35 mm

Direct shaft coupling

The encoder's hollow shaft allows it be directly coupled to the mating shaft. No additional rotor coupling is required. The high rigidity permits higher control-loop bandwidths while significantly reducing inaccuracy and installation complexity.

Precise positioning

Rotary encoders with a bearing and stator coupling ensure consistently high accuracy. Thanks to optimally matched components, system accuracies of down to ±18 arc seconds are attained.

Flexible coupling

The stator coupling compensates for play between the motor and the rotary encoder, thereby correcting inaccuracy. Even tilt and axial play of up to ±0.5 mm can be reliably compensated for. The stator coupling also facilitates easy mounting to the plane surface.

Compact design

The rotary encoders of this series feature high ruggedness and reliability in a compact design with an outer diameter of just 35 mm. Their small footprint makes them ideal for very tight installation spaces.
