dbk+4/M18/3CDD/M18-E+S, Microsonic Double Sheet Detector, 20 – 60 mm range, compact M18 sensing heads, 2 x PNP NO/NC outputs for double & missing sheet signals

The dbk+4/M18/3CDD/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 wafers. This version uses compact M18 sensing heads for cramped installation spaces, offers a 20–60 mm sensor spacing range with 40 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.
