HEIDENHAIN IBV 3000 Cable Signal Converters
The HEIDENHAIN IBV 3000 series converts 1 VPP incremental encoder signals into TTL signals. Its cable design puts the signal-converter electronics inside the D-sub connector. The current IBV 3x71 family includes IBV 3171, IBV 3271 and IBV 3371, with interpolation options up to 400-fold.
Technical Data

- Protection: IP40
- Mass: 71 g for the IBV without cable, with electronics
Selection and installation
Match the complete IBV ID, interpolation factor, encoder signal frequency and both connectors. Homing and limit signals require encoder support and the specified cable-length limit. The product information gives the model-specific edge separation and pin layouts.
