Pro-Range XKC-Y28A-NO-DC 24V Non-Contact Liquid Level Sensor

The XKC-Y28A-NO-DC typically provides a digital output, often in the form of a Normally Open (NO) or Normally Closed (NC) relay contact or a transistor switch (NPN or PNP). This output changes state (on/off) when the liquid level reaches the detection point, making it directly compatible with PLC digital inputs, alarm circuits, and relay control modules for industrial automation.

No, this sensor is specifically designed for non-metallic containers such as plastic, glass, or fiberglass. The capacitive sensing principle requires the electric field to penetrate the container wall, which is blocked by conductive metal. For metal tanks, a different technology like ultrasonic, pressure, or contact-type level sensors would be required.

The sensor features an adjustable sensitivity potentiometer, usually located on the housing. To calibrate, mount the sensor on the empty container at the desired detection level and adjust the pot until the output LED indicator turns on. Then, fill the container to the detection point and fine-tune the setting for a reliable and stable trigger point, accounting for the specific wall material and liquid properties.

While the exact maximum thickness depends on the material's dielectric constant and the liquid being detected, typical non-contact capacitive sensors like this one are effective through plastic or glass walls up to approximately 10 mm thick. For best results and to ensure reliable detection, consult the sensor's datasheet for specific guidelines relative to your application's material and environmental conditions.
