The YASKAWA UTSIH‑B17CA is a high-resolution internal incremental encoder engineered for seamless integration with Yaskawa AC servo and spindle motors. Part of the UT series, it delivers 17-bit resolution (≈ 131 072 positions) and utilizes TTL/RS‑422 quadrature output for precise speed and position feedback. Designed to mount directly on the motor shaft with a spring-coupled axial plate, it ensures durable alignment under vibration. Built for industrial reliability, it supports a wide operating temperature range and long-term stability in harsh conditions. Ideal for motion control, CNC systems, robotics, and automation requiring compact, integrated encoder feedback.
