XKC-Y25 Non Contact Liquid Level Sensor NPN 5VDC

The XKC-Y25 is an innovative non-contact liquid level sensor that detects liquid presence through container walls without direct contact with the liquid itself. Using advanced capacitive sensing technology, this sensor eliminates contamination risks, corrosion issues, and maintenance hassles associated with traditional float switches. Simply mount the sensor on the outside of plastic, glass, or thin-walled containers up to 10mm thick, and it accurately detects liquid levels with high reliability.

Featuring NPN output with 5V DC operation, the XKC-Y25 is perfect for water tanks, beverage dispensers, aquariums, chemical containers, coffee machines, and automated filling systems. The sensor provides digital output signal that can be directly connected to microcontrollers, PLCs, or relay modules for automated control applications. No drilling, no leaks, and no sensor wear – ideal for food-grade, medical, and industrial applications where hygiene and reliability are paramount. Easy installation with adjustable sensitivity for different container materials.
