This model operates from a wide DC 5V to 24V power supply and provides a high/low-level signal output. It is suitable for small plastic tubes, transparent pipes, water pipelines, liquid dispensing equipment, automatic filling systems, medical equipment, home appliances and industrial automation applications.
The internal signal-processing circuit detects this capacitance change and converts it into an electrical signal. When the capacitance variation exceeds the preset threshold, the sensor determines that liquid has reached the detection point and changes the high/low-level signal output.
The Brown VCC wire connects to the positive supply, the Blue GND wire connects to 0V, and the Black MODE wire is used to select the required output logic.
Always verify the relay operating voltage and current requirements before connecting it directly to the sensor output.

Description
XKC-Y26A-V Thin-Tube Non-Contact Liquid Level Sensor, 5-24V DC – Signal Output
The XKC-Y26A-V is a thin-tube non-contact capacitive liquid level sensor specially designed for detecting the presence of liquid inside small-diameter non-metallic pipes. The sensor is mounted externally around the pipe using its integrated spring-clip mechanism and detects liquid through the pipe wall without making direct contact with the liquid.This model operates from a wide DC 5V to 24V power supply and provides a high/low-level signal output. It is suitable for small plastic tubes, transparent pipes, water pipelines, liquid dispensing equipment, automatic filling systems, medical equipment, home appliances and industrial automation applications.

Working Principle
The XKC-Y26A-V operates using the capacitive sensing principle. When no liquid is close to the sensing area, the sensor maintains a certain static capacitance. When liquid inside the pipe reaches the sensing position, the liquid introduces additional parasitic capacitance.The internal signal-processing circuit detects this capacitance change and converts it into an electrical signal. When the capacitance variation exceeds the preset threshold, the sensor determines that liquid has reached the detection point and changes the high/low-level signal output.

- Ensure that the sensing section remains in close contact with the pipe surface
- Position the sensor at the required liquid-level detection point
- Suitable for pipe outer diameters from 5mm to 10mm
- The maximum pipe diameter should not exceed approximately 11mm
- Do not open the spring clip beyond approximately 60°
After Installation
Sensitivity Adjustment
- Use a small screwdriver to adjust the sensitivity control

Signal Output Wiring Diagram
Wire Connection
- Brown Wire – VCC: Connect to positive DC 5V to 24V power supply
- Blue Wire – GND: Connect to power supply negative / 0V
- Yellow Wire – OUT: High / Low level signal output
- Black Wire – MODE: Used to select normal or reverse output logic
Output Logic Selection
- Black MODE wire left disconnected: Positive output mode
- In positive output mode, when liquid is detected, the output changes to a high level
- When no liquid is detected in positive output mode, the output is low level
- Black MODE wire connected to GND / 0V: Reverse output mode
- In reverse output mode, when liquid is detected, the output changes to a low level
- When no liquid is detected in reverse output mode, the output is high level
Connection to Controller / MCU
The yellow OUT wire provides the high/low-level signal that can be connected to a compatible controller, microcontroller, PLC input or other control circuit.The Brown VCC wire connects to the positive supply, the Blue GND wire connects to 0V, and the Black MODE wire is used to select the required output logic.
Relay Connection
The high/low-level output can be used to drive a suitable small electric relay, provided that the relay coil current does not exceed the sensor's maximum output-current specification of 100mA.Always verify the relay operating voltage and current requirements before connecting it directly to the sensor output.
