Description


OETAI GDS-C21W Color Mark Sensor - Precision Color Tracking & Mark Detection

The OETAI GDS-C21W Color Mark Sensor provides precise color tracking and mark detection for industrial automation and quality control.

The OETAI GDS-C21W Color Mark Sensor is designed for precise color tracking and mark detection. It offers accurate color measurement and reliable mark recognition, making it ideal for industrial automation and quality control applications. Its robust design ensures durability and long-lasting performance.

OETAI GDS-C21W High-Precision Color Mark Sensor

The OETAI GDS-C21W is a flagship photoelectric sensor engineered for high-speed color mark detection in packaging and printing industries. Featuring advanced optical processing, it identifies subtle color contrasts on various substrates—including high-gloss films and metallic foils. This precision sensor ensures millisecond-accurate positioning for cutting, folding, and sorting, significantly reducing waste in high-volume production lines.

Technical Specifications

Parameter Specification
Model GDS-C21W
Detection Method Diffuse Reflective (Coaxial)
Supply Voltage 10-30V DC
Output Type NPN / PNP (Model Dependent)
Response Time < 0.5ms

Application & Industrial Value

The GDS-C21W utilizes a coaxial optical system which eliminates sensitivity to material shaking, making it ideal for Vertical Form Fill Seal (VFFS) machines. By accurately detecting registration marks on moving webs, it enables PLC systems to synchronize cutting tools with sub-millimeter precision. Its IP67-rated housing ensures reliability in dust-heavy environments like flour packaging or chemical processing plants.

Troubleshooting & Maintenance

Q1: The sensor is outputting erratic signals even without a mark.
A: This is often caused by material flutter or gloss reflection. Ensure the sensor is mounted at a slight angle (approx. 10-15°) relative to the perpendicular surface if the material is highly reflective (like aluminum foil) to avoid specular glare.

Q2: How do I switch between Light-ON and Dark-ON?
A: The GDS-C21W typically features a control wire (white or pink) for mode selection. Connecting this wire to VCC or GND will toggle the output logic. Reference your specific wiring diagram to ensure the signal matches your PLC's logic (Normally Open/Closed).

Q3: The sensitivity button (Teach-in) is not responding.
A: Ensure the sensor is within the 10-15mm optimal focal range. If the distance is too far, the optical feedback will be too weak for the internal processor to complete the "Teach" cycle. Clean the lens with a soft, lint-free cloth.
