Data Sheet MEM 25 IE cable www.pwb-encoders.com precision works better Description The MEM 25 is a magnetic incremental encoder. He is a reliable 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 25 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 and one index channel (one pulse per revolution)....

One Cycle (C): 360 electrical degrees (°e), one period of the signal. Cycle Error (ΔC): The deviation in electrical degrees of the pulse width from its ideal value. It is an indication of cycle uniformity. Pulse Width (P): The number of electrical degrees when an output is “HIGH” during one cycle, nominally 180 °e or half a cycle. Pulse Width Error...
