Dynapar G0550326 RI58-O/4000EK.42KH Incremental Rotary Encoder, 4000 PPR, 10,000 RPM, IP67, RS422 Output

The Dynapar RI58-O/4000EK.42KH is an incremental rotary encoder offering 4,000 pulses per revolution, providing precision feedback for motion control and positioning applications across industrial manufacturing equipment. This encoder combines optical sensing technology with a compact 58 mm flange-mount design, delivering high signal accuracy and repeatability in demanding environments including machine tools, CNC systems, packaging machinery, and injection molding equipment. The unit operates continuously to 10,000 RPM and is rated for IP67 protection, vibration resistance to 100 m/s² (DIN EN 60068-2-6), and mechanical shock up to 1,000 m/s² (DIN EN 60068-2-27), making it suitable for high-shock industrial applications. Standard output configurations include RS422 or push-pull (open-collector) signal formats with complementary A, B, and N channels. Key Specifications: - Resolution: 4,000 PPR (pulses per revolution) - Maximum Speed: 10,000 RPM - Output Format: RS422 or push-pull variants with 200–300 kHz maximum pulse frequency - Shaft Options: 6 mm (synchro flange, 20 N axial / 40 N radial load) or 10 mm clamping flange (40 N axial / 60 N radial load) - Operating Temperature: ?10 °C to +70 °C (RI58-O standard version) - Electrical: 5, 10, or 24 V DC supply; typical current draw 30–60 mA depending on supply voltage - Enclosure: Aluminum housing, approximately 360 g; M4×5 mounting threads - Connector: PVC cable with axial or radial exit; optional M23 12-pole connector available - Cable Bending Radius: ?40 mm (fixed installation), ?100 mm (flexible installation) Mounting flexibility includes synchro flange, clamping flange, and optional square flange configurations. The encoder is compatible with standard servo-ring mounts for phasing adjustment and integrates with industry-standard motion control platforms via quadrature output.
