The dbk+4/M12/3CDD/M18-E+S is a Microsonic ultrasonic double sheet detector for reliable detection of double sheets, missing sheets, and single-sheet conditions in paper, film, metal-laminated materials, fine corrugated board, and similar web or sheet-fed materials. This version uses compact M12 sensing heads for cramped installation spaces, offers a 20–40 mm sensor spacing range with 20 mm optimal spacing, and provides 2 x PNP NO/NC outputs for independent double-sheet and missing-sheet signals.
It is used in OEM machinery, packaging equipment, print and converting systems, and other automation applications where dependable sheet separation monitoring is required. The sensor supports Teach-in programming, LinkControl configuration, and fast response for demanding industrial use.
