The model R22 is a size 20 encoder that is a compact 2" diameter x 1-7/8" (Ø51mm x 48mm) long optical shaft encoder with an integral mounting arm, compatible with a variety of mounting accessories for installation either above or below a moving web or conveyor. When used with the MW-8 (8.00" circumference) or MW-20 (20.00cm circumference) measuring wheel it can accurately track the web or conveyor to within ±.007" or ±.016cm per revolution.

Solid construction and heavy duty bearings make this encoder a great choice for long-term operation in continuous duty applications.

Features and Options:

  • Accurate linear measurement
  • Dual precision measuring wheels
  • Compact size 20
  • "Anti-Jitter" and other material handling features
  • IP66 optional
  • USAMade in the USA

Electrical

 

Supply Voltages: (specify when ordering)
          5 VDC or 8-30 VDC

Current:

  • 50 ma max (no load)
  • 100 ma max (differential line driver)

Pulse Rate: 0 - 30 kHz

Counts per Revolution: (specify when ordering)
          1 to 2400

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 line driver
      (also with optional 5vdc output level)

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 output A or B. Output A leads B by 90° for clockwise rotation viewed from shaft end farthest from the connector.

  • Pulse symmetry: 180°±30%
  • Pulse interval jitter: 30% max
  • Quadrature: 90°±30% max
  • Phase jitter: 30% max

Anti-jitter: (single output models only) Increases pulse hysteresis to ½ of a pulse width, eliminating the effects of mechanical vibration and possible false output pulses. For example a 10 pulses per revolution output has 18° hysteresis (i.e. 360° ÷ 10 × ½).
