Heidenhain 334752-97 Rotary Encoder ERN/ROC Incremental 1024 Lines

Heidenhain 334752-97 appears to be a specific ordering code for a Heidenhain rotary encoder, most likely from the ERN 1331 série (incremental) ou ROC/ERQ absolute famille, based on similar part patterns and catalog references. These encoders mount on motor shafts via stator coupling ou clamping ring, delivering 1024 lines per revolution (incremental) with options for FinDat 2.2 digital interface ou 1 VPP analog sine/cosine signals for high-speed position and speed feedback. Resolution can reach 13 bits (8192 positions/rev) with interpolation, précision ±5–10 arcsec, and speeds up to 6000 tr/min.

The encoder features integral bearing, sealed housing (IP64/IP65), and operates from DC 3.6–14 V with low power consumption (~0.6 W). It’s designed for servo drive feedback in CNC, robotique, et automatisation, compensating for thermal expansion and vibration. Mechanical specs include shaft loads axial 150 N/radial 350 N et moment of friction <20 mNm. Compatible with Fanuc/Mitsubishi drives via EnDat protocols.
