The ND 221 B is offered for simple tasks at measuring and testing stations, but also for position display on X-Y tables.

The ND 281 B serves as a universal display unit for linear and angular measurement because the display mode can be easily s
witched through a simple code number.

The ND 231 B with sum/difference display allows you to connect two encoders.
