Overview / Design Principle:
A pre-wired cable or terminal screw connections
are included with either servo clip or face mounting
options.
Its bidirectional and optional marker pulse, current
sink or differential line driver outputs are compatible
with most electronic counters, instruments, PLC’s,
robot controls, CNC’s, and industrial computers. The
E23 is mechanically interchangeable with other Size
23 encoders on the market.

Applications:
The Series E23 is a high resolution, optical incremental
encoder designed for light industrial and commercial
applications. A standard Size 23 (2.3" dia.), the
E23 is ideal for machine and equipment designs with
limited space and high performance requirements.
Typical Applications:
* Motor mounted feedback for servo systems
* Assembly machines
* Robotics and material handling
* Printers, X/Y plotters, and phototypesetters
* Semiconductor I.C. bonders
* Medical diagnostic equipment (X-ray & CAT scanners)
* Position and/or velocity input for CNCs, PLCs,
motion controllers, etc.
