Designed for high-speed industrial environments, this sensor utilizes advanced 300kHz ultrasonic technology to distinguish between empty, single, and double sheets with unmatched reliability.
Whether you are handling transparent films, paper, metal foils, or lithium battery electrode sheets, this sensor eliminates the risk of machine downtime caused by multi-layer feeds.
Why Choose High-Frequency 300kHz Technology?
Unlike standard proximity sensors, our 300kHz ultrasonic system uses a through-beam principle that measures the attenuation of sound waves passing through the material.
Material Independence: It is unaffected by color, transparency, or surface gloss. Even highly reflective metal foils or dark black papers are detected consistently.
High Penetration: The optimized frequency ensures penetration through thicker cardboards while maintaining sensitivity for thin plastic films.
Key Features & Technical Advantages
Versatile Material Handling: Perfectly calibrated for paper, cardboard, plastic films, and critical Lithium battery electrode sheets.
Universal Compatibility: Features switchable output modes (NPN/PNP, Normally Open/Normally Closed) to integrate seamlessly with any PLC or industrial control system.
M12 Robust Housing: Standard industrial M12 threading allows for easy mounting and replacement in tight machinery spaces.
Intelligent Feedback: Real-time identification of three states:
Air (Empty): No sheet present.
Single Sheet: Normal operation.
Double Sheet/Splice: Fault condition triggering immediate output.
Industrial Applications
This ultrasonic double sheet sensor is the preferred safeguard for:
Printing & Packaging: Preventing multi-feed jams in offset printing and labeling machines.
Battery Manufacturing: Detecting double layers in cathode/anode stacking and winding processes.
Automated Logistics: Verifying document presence and preventing overlaps in sorting systems.
Converting Machinery: Identifying splices in roll-to-roll metal film slitting.

Typical Applications
The M12 double-sheet detection sensor can accurately detect the presence of double or multiple sheets being fed together during the paper delivery process. By monitoring changes in paper thickness or optical signals in real time, it can immediately output a control signal when an anomaly is detected, triggering an alarm or stopping the machine, thereby effectively avoiding paper jams, printing errors, and equipment damage.
