Overview Industry/Application Specifications Related Info  

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 encoder is mechanically interchangeable with other Size 23 encoders on the market.

Applications:

The Series E23 encoder is a high resolution, optical incremental encoder designed for light industrial and commercial applications. A standard Size 23 (2.3" dia.), E23 incremental encoders are 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 CNC’s, PLC’s, motion controllers, etc.
