The Yokogawa DM1B-075G DD is a High-Resolution, Incremental Hollow Shaft Encoder from Yokogawa's "Flexcoder" series.
This model is designed as a robust and cost-effective solution for measuring speed and relative position in industrial applications. Its key feature is the hollow shaft (or "through-bore") design, which allows for easy installation over motor shafts or other equipment, simplifying alignment and reducing mounting hardware.
