The Heidenhain 336963-17 belongs to the ERN absolute encoder family, engineered specifically for high-precision angular position measurement on rotary shafts in CNC machine tools, industrial robots, and servo drive systems. This singleturn model provides an absolute position value within one revolution (360°), eliminating the need for reference runs or homing procedures after power cycles, which significantly reduces startup times and improves productivity in automated manufacturing environments. Its innovative design integrates precision ball bearings and a highly accurate stator coupling directly into the encoder housing, ensuring backlash-free mechanical transmission, exceptional vibration resistance (up to 1000 m/s² shock/250 m/s² vibration per typical Heidenhain specs), and simplified mounting without additional couplings or adapters.
Featuring Heidenhain’s proprietary optical scanning technology with grating disk and photoelectronic sensors, the 336963-17 delivers nanometer-level resolution and signal accuracy better than ±5 arcseconds, supporting interfaces like EnDat 2.2, DRIVE-CLiQ, or SSI for seamless integration with modern PLCs and motion controllers. The robust aluminum or stainless steel housing (IP64/IP65 rated) protects against coolant, chips, and contaminants common in machining centers, while hollow shaft or solid shaft options accommodate various motor shaft diameters. Operating reliably from -40°C to +100°C, it withstands over 10^9 signal periods and offers MTBF exceeding 50,000 hours, making it ideal for 24/7 high-duty-cycle applications requiring maintenance-free reliability and diagnostic capabilities via integrated electronics.
