Current catalog specifications

May 2026 HEIDENHAIN Rotary Encoders catalog, 349529-2S. This supplement applies only to the current model and ID combinations listed below.

ROC 1023 and ROQ 1035 use EnDat 22 with 23-bit positions per revolution. ROC 1013 and ROQ 1025 use EnDat 01 with 13-bit positions per revolution and 512-line 1 VPP incremental signals. ROQ models measure 4096 revolutions. System accuracy is ±60 arc seconds. Solid shaft diameter is 4 mm; mechanical speed is up to 12000 rpm, protection IP 64, and mass approximately 0.09 kg. Supply is DC 3.6 to 14 V. Maximum operating temperature is 100 °C; minimum is -30 °C with fixed cable and -10 °C with moving cable, subject to catalog speed and supply conditions.

Valid current IDs: ROC 1023 1438892-xx; ROC 1013 1438891-xx; ROQ 1035 1438894-xx; ROQ 1025 1438893-xx. Check the ID on the encoder before applying this sheet. Older 2009 configuration sheets remain below for historical units.
