An ultrasonic single/double sheet detection sensor is an industrial sensor specifically designed for use in automated equipment to prevent two or more sheets of material (such as paper, film, or metal sheet) from overlapping and entering the machine. It uses ultrasonic waves generated by high-frequency oscillations to penetrate the material and accurately distinguishes between "no sheet," "single sheet," or "double sheet/overlapping" states based on the degree of signal attenuation.
Main Features:
❏ Features memory learning function, easily switching between handling paper, thick and thin films, silicon wafers, and thin boards.
❏ Unaffected by material color, transparency, or surface texture, it can detect various materials such as paper, plastic film, metal foil, leather, and non-woven fabric, solving the problem of inaccurate detection of transparent/dark materials by photoelectric sensors.
❏ Built-in intelligent chip, unaffected by environmental interference, accurately detects objects, operates stably, safely, and reliably without interference.
❏ Unaffected by object color/transparency, gloss, or ambient light.
❏ No contact with the material surface, avoiding scratches on fragile materials such as paper, film, and metal foil, and preventing friction from affecting material conveying speed.
Common Application Scenarios：
Printing and Paper Manufacturing: Preventing double sheets from being fed into offset printing presses, which could cause paper jams or printing errors.
Packaging Industry: Detecting whether cardboard boxes or instruction manuals are being fed in overlapping order.
Battery Manufacturing: Monitoring the feeding process of electrode foils.
Photovoltaics and Semiconductors: Detecting single or double wafers during silicon wafer handling.
