ISUDB60-18GM75
Ultrasonic Double Sheet Sensor | Multi-Material Detection for Automation
Ultrasonic Double Sheet Sensor, Non-contact Double Feed Detection, PCB Loading Sensor, Ultrasonic Through-beam Sensor, Double Sheet Monitor, Packaging Automation Sensor, Clear Object Detection
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.
