Time and money saver--linear protected or angular Gear Rack & Pinion Measuring System requires little or no maintenance!

rack_and_pinion_encoder.gif (6331 bytes)

Rack and Pinion style incremental linear optical encoder or resolver combined with a ruggedly constructed DRO or CNC provides the user with years of trouble-free operation.  Here are six major reasons why the Relinace/SEL Series Precision Rack and Pinion measuring system is better than the one with glass scales:

Can be used for either linear or angular measurement
The protected rack channel enclosure keeps the debris out while assuring better than .0005"/80" accuracy and repeatability better than .000050"
