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, PLCs,
robot controls, CNCs, and industrial computers.
The EC23 is mechanically interchangeable with the all
popular Size 23 encoders.

Applications:
The Series EC23 is a high resolution, optical incremental
encoder designed for light industrial and commercial
applications. A standard Size 23 (2.3" dia.), the EC23 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.
