Description

The XKC-Y26L-NPN utilizes a capacitive sensing principle to detect liquid levels without physical contact, making it ideal for sterile or corrosive fluid applications. It senses changes in dielectric constant through the wall of non-metallic containers, providing a reliable digital switching signal.

With its 3.3V logic compatibility and NPN output, it interfaces directly with common microcontrollers and digital input modules. The IP67-rated enclosure ensures reliable performance in damp or dusty environments, suitable for a wide range of industrial and DIY projects.

Key Features

  • Non-contact capacitive liquid level detection.
  • 3.3V DC power supply compatible with 5V logic systems via level shifting.
  • NPN open-collector output (low pulse effective) for easy digital interfacing.
  • IP67 protection rating for dustproof and waterproof operation.
  • User-adjustable sensitivity potentiometer for fine-tuning detection.
  • Designed for use with non-metallic containers (plastic, glass).
  • Compact and durable construction for long-term reliability.
  • High-value build optimized for automation and monitoring systems.

Applications

  • Water tank level monitoring in home automation and aquaponics systems.
  • Liquid level detection in chemical dispensing equipment with corrosive fluids.
  • Beverage and liquid packaging machine level control.
  • Reservoir monitoring for humidifiers, coffee machines, and medical devices.
  • Leak detection and flood prevention systems in enclosures.

Frequently Asked Questions

What is the operating voltage range for the XKC-Y26L sensor?

The sensor is designed for a nominal 3.3V DC supply. While it may tolerate a small range around this voltage (e.g., 3.0V to 3.6V), it is not rated for 5V operation. For 5V systems, a logic level converter or appropriate voltage divider on the output signal is required to prevent damage.

How do I interface the NPN output with my Arduino or Raspberry Pi?

The NPN output is an open-collector type. Connect the sensor's output pin to your microcontroller's digital input pin via a pull-up resistor (typically 4.7kΩ to 10kΩ) to the MCU's logic voltage (3.3V or 5V). When liquid is detected, the output pulls low, creating a readable logic low signal on your input pin.

Can this sensor detect liquid through any type of container?

No, it is specifically designed for non-metallic containers such as plastic, glass, or ceramic. Metal containers shield the capacitive field, preventing detection. The container wall thickness also affects sensitivity, which can be adjusted using the onboard potentiometer.

What does the IP67 rating mean for installation?

IP67 rating indicates the sensor is completely dust-tight (6) and can withstand immersion in water up to 1 meter for 30 minutes (7). This allows for installation in damp, dusty, or outdoor environments, but the electrical connections should still be properly sealed for long-term reliability.
