This is Omron quadrature incremental rotary encoder E6B2-CWZ1X with 1000 P/R (pulse per revolution). The encoder outputs is line drive (RS-422 compatible) and long-distance transmission is possible up to 100m

This allows you to add feedback to motor control systems. Encoders of this kind are often used in CNC machines, balancing robots and dead reckoning navigation.

This encoder is of improved reliability with reverse connection and load short-circuit protection
