Description:
The XKC-Y25-NPN Contactless Liquid Level Sensor is designed to detect water and other liquids without physical contact. Ideal for non-metallic containers like plastic, glass, and ceramics, this sensor can detect liquids through up to 13mm wall thickness, making it perfect for corrosive, boiling, or hygienic applications.
Equipped with intelligent liquid level memory, adjustable sensitivity, and RS485 communication, this sensor delivers accurate and stable performance even in boiling conditions or harsh industrial environments.
It features a pure electronic circuit (no mechanical parts), providing long-term reliability, low maintenance, and exceptional anti-interference capability.
