One Axis DRO.  For Basic Uses

What is the difference between DRO100 and DRO203 and the DRO300?
The ACU-RITE® DRO100 is the entry level basic digital readout system.  

  • In the 100 series, DRO101 works with one axis, DRO102 two axes and DRO300 three axes.

  • The DRO203 model works with two or three axes from A to Z and Z0.

  • The DRO100 series provides the most popular readout functions.

  • The DRO203 provides those, plus convenient milling- and turning-specific functions.

Digital Readout Features:

Both the DRO300 & DRO203 have the same powerful basic features, providing better accuracy, less waste & better production times. They pay for themselves. 

ACU-RITE® provides a ROI calculator so that you can see for yourself!

Turning-specific features

  • Lock axis feature

  • Instant radius/diameter conversion

  • Taper calculator

  • CSS (option)


Dynamic zoom

  • The currently moving axis can be geographically highlighted.

  • In “dynamic zoom” mode, the position value is zoomed to its maximum size depending on the number of digits.

  • This greatly improves legibility—especially from a great distance. Click here to see Dynamic Zoom in action.

Milling-specific features

  • Bolt hole pattern calculations with graphics (full and partial circles/linear patterns)

  • Centerline calculation enables you to establish workpiece zero and midpoints

  • Edge finder input

  • I/O (option)

Day/night switching

 Depending on the ambient-light conditions at the machine, you can switch the screen of the DRO300 to a light or dark background.


Installation Guide is included in the program, walking you through the set-up.

ACU-RITE makes it easy to purchase replacement parts for your system. From the SENC 150, SENC 50 or just the display you can purchase these separately.

ACU-RITE -SENC-150-header-min

What is the difference between the SENC 150 and SENC 50?

The SENC 150 and SENC 50 linear encoders are very similar.

The SENC 150 is available in a wider range of measuring lengths, 75mm-3,075mm vs. 25mm-500mm. 

The SENC 150 from ACU-RITE is the ideal scale for all applications. The compact and robust design, and the numerous possibilities for mounting, make it ideal for retrofitting. The slight dimensions and high accuracies of this ball-bearing guided encoder, which uses the reflected light method, are ideal prerequisites that can be used in metrology applications.

  • Robust design

  • Resolutions from 0.5 µm to 5 µm

  • Output signals: TTL

  • Measuring lengths from 75 mm/2" to 3075 mm/120"

  • Distance-coded reference marks

  • The SENC 150 also has a slightly more rugged body, with a weight of 0.7 kg/meter of measuring length compared to 0.3 kg/meter.

The SENC 50 is extremely compact for when installation space is limited or restricted.

  • Compact dimensions

  • Resolutions from 0.5 µm to 5 µm

  • Output signals: TTL

  • Measuring lengths from 25mm/1" to 500mm/20"

  • Distance-coded reference marks

LMF 9310

LMF 9310

The LMF 9310 Multi-Section Inductive Encoder is a guided measuring system that uses an LMK scanning head with TTL incremental signals and an inductive measuring tape clamped on an integrated guiderail. 

 When properly installed to specifications, this encoder has an Ingress Protection Rating of 67 (IP67), leaving this measurement system virtually unaffected by environmental contaminants (i.e. oil, coolant, etc.).

With the incorporation of the included mounting coupling on the scanning head, high mounting tolerances can be realized—especially for longer measuring lengths.

Durable, dependable and affordable all-in-one package. 

LMF 9310 Features:

  • It comes available in lengths from 3,150mm (124") to 18,270mm (7") increments.


  • Accuracy Grade: ±20µ.


  • Distance Coded Reference Marks


  • 5v Incremental TTL Signals.
