This model operates from a DC 24V power supply and provides an NPN output interface. The sensor provides reliable liquid-level detection while remaining completely outside the container, helping reduce contamination, corrosion, and leakage risks.
The internal control circuit detects this capacitance change and converts it into an electrical output signal. When the detected change reaches the set threshold, the sensor determines that liquid is present and switches the NPN output.
The gap between the sensor sensing surface and the container wall should be less than 0.5mm. For optimum liquid detection accuracy and sensitivity, no gap is recommended between the sensing surface and container wall.

Description
XKC-Y26S 24V DC Non-Contact Liquid Level Sensor with NPN Output
The XKC-Y26S-NPN-DC 24V is a non-contact capacitive liquid level sensor designed for accurate liquid detection through the outer wall of non-metallic containers and pipes. It detects the presence of liquid without direct contact with the medium, making it suitable for sealed containers, water tanks, pipelines, automatic filling systems, industrial equipment, and automation applications.This model operates from a DC 24V power supply and provides an NPN output interface. The sensor provides reliable liquid-level detection while remaining completely outside the container, helping reduce contamination, corrosion, and leakage risks.

Working Principle
The sensor works using the capacitive sensing principle. When no liquid is present near the sensing surface, the sensor maintains its normal capacitance level. When liquid reaches the sensing position, the electrical capacitance detected through the non-metallic container wall changes.The internal control circuit detects this capacitance change and converts it into an electrical output signal. When the detected change reaches the set threshold, the sensor determines that liquid is present and switches the NPN output.

Mechanical Drawing & Dimensions
Gap Requirement Between Sensor and Container Wall
The sensing surface should be attached tightly to the outer wall of the container. Use AB glue or another durable and strong adhesive to secure the sensor firmly to the container surface.The gap between the sensor sensing surface and the container wall should be less than 0.5mm. For optimum liquid detection accuracy and sensitivity, no gap is recommended between the sensing surface and container wall.
