HEIDENHAIN ND200 Series

Single Axis Displays for Length and Angle

Heidenhain ND200 Digital Readout 

The ND200 series offers digital readouts for one linear encoder or length gauge.

Although primarily designed for measurement applications, the ND287 can also be used for simple positioning tasks such as infeed for a circular saw, the stroke of press travel, or the position of an additional rotary table on a machine tool. The switching inputs and outputs of the ND 287 permit operation also in simple automated environments.

For measuring and inspection stations where measuring results are sent to a printer or to a PC for further processing, there are display units with USB, RS-232-C/V.24 serial output or Ethernet 100BaseT (option only with ND287).
