Mounting an magnetic, optical or inductive encoder directly
to the slider gives a direct reading of slider movement eliminating
lead screw and backlash errors.

New Velmex Digital Readout with optional base
The Velmex Read Out (VRO) is a compact one or two axes digital readout for linear and rotary incremental encoders. The VRO uses the latest OLED display and DSP microcontroller technology for high performance, ultra-precise, digital position readout. Designed for differential type encoders, the VRO is also fully compatible with single ended encoders.

Axis QC-100 Series DRO
|The USB to Serial
Adapter connects the DRO to a computer USB port. This
adapter will automatically be configured as a virtual COM serial
port on a PC. This virtual COM port works exactly the same as
a standard COM port allowing all software to address the DRO
directly through a COM port number. Use this adapter with a
computer with an available USB port, but no RS-232 (COM) serial
port. Catalog number 4-2132. User Manual Data sheet
encoder output can also be transmitted to a PC directly using
a PCI card like this one. It can read up to 4 encoders. We
do not sell this.
|Encoders have quadrature
output using 5 V logic and are stocked in the following resolutions:
100, 200, 400, and 500 counts per revolution (CPR). See

When combined with a DRO
readout, the encoder counts are converted to inches for the
English thread or centimeters for the metric thread lead screws.
For rotary tables, the encoder can be mounted on a motor
shaft extension. It will read degrees on the DRO. Data sheet

Linear resistor strip analog encoder
Alternatively, for units up to 20" travel,
a linear strip variable resistor can be installed paralleling the
ways of the UniSlide Assembly. These resistor strips are available
in lengths from 2" to 20" and are normally 1.5K ohms/inch.
Accuracy is within 0.25%.
