Data Sheet ME22-PU www.pwb-encoders.com precision works better Description The ME22 is a reliable low cost optical hollow shaft encoder that can be fixed quickly and easily on different sizes of motor shafts. The encoder provides two square wave outputs in quadrature (90 degrees phase shifted) for counting and direction information. The resolution of the encoder is determined by the number of counts per revolution (CPR). Power supply and signals are provided by a 5 pin Molex connector. Features Small size: 22.0 mm diameter x 21.9 mm length. Quick and easy assembly without touching sensitive components...

Data Sheet ME22-PU www.pwb-encoders.com precision works better Electrical interface Definitions Counts per Revolution (CPR): The number of bar and window pairs or increments per revolution of the code wheel. One Cycle (C): 360 electrical degrees (°e), one period of the signal, caused by one pair of bar and window. Pulse Width (P): The number of electrical degrees that an output is high during one cycle. This value is nominally 180 ºe. State Width (S): The number of electrical degrees between a transition in the output of channel A and the neighbouring transition in the output of channel B. There...
