Dynapar G0522672 RI58-O/5000AS.41RB Encoder

The Dynapar G0522672 (Hengstler RI58-O/5000AS.41RB) is a compact, rugged incremental rotary encoder designed for precision motion control in industrial automation and machine tool applications. This optical encoder delivers 5000 pulses per revolution with RS422 differential output, providing high signal accuracy and immunity to electromagnetic interference. The unit features a hollow 6 mm shaft with flange mounting, operates across ?10°C to +70°C, and delivers RS422-compatible signals at frequencies up to 300 kHz, making it suitable for real-time feedback in CNC machinery, servo drives, and packaging systems. With IP65 ingress protection and rated shock resistance of 1000 m/s² (6 ms), this encoder withstands high mechanical stress typical of metalworking and injection molding equipment. Supply and electrical characteristics: 4.5–5.5 V DC input, typical current draw 40 mA at 5 V DC. The encoder outputs three channels (A, B, N) plus complementary signals and an optional alarm output. Standard cable termination includes M12 8-pin or M23 12-pin connectors; custom connector and cable configurations are available. The RS422 push-pull output is compatible with standard industrial control interfaces and motion control cards. Mounting and mechanical design: 58 mm aluminum body with multiple flange options (including 63.5 mm × 63.5 mm and 80 mm × 80 mm variants). Hollow shaft design supports direct coupling to motor shafts or auxiliary drive systems. Pulse width accuracy is ±25° electrical, with stable operation across typical manufacturing vibration environments. Typical applications include: machine tools and CNC axes, packaging and labeling machines, motor/drive feedback systems, injection molding machines, sawing and cutting equipment, and textile machinery.
