Mastering the
RGB Contrast Logic
Unlike standard monochromatic sensors, XSZ color mark sensors utilize an automatic RGB emission system. The sensor evaluates the reflection of Red, Green, and Blue light on the target material and background, instantly selecting the color that provides the highest contrast.
Dynamic Color Compensation
Seamlessly detects subtle color differences even on low-contrast materials like yellow marks on white films or light-colored labels on metallic foils.
50μs Response Latency
Powered by a high-speed micro-processor, the sensor completes the sensing-to-output cycle in 50 microseconds, supporting line speeds exceeding 800m/min.

What Our Global Partners Say
From high-speed bottling to precision flexible packaging, XSZ color mark sensors are the industry benchmark for stability and contrast intelligence.
"The 50μs response speed is real. We integrated these into our 800bpm packaging line and the registration accuracy is flawless. No more missed cuts or signal lag, even during high-speed production peaks."
"Detecting light yellow marks on white PET was impossible for our old sensors. XSZ's Automatic RGB selection solved it instantly. It locks onto the highest contrast spectrum without manual adjustment. Truly impressive tech."
"The Smart Teach-in logic works perfectly on metallic foils and glossy surfaces where other sensors fail due to glare. Our changeover times were reduced by 30% thanks to the simple one-button calibration."
Frequently Asked Questions
Expert answers to the most common technical inquiries regarding our RGB contrast and color mark sensing solutions.
How does the sensor choose between Red, Green, and Blue light?
Our XSZ-C20 Series features an intelligent micro-processor that automatically evaluates the reflection levels of all three colors (RGB) during the teach-in process. It then locks onto the color that provides the maximum contrast ratio between the mark and the background, ensuring ultra-stable detection.
Can it reliably detect marks on metallic or high-gloss foils?
Yes. For shiny materials like aluminum foil or glossy PET, we recommend the XSZ-C30 series. These models utilize specialized anti-glare optics and polarized filtering to minimize specular reflection, preventing "blind spots" often caused by metallic backgrounds.
What is the "One-Button Teach-in" process?
Setup is simple: 1. Place the light spot on the background and press the button once. 2. Place the spot on the color mark and press again. The sensor's Smart Logic instantly calculates the optimal threshold. We also offer a "Dynamic Teach-in" mode for setup while the machine is running.
Is 50μs response time fast enough for my 800m/min production line?
Absolutely. A 50μs response time corresponds to a switching frequency of up to 20kHz. This allows for precise triggering even at line speeds of 800m/min, maintaining a jitter accuracy of less than ±0.1mm—ideal for high-speed vertical form fill seal (VFFS) machines.
