Wheeled Encoder - R22 Series
R22 - Compact size and Rugged Construction
The model R22 is an optical shaft encoder in a 2" diameter x 1-7/8" (Ø51mm x 48mm) housing 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 wheels it can accurately track the web or conveyor to within ±.007" or ±.016cm per revolution. This is not a light duty encoder - it was built with heavy duty bearings and solid construction for reliable, long-term operation in continuous duty applications.
Standard Features and Options:
• Double ended shaft and integral mounting arm
• Unbreakable code disk
• Up to 1200 pulses per revolution
• Attached cable or optional connector
• Heavy duty bearings
• Short circuit and ESD protected

ELECTRICAL
- Supply Voltages: (specify when ordering)
5 VDC or 8-30 VDC
- Current: 50 mA max (no load)
100 mA max (line driver)
- Pulse Rate: 0 - 30 kHz
- Pulses per Revolution: (specify when ordering)
1 to 1200 (call for values up to 4800)
- 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)
- 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 B by 90° for clockwise rotation viewed from end by handle.
- Pulse symmetry: 180°±30%
- Pulse interval jitter: 30% max
- Quadrature: 90°±30% max
- Phase jitter: 30% max
- Anti-jitter: (single output models only) Increases the pulse hysteresis to ½ of a pulse width, eliminating the effects of mechanical vibration and possible false output pulses. For example a 10 pulse per revolution output has 18° hysteresis (i.e. 360° ÷ 10 × ½ ).
