Schaumburg, Illinois – Heidenhain is expanding its small-diameter 1000 and 1100 series rotary encoders with added versions available with Siemens DRIVE-CLiQ. Models ECN/EQN 1000S, ROC/ROQ 1000S, and ECN/EQN 1100S rotary encoders with integrated DRIVE-CLiQ interface feature a compact design with 35mm diameter, while permitting an operating temperature of 95°C.

The combination is certified by Siemens and is an addition to Heidenahin’s existing small-diameter 1000/1100 series encoders that have the same mounting dimensions using EnDat and SSI interfaces.

ECN/EQN 1100S encoders for integration into motors feature a single turn resolution of 23 bits and, as with the standard rotary encoders, a mechanical multiturn gear with a resolution of 12 bits. The ECN/EQN 1100S series rotary encoders also feature a 6mm hollow shaft with an anti-rotation element and a stator coupling. They are mechanically connected by axial clamping with mechanical fault exclusion and are suitable for Functional Safety applications in accordance with SIL 2, Category 3, PL d.

The ECN/EQN 1000S series rotary encoders are available with a 6mm blind hollow shaftfor radial clamping and a stator coupling, while the ROC/ROQ 1000S series encoders are available with a 4mm solid shaft and a synchro flange.
