Simple position display unit for up to 3-axes

ND 5023 Digital readout 

The ND 5023 digital readout is suited for use on manual milling, drilling and boring machines as well as lathes with up to three axes. Due to the TTL encoder input, primarily the LS 328C and LS 628C linear encoders with a measuring step of 5 μm are used.


With its sturdy housing and splash-proof membrane keyboard, the ND 5023 is built for the workshop. With its clearly organized and user-friendly user interface, operation of the ND 5023 is very simple. The 7-inch TFT color monitor displays all the information you need to machine your workpieces


The ND 5023 offers many useful functions for machining with manually operated machine tools. You can access the most important functions quickly and directly via function keys. Soft keys with language sensitive information in plain languageprovide context-sensitive operation.

The distance-to-go display facilitates positioning tasks. It enables you to approach the next position quickly and reliably by simply moving until the display reads zero.

Of course the ND 5023 also offers special functions for milling and turning operations, such as:

  • Hole patterns
  • Radius/diameter switching
  • Sum display for the top slide

You can individually configure the display of the ND 5023 and save your settings in the user management.

Data Interfaces

A USB interface enables the display unit to output measured values and import or export parameters and tables.
