200kHz Ultrasonic Transducer | Edge Control & Web Guiding Sensor
200kHz High Frequency, Edge Detection, Web Guiding, Transparent Film Detection, Coil Alignment, Narrow Beam Probe, Industrial Automation, Ultrasonic Transceiver
Engineered for the demanding precision of industrial automation, the ISU200-18.6TRBZ is a high-performance 200kHz Ultrasonic Transducer designed specifically for edge detection and web guiding systems. Unlike optical sensors that struggle with transparent or reflective materials, this high-frequency probe utilizes sound waves to accurately track the edge position of any material—be it clear plastic film, shiny lithium battery electrode sheets, or black rubber belts. Its 200kHz operating frequency generates a focused, short-wavelength signal with a narrow 10∘10∘ beam, enabling sub-millimeter positional accuracy while minimizing interference from surrounding machinery. Housed in a durable aluminum casing, it offers the robustness needed for continuous operation in coil processing and converting lines. (Note: This is a transducer component requiring an external drive circuit).

Typical Applications
This transducer is the critical sensing element for "Web Guiding Systems" (EPC/LPC) across various manufacturing sectors. It is widely used in the lithium battery industry to detect the edges of electrode sheets (cathode/anode) and separators during coating and winding processes. In the packaging and printing industry, it provides precise alignment for transparent films and paper webs where photoelectric sensors often fail. Additionally, it serves as a reliable edge correction sensor for rubber tire manufacturing and metal coil slitting lines, ensuring materials remain perfectly centered or aligned during high-speed processing.
