DIGITAL READOUTS

A complete system consists of one or more Linear Encoders, commonly referred to as scales, and a Digital Readout.
The Linear Encoder monitors the machine travel and the Digital Readout (DRO) displays the distance moved or machine table position to the operator.
The axis display is large and clear and the keyboard is designed to be easy to use.
Many functions can be taken off the keyboard to support the work at the machine.
Depending on application you can choose between different versions of the readout.
