Features
- Color recognition capability: Equipped with a dedicated color probe, it can accurately identify more than 3,000 kinds of colors; fiber optic color sensor has a micro-color difference recognition function, supports triple 16-bit computing RGB for precise target recognition, and color signals are converted into 16-bit data in the receiver.
- Channels and storage: Adopting an 8-channel design, it can store 8 colors at one time and detect 4 colors simultaneously.
- Color sensor performance: Using a small-sized, high-power dedicated detection head with a composite structure. The transmitter uses optic fiber to generate a single light spot, reducing the volume of the sensor head and improving detection capability and stability. ATO color sensor has three built-in detection modes, suitable for various application scenarios.

Wiring Method

External Input Settings

Set Sensitivity via External Input (External Tuning)
- Activate the key lock function.
- Connect the pink wire to an external device, such as a switch or PLC.
- Short-circuit the pink wire as shown in the diagram; for each model, this is equivalent to pressing the SET (setting) button.

Select Database via External Input (In C/C+I Mode)
- Activate the key lock function.
- Connect the purple wire to an external device, such as a switch or PLC.
- Short-circuit the purple wire as shown in the diagram, so that each model switches the database from A to B. (When the input signal is ON, the database is set to B.)

External Input Shift Input (During Super I Mode Setting)
- Connect the purple wire to an external device, such as a switch or PLC.
- Short-circuit the purple wire as shown in the diagram to enable shift input for each model. (The rising edge of the input signal executes the shift input.)
Tips: How to Select Correct Mode for Fiber Optic Color Sensor?
When using fiber optical color sensor, selecting the correct detection mode is crucial for ensuring accurate detection. The sensor has three built-in modes: C, CI, and SUPER I, each with its own characteristics, and the selection needs to be based on the detection requirements.
- C mode: If it is necessary to deal with scenarios where workpieces are moving or vibrating, and there is no need to distinguish neutral colors such as white, black, or gray, the C mode (RGB comparison) is a suitable choice, as it performs well in such scenarios.
- CI mode: When there is a need to detect subtle differences in colors, with low requirements for distinguishing neutral colors and acceptable influence from workpiece vibration, the CI mode (RGB comparison+light-dark comparison, receiving light brightness) can meet the needs and accurately capture tiny differences between colors.
- SUPER I mode: If there is a need to distinguish neutral colors (black and white) and the influence from workpiece vibration is acceptable, the SUPER I mode (light-dark comparison, receiving light brightness) is more applicable, as it can effectively identify neutral colors.
In summary, the correct detection mode for the color sensor can be selected based on the requirements for distinguishing neutral colors, and whether the workpiece has vibration and movement.
