Banner Engineering QS18VP6AF300 WORLD-BEAM Adjustable Field Background Suppression Sensor, 300mm Range, 10-30V DC, PNP Output, 2m Cable

In Light ON mode, the PNP output switches ON (provides voltage) when the sensor detects the target object (light is reflected). In Dark ON mode, the output switches ON when the target is absent (no light reflection). The mode is typically selected via a switch on the sensor body to match the required control logic of your PLC or controller.

The QS18VP6AF300 features an adjustable sensing field. Using a small screwdriver, turn the adjustment potentiometer located on the sensor while observing the output status LED. This allows you to set the precise cutoff distance, ensuring the sensor triggers only for objects within the desired range and ignores the background.

The standard 4-wire cable includes connections for Brown (+V DC), Blue (0V Common), Black (PNP Output), and White (Output Common). Connect Brown to your positive DC supply (10-30V), Blue to DC negative/ground, and the Black output wire to your PLC input or load. Always refer to the specific wiring diagram provided in the sensor's datasheet for your model.

Yes, the adjustable background suppression technology is particularly effective for detecting transparent, glossy, or highly reflective objects that can challenge standard diffuse sensors. By measuring the angle of reflection, it can reliably distinguish the target from the background, making it suitable for glass, plastic, and metallic surfaces.
