Your trusted Chinese color marker sensor manufacturer
Delivering industrial-grade precision, factory-direct pricing, and global support since 2015.
Factory Direct & Custom Engineering
Our R&D team specializes in RGB tricolor source technology and high-speed processing algorithms to ensure superior detection on challenging materials like metallic foils and transparent films. We offer flexible customization for light spot size, response frequency, and output modes (NPN/PNP) to perfectly integrate with your specific VFFS or labeling machinery.
Rigorous Quality Control Standards
Every color mark sensor undergoes strict testing protocols, including contrast sensitivity calibration, “teach-in” function verification, and high-speed response testing before shipment. We strictly enforce ISO 9001 standards to guarantee durability against machine vibration, paper dust accumulation, and temperature fluctuations in harsh packaging environments.
Expert Application Support & Rapid Replacement
In high-speed packaging, a sensor failure means costly downtime and material waste. We provide a 2-year warranty and direct access to engineers who can guide you through complex contrast “teach-in” settings on metallic foils or transparent films. We keep a massive stock of standard RGB models ready for immediate DHL/FedEx dispatch to ensure your production line never stops.
Free Sample Qualification Program
Not sure about detection stability on your specific films? Request a free sample to test on your packaging lines before bulk ordering
Step 1: Submit Requirements
Send us your current sensor model (e.g., Datalogic/Sick) or describe your packaging material (e.g., aluminum foil, transparent film). Our engineers will select the ideal RGB model for you.
Step 2: Same-Day Dispatch
We keep ample stock of standard RGB sensors. Once confirmed, we dispatch the test units within 24 hours via DHL/FedEx to ensure you get them fast.
Step 3: On-Site Validation
Install the sensor on your VFFS or printing machine. Verify the "teach-in" ease, spot alignment, and detection stability directly on your production line with zero risk.
Massive Inventory & Secure Global Shipping
"We maintain a ready stock of over 50,000 standard sensors to meet urgent maintenance needs. Every switch is individually packed in anti-static (ESD) bags and reinforced cartons to ensure zero damage during air or sea transit."

FAQ
Can your color mark sensor replace Datalogic TL46 or Sick KT5 sensors?
Yes, absolutely. Our sensors feature industry-standard mounting dimensions and wiring definitions. They are designed as a drop-in replacement for major brands like Datalogic, Sick, and Omron, offering the same (or better) performance at a more competitive price.
Can it detect low-contrast marks, like yellow marks on a white background?
Yes. Our sensors utilize RGB Tricolor Light Source technology. The sensor automatically selects the optimal light color (Red, Green, or Blue) during the “teach-in” process to maximize the contrast between the mark and the background, ensuring stable detection even for difficult color combinations.
Does it work on reflective materials like aluminum foil or metallic film?
Yes. We have specific models optimized for highly reflective surfaces. By adjusting the angle and using our advanced jitter-suppression algorithm, our sensors can reliably distinguish registration marks on shiny metallic foils used in coffee or snack packaging.
How do I set up the sensor? Is it complicated?
It is very simple. Our sensors feature a “One-Touch Teach” button.
Align the light spot with the background -> Press button.
Align with the color mark -> Press button. The sensor automatically sets the threshold. We also provide a video tutorial to guide you.
Do I need to choose between NPN and PNP?
Most of our standard models feature NPN/PNP switchable output or distinct models for each. Please specify your requirement when ordering, or ask our engineers if you are unsure about your PLC compatibility.
What is your warranty policy?
We offer a 2-Year Warranty on all color mark sensors. If any quality issue arises (excluding human damage), we will provide a free replacement immediately to ensure your production is not affected.
