Data Sheet MEM 16 www.pwb-encoders.com precision works better Description The MEM 16 is a magnetic incremental encoder. He is a reliable low cost hollow shaft encoder that can be fixed quickly and easily on different sizes of motor shafts. The encoder is developed for brushless motors, motor feedback applications and rotational speed control. The MEM 16 is a real time system for high speed applications and rough environments. The encoder provides two square wave outputs in quadrature (90 degrees phase shifted) for counting and direction information. The resolution of the encoder is...

Data Sheet MEM 16 www.pwb-encoders.com precision works better Electrical interface Cable Wire color red yellow black purple 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...
