The YASKAWA UTOPH‑600WC is a high-performance internal incremental rotary encoder tailored for Yaskawa AC servo motors. It provides 6000 pulses per revolution via TTL (RS‑422) output, enabling precise speed and position feedback. This encoder mounts directly onto the motor shaft using a compact axial/spring-coupled design that ensures alignment under vibration. With a small form factor (~10 mm shaft bore, ~380 g weight), it supports high-speed operation and reliable feedback in tight spaces. Ideal for CNC automation, robotics, and industrial motion control, it delivers robust performance and long-term durability in demanding conditions.
