Data Sheet MEHR 25 plug www.pwb-encoders.com precision works better Description The MEHR25 is a high resolution optical encoder. He is available as a shaft or hollow shaft encoder for different sizes of motor shafts. The encoder provides two differential square wave output signals (in quadrature 90 degrees phase shifted) for counting and direction information and one index channel (one pulse per revolution). The resolution of the encoder is determined by the number of counts per revolution (CPR). Power supply and signals are provided by a 8 pin Molex connector. Features Small size: 25.0 mm diameter...

Data Sheet MEHR 25 plug www.pwb-encoders.com precision works better Electrical interface Amplitude Definitions Channel 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...
