The Parallel Index uses a parallel cam mechanism, with parallel input and output shafts. Because it is easy to produce drives with 1,2, 3 or any small number of stops, the P series is the ideal indexing unit with relatively long dwell periods, such as occur on conveyers with long feed pitches. The design restrictions have been eased by employing Sankyo's original uneven-pitch parallel cams, so that now you can produce drives that used to be technically impossible.
