PRODUCT ADVANTAGES

  1. Compact in design yet powerful in torque output.
  2. Exceptional precision with absolute positioning accuracy maintained at less than 20 arc seconds.
  3. Resilient to environmental conditions, featuring IP65 and IP54 protection standards.
  4. Designed for zero maintenance, eliminating the need for lubricant replacement throughout its lifespan.
  5. Enduring durability, with consistent accuracy maintained even after extensive use exceeding 15,000 hours.

PRODUCT DESCRIPTION

The SIS Series encompasses both high-voltage and standard models, characterized by an exceptionally large hollow shaft, equipped with dual encoders, and featuring a braking system.

This system features an integrated dual absolute encoder with dual-loop control, providing a 16-bit absolute encoder for the output shaft. It guarantees repeatability at ±7 arc seconds and absolute accuracy up to ±15 arc seconds, while retaining the real absolute position and multi-turn count even during power-off.
