Optic Shaft Encoder R20-P
Series 20-P with Heavy Duty Bearings

The model R20-P is an optical shaft encoder in a 2" diameter x 1-3/4" long housing that can be face mounted using three 6-32 x .25" deep mounting holes on a 1.75" diameter bolt circle. The shaft is up to 3/8" diameter, either single or double ended. Electrical connection is through a 16mm circular connector or an attached cable.
The encoder is factory configured with a program that offers one or more features. DIP switches are used to set program parameters. Examples of some of the available features are: selectable pulses per revolution, quadrature (A/B) outputs, direction output, and the anti-jitter feature.

ELECTRICAL 

• Programming Features: The encoder is factory configured with a program that offers one or more of the following features. DIP switches are used to set program parameters.
  • Selectable Pulses per revolution
  • Quadrature (A/B) outputs
  • Direction outputs
  • Anti-Jitter feature
  • Other enhanced features
• Supply Voltages: (specify when ordering)
            5 VDC or 8-30 VDC
• Current: 500 mA max (no load)
            100 mA max (line driver)
• Operating Temperature: 0° to 70° C
• Output Circuit: (specify when ordering)  
  Output voltage level is approximately the same as the input voltage level.
• Single Ended:
  • 7273 open collector (30 VDC max, 50 mA max)
  • 7272 Push-Pull (50 mA max source or sink)
• Differential Line Driver:
• 7272 differential line driver (also with optional 5vdc output level)
• Pulse symmetry: 180° +/- 30%
• Pulse interval jitter: 30% max
• Quadrature: 90° +/- 30% max
• Phase jitter: 30% max 
• Output Waveshape: 
  Square wave outputs A and B are 50/50 duty cycle nominal. Output Z (index output) is approximately the width of one cycle on outputs A or B. Output A leads by 90 for clockwise rotation when viewed from shaft end.
