Pro-Range XKC-Y27C-NPN-DC 5-24V-D6mm Non-Contact Liquid Level Sensor

The Pro-Range XKC-Y27C-NPN sensor operates on a wide DC voltage range from 5V to 24V. This flexibility allows it to be powered directly from common industrial power supplies, PLC auxiliary outputs, or regulated DC sources without requiring an additional voltage regulator.

The sensor uses a capacitive sensing principle. It detects changes in capacitance caused by the presence of a liquid (dielectric) behind a non-metallic barrier. It can sense through materials like plastic, glass, or fiberglass up to 6mm thick, but it cannot detect through conductive materials like metal.

This sensor provides an NPN open-collector output. The output transistor sinks current to ground when liquid is detected. To interface it, connect the output wire to your PLC's digital input or microcontroller pin, with a pull-up resistor to the positive logic voltage (e.g., 5V or 24V). The Brown wire is typically V+, Blue is GND, and Black is the signal output.

Yes, with its IP67 rating, the sensor is dust-tight and can withstand temporary immersion in water up to 1 meter for 30 minutes. This makes it suitable for outdoor installations, washdown areas, and other harsh, wet industrial environments where moisture exposure is a concern.

Yes, the sensor features an adjustable sensitivity potentiometer. This allows you to fine-tune the detection threshold to account for variations in container wall thickness, material type (plastic vs. glass), and the dielectric properties of the specific liquid being monitored, ensuring reliable operation across different setups.
