Height control for tray stacks and printed circuit boards

A gripper arm removes the top tray from the tray stack and lifts it into an intermediate position before the printed circuit boards are fed to the assembly line. To ensure that the gripping arm grasps the right part of the printed circuit board, the OD Mini short-range distance sensor detects the height of the tray stack using distance measurement technology. The sensor then transmits the measured data to the pallet handling machine control.
