Wheeled Encoder - R22-P Series
R22-P - Compact size, Rugged Construction, User Selectable Parameters
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. During installation various features, such as the number of pulses per revolution, can be selected by setting configuration switches. The available features depend on the encoder model (see Currently Available Programs table)
Standard Features and Options:
• Double ended shaft and integral mounting arm
• Unbreakable code disk
• Various programmable features
• 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 ).
