Stack positioning

OD Value or Dx50 distance sensors continuously measure the side position of the paper stack while it is moving into the target position. The Ax20 analog array sensor can measure the height of the stack. If the height of the paper stack is to be detected at only one point, W9-3, W12-3 or W18-3 small photoelectric sensors that supply a digital switching signal provide the optimal solution.
