Incremental rotary encoder ERN 1000

blind-shaft5VDC4.5VDC

Incremental rotary encoders with integral bearing High axial tolerance of up to ±0.5 mm Blind hollow shaft Positioning accuracy of down to ±18" 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.
