The digital output cannot be connected to other sensor outputs (e.g., multiple sensor outputs must not be connected in parallel). Parallel connection may damage the sensor output loop.
Warn:
The sensor is not suitable for washdown or hazardous environments; In practical applications, it is recommended to use an independent enclosure device with appropriate specifications
The SK5030-NP-S12 sensor combines a small spot size and a fast response to achieve high-speed contrast detection. The SK5030 is capable of effectively detecting contrast differences between multiple colors on a variety of surfaces in the range of 50 gray levels. The SK5030 has a dimmed white light source that can be focused into 2.5-3mm2.5-3 \mathrm{~mm} a spot and directed at the target. The diffuse light returned to the sensor is measured. When its level is equal to or exceeds the threshold, the digital output will change state. Due to its fast response time, the sensor is suitable for high-speed applications. The sensor provides a digital output that automatically configures NPN and PNP. A PLC or computer can be used to monitor the status of a digital output signal.
Demonstration of use
MARK and BKGD are the two buttons provided to set the sensor detection level. When a mark is detected, the sensor output is activated. The marker may be lighter or darker than the background. To set up a sensor, follow these steps:
Place the marker or background on the sensor spot and press the appropriate button. A flashing red LED light indicates that the MARK setup is proceeding, and a flashing green LED light indicates that the BKGD setup is proceeding.
Place another marker or background on the sensor spot and press the appropriate button. The red/green LEDs flashing at the same time indicate a lack of contrast error. Repeat from step 1.
Verify that the red LED light flashes to indicate that the marker is present.

Multi-color targets
The marker is brighter than the background:
Plan the marker (e.g., white), followed by the brightest, closest grayscale color as the background (e.g., red). The threshold will be set between white and red, and it will only be triggered if white is present. The marker is darker than the background:
The schedule is marked as dark (for example, black) and the schedule background is the closest grayscale color (for example, brown), and the threshold is set between the two colors. Installation
Place the sensor approximately 28 mm away from the target (measured from the surface of the sensor lens). The sensor is usually placed at an angle of 15-20ᄋ to prevent reflective interference. When using a sensor to detect the gloss characteristics of a target, the sensor needs to be positioned perpendicular to the target. Connect the cables to the power supply and output as required.
Do not use other cables without verifying the connection and wire color, as this may damage the sensor. Controls
Output LED light
When working normally, the red LED light indicates the marker, and the green LED light indicates the background. A red-green LED light indicates that a MARK or BKGD reading has been taken.
MARK key
Set the tag level. After the measurement marker, the green LED may flash to indicate that the background needs to be measured.
BKGD key
Set the background level. After measuring the background, the red LED may flash to indicate that a measurement mark is required.
Output signal
Digital output
The digital output is the result of the configuration of the PNP/NPN, and the user can provide a load on this output to pull the output up to VDC or down to ground. The sensor monitor at this level automatically decides whether or not to operate the PNP/NPN drive. This output is typically connected to a PLC. As long as the sensor's yellow LED indicates that a mark is recognized, the output will remain active.
Analog output
The analog output is , 0-5V0-5 \mathrm{~V} with a resolution of 20 mV (8 bits). Any standard analog input channel is typically available on the PLC and may monitor this output. Analog output signals are useful in applications where thresholds are simple and triggers are insufficient. For example, continuous real-time intensity monitoring in the process allows small fluctuations or trends to be detected and red positive measures to be taken against them. The analog output response time is slower than the digital output response time and should be evaluated according to the requirements of each application.
