The ISUDB60-18GM75 Series Ultrasonic Double Sheet Sensor is a precision industrial instrument designed to prevent damage and downtime caused by double-feeding in automated machinery. Housed in a standard M18 threaded nickel-plated brass casing, this sensor utilizes high-frequency ultrasonic waves to penetrate materials and analyze energy attenuation. Unlike optical sensors, the sensor is immune to ink dust, ambient light, and material color, making it the ideal solution for processing black paper, transparent films, and reflective metal sheets.

Engineered for versatility, the ISUDB60-18GM75 offers multiple output configurations (NPN/PNP, NO/NC) to integrate seamlessly with any PLC system. It features built-in LED indicators for immediate visual status feedback (Air/Single/Double) and short-circuit protection. Whether you are handling thin papers in offset printing or complex PCBs in electronics assembly, the sensor provides the reliability required for zero-defect manufacturing. Its Teach-in input allows for custom sensitivity adjustments, ensuring precise detection even with challenging materials like multi-layer cardboard or solar battery plates.

Typical Applications

double sheet detection sensor-ISUDB60-18GM75

In the commercial printing industry, the accidental feeding of two sheets (a "double feed") into the grippers and cylinders can cause catastrophic damage to the rubber blanket and mechanical gears, leading to expensive repairs and significant downtime. How the ISUDB60-18GM75 Solves This: The ISUDB60-18GM75 Ultrasonic Double Sheet Sensor is mounted at the feeder section of the press. As paper passes between the transmitter and receiver: Single Sheet: The sensor detects a specific level of sound wave attenuation and signals the machine to continue. Double Sheet: If two sheets stick together (due to static or humidity), the air pocket between them blocks the sound waves. The sensor detects this drastic signal drop within milliseconds (approx. 52ms for double) and triggers an immediate emergency stop or activates a diversion gate to eject the double sheet. Why it's better: Unlike capacitive or optical sensors, the sensor works perfectly on foil-stamped paper, dark/black cardstock, and clear plastic substrates, ensuring continuous operation regardless of the print job substrate.
