Wiring Method

Q1: What are the main functions of this Digital Color Recognition Sensor?
A1: It supports two switchable modes. In color mode, the RGB color sensor uses simultaneous RGB three-color light to judge color with high precision based on the reflected R/G/B ratio. In mark mode, it automatically selects a suitable single color from RGB, working as a color mark sensor for high-speed detection. The ON button sets the target color, while the OFF button sets the background color. Threshold hysteresis is adjustable to small, medium, or large to reduce jitter.

Q2: How does this industrial color sensor ensure reliable performance in automation?
A2: It offers 18–28mm detection distance and < 100 μs response time, suitable for high-speed lines. The 1.5×7mm rectangular spot ensures accurate positioning for small marks and color recognition. It supports 12–24VDC supply, NPN/PNP output, built-in short-circuit protection, and strong anti-interference for PLC connection. A 4-core rubber cable with a 2 m standard length is included for easy wiring.

Q3: What should I know before using this color detection sensor?
A3: Mode switching is done via the mode switch wire, and the status indicator shows the current working mode. Press ON to set the target color and OFF to set the background color; detection is ready after setup. The compact ABS housing measures 50×32×21mm and operates from -10°C to 55°C. When detection is unstable, adjusting the sensor tilt angle can further optimize performance.

Tips: What is the correct setup procedure for this digital color recognition sensor for both color and mark detection?

• Mode selection comes first. Use the mode switch wire to toggle between color mode and mark mode; the status indicator shows which mode the color detection sensor is currently in.
• For color mode, the RGB color sensor emits three colors simultaneously. Press ON to set the target color, then press OFF to set the background color—high-precision discrimination follows automatically.
• For mark mode, the industrial color sensor automatically picks a suitable single color from RGB. This makes the color mark sensor ideal for high-speed detection of printed marks or labels.
• Threshold hysteresis can be set to small, medium, or large. Adjusting it properly prevents false triggers caused by object jitter during conveyor or production line operation.
• Installation angle matters. If detection becomes unstable, tilt the sensor slightly to optimize light reflection. Keep the 1.5×7mm rectangular spot within the 18–28mm range for accurate positioning.
• Wiring check: confirm a 12–24VDC supply and match NPN/PNP output to a PLC. The built-in short-circuit protection safeguards the digital color recognition sensor, but correct wiring minimizes interference.
