Overview / Design Principle:

The Series 21/22 QUBE generates digital incremental position data proportional to shaft rotation. Through higher mechanical and electronic operating speeds, the Series 21/22 QUBE heavy duty encoders can boost system speeds, cycle times, and productivity.

Its general-purpose design makes the Series 21/22 QUBE incremental encoders compatible with most programmable controllers, electronic counters, motion controllers, and motor drives. The Series 21/22 QUBE is electrically and physically interchangeable with most cube-style encoders on the market. It can easily be applied with belts and pulleys, leadscrews, rack and pinions, lineshafts, etc..
