Dynapar G0522586 RI58-O/360EG.43KB Encoder

The Dynapar G0522586 (Hengstler RI58-O/360EG.43KB) is a compact 58 mm incremental rotary encoder designed for direct mounting at motor shafts in high-precision industrial applications. This hollow-shaft model delivers 360 pulses per revolution with push-pull output signals, operating reliably across a 10–30 V DC supply range and temperature span of –10 °C to +70 °C. Built with Opto-ASIC sensing technology, the encoder offers robust immunity to electrical and electromagnetic interference, making it suitable for demanding environments including CNC machine tools, motor drives, and automation equipment. The encoder features a 12 mm hollow bore with concentric clip coupling for simplified and safe shaft attachment, IP65 protection for contaminated environments, and integrated control circuitry with alarm output capability. Maximum pulse frequency reaches 200 kHz in push-pull mode, supporting real-time feedback applications. The compact 41.5 mm housing depth enables tight integration into space-constrained layouts while maintaining high signal accuracy and repeatability across shock loads up to 1000 m/s² (6 ms).
