Double Sheet Detectors monitor the the automatic sheet destacking/ sheet feed on sheet working machines to avoid demages on feeders machines, dies, tools etc. We deliver a wide range of different models for solving this task : For most kind of sheet materials, sheet thicknesses, sheet feeders, sheet destackers, robots etc. The double sheet sensors/- detectors have an signal output that can be used to repeat the sheet feed (shake off the double sheet) stopp the shett feed process, or to eject the double sheets. Furthermore to control otical and / or acoustical alarms or other machine operator service calls.
