The Heidenhain 533110-01, model RCN 226, is a premium singleturn absolute angle encoder engineered for direct mounting on rotating shafts in CNC machine tools, motor spindles, and precision robotics. Its hollow through-shaft design (20mm diameter) allows passage of cables, cooling lines, or shafts without disassembly, while the integrated precision bearing and stator coupling ensure backlash-free transmission, high stiffness, and exceptional resistance to axial/radial forces, vibration (250 m/s²), and shock (1000 m/s²). This configuration eliminates the need for separate couplings, reducing installation complexity and improving dynamic response in high-speed applications up to 15,000 rpm.
Utilizing Heidenhain’s advanced optical scanning with pure grating period scanning, it achieves ±5 arcsecond system accuracy and delivers 23-bit resolution (8,388,608 positions per revolution) via the 1 Vpp analog interface, enabling sub-arcsecond interpolation in modern servo drives. The robust IP64-sealed aluminum housing withstands coolant, chips, and contaminants, with a 1-meter radial cable assembly terminated in an M23 17-pin male coupling for reliable signal transmission. Operating on low-voltage DC (3.6-5.25V), it provides diagnostic LEDs, MTBF >80,000 hours, and natural aging compensation for consistent performance over >10^9 signal states, making it indispensable for closed-loop position control in 5-axis machining centers and automated production lines.
