Pro-Range XKC-Y28A-NC-DC 12V Non-Contact Liquid Level Sensor

The XKC-Y28A-NC series typically provides a digital switching output. Common configurations include an NPN (sinking) or PNP (sourcing) transistor output, or a relay contact closure. The specific output type should be confirmed from the sensor's label or datasheet for proper integration with your PLC or controller input module.

No, it is specifically designed for non-metallic containers. It works optimally with insulating materials like glass, plastic (PVC, PE, PP), ceramic, or fiberglass. It will not function correctly through conductive materials like metal, as they shield the capacitive field. The container wall thickness and material density affect the sensing range and require sensitivity adjustment.

The sensor features an integrated potentiometer, usually accessible through a small hole in the housing. Using a small screwdriver, you can adjust the detection threshold. Turn it clockwise to increase sensitivity for thicker walls or lower dielectric liquids, and counter-clockwise to decrease sensitivity to prevent false triggers from external interference or thin walls.

The effective sensing distance depends on the container material and liquid properties. For typical plastics like PVC or polyethylene, the practical range is usually up to 10-15 mm. For glass, it may be less. Always refer to the manufacturer's technical sheet for specific limits and perform a bench test with your actual container for verification.

Yes, its non-contact design inherently protects the sensing electronics from the liquid. Combined with its IP67-rated, corrosion-resistant housing, it is well-suited for monitoring aggressive chemicals, acids, bases, and sanitary fluids, as long as the container itself is compatible with the liquid.
