Pro-Range XKC-Y26-V-DC 5-24V Non-Contact Liquid Level Sensor

The sensor operates on a wide DC voltage range of 5 to 24 volts. This makes it compatible with common microcontroller power rails (5V), industrial PLC digital inputs (24V), and various DC power supplies within that range without requiring additional regulation.

The sensor uses capacitive or high-frequency sensing principles to detect the presence of liquid through the dielectric material of a container wall. It is designed specifically for non-metallic containers such as plastic (PVC, PP, PE), glass, and ceramics. It cannot detect through conductive metal walls.

The sensor provides a simple digital switch output (typically a high/low logic signal or an open-collector output). Wiring generally involves connecting the red wire to the positive DC supply (5-24V), the black wire to ground, and the signal wire (often blue or yellow) to your controller's digital input pin to read the liquid state (present/absent).

This model is primarily a point-level detection sensor. It provides a binary output (on/off) when liquid reaches the specific point where the probe is mounted. For continuous level measurement, you would need to install multiple sensors at different heights or use a different technology like an ultrasonic or pressure sensor.

Yes, its non-contact design is a key advantage for corrosive media. Since the sensing element does not directly contact the liquid, it is protected from chemical attack, making it ideal for monitoring strong acids, alkalis, solvents, and other aggressive substances contained within compatible non-metallic vessels.
