SICK SRS50-HZA0-S21 Motor Feedback System (1037395)

SRS50HZA0S21 – The SICK SRS50-HZA0-S21 is a high-precision motor feedback encoder with a custom hollow shaft design and robust mechanical structure tailored for dynamic servo motor control applications. With 1,024 sine/cosine periods per revolution, ±52 arcsecond system accuracy, and a maximum speed of 12,000 min⁻¹, it enables exact position tracking in high-performance rotary systems.

Its compact housing, radial 8-pin male connector, and resilient rubber stator coupling offer optimal integration flexibility. This model supports position value programming and is supplied with a pre-screwed Torx M5 × 45 fixing screw.

Note: Mounting screws for stator coupling or servo clamps not included in delivery.
