Additional Details

The EC10E1220501 typically outputs two quadrature signals (A and B) that are 90 degrees out of phase. The direction of rotation can be determined by observing which signal leads the other. The resolution of the encoder (pulses per revolution or PPR) is a critical parameter that determines the precision of the rotational measurement. This parameter, along with the shaft dimensions, detent characteristics, and electrical specifications, can be found in the official ALPS Electric datasheet for the EC10E1220501.
