Product Recommendation | UDC Series Ultrasonic Sensors for Single/Double Sheet Detection – Clearly Identify No Material, Single Sheet, or Stacked Sheets at a glance

Are you tired of dealing with traditional detection methods? Are you experiencing any of the following issues:

Photoelectric sensors failing when detecting transparent, reflective, or dark-colored materials?

Mechanical probes having a high misjudgment rate when two thin sheets are tightly attached with minimal thickness difference?

Optical windows getting contaminated in oily, dusty environments, leading to frequent false triggers?

Frequent parameter adjustments required for different materials/grammages, resulting in production line shutdowns during model changes?

The UDC Series ultrasonic sensors for single/double sheet detection completely solve the above pain points. Whether you are detecting 10g/m² thin paper, 2000g/m² cardboard, plastic films, or metal foils – ultrasonic waves penetrate the medium to reach the essence, eliminating material-related concerns in thickness detection once and for all!

【  Product Features  】

• Applied in printing machines: The ultrasonic double-sheet detection prevents accidental feeding of two sheets that may damage precision mechanical structures, or ensures no second sheet remains inside the machine.
• An ultrasonic system for reliable detection of no material, single sheet, double sheets, or stacked materials.
• Strong anti-interference capability: Enhanced resistance to electromagnetic and radio frequency interference.
• Equipped with short-circuit protection and power memory protection functions to effectively prevent circuit damage.
• Completely unaffected by dust, dirt, and mist.
• Detectable range covers materials from 10g/m² paper to 2000g/m² cardboard, plastic, or metal foils.
• With temperature compensation function, not affected by ambient temperature.
• Provides NPN and PNP switching output.
• Realizes self-learning function through multi-functional input; functions can be remotely set arbitrarily via cables.
• Detection range: 20-60mm, with an optimal value of 45mm.

By choosing Heyi UDC Series ultrasonic sensors for single/double sheet detection, you will gain four core value guarantees to improve production efficiency and quality:

Zero Missed Detection: Accurately identify double sheets and stacked materials, preventing double sheets from entering precision units. This fundamentally avoids mold damage and equipment shutdowns, reducing unexpected losses.

Zero False Alarms: Dual support of anti-electromagnetic interference and temperature adaptability ensures stable detection even under complex working conditions, eliminating the need for frequent handling of false triggers.

Zero Maintenance: Non-contact detection design with no wearable parts, and immunity to dust and oil pollution, significantly reducing equipment maintenance frequency and labor costs.

High Compatibility: A single device is compatible with paper, plastic, metal, and composite materials. Even when the production line is upgraded, there is no need to replace hardware, saving equipment investment costs for enterprises.

For enterprises pursuing efficient and stable production, Heyi UDC Series ultrasonic sensors for single/double sheet detection are more than just a detection device – they are a powerful tool to improve production efficiency and reduce operating costs.
