Description

The Pro-Range XKC-Y27C-NPN utilizes a capacitive sensing principle to detect the presence of liquid without direct contact. This method senses changes in dielectric constant through the container wall, making it ideal for applications where contamination, corrosion, or sensor maintenance must be avoided. The sensor’s sensitivity can be adjusted to accommodate different wall materials and thicknesses.

Housed in a robust, IP67-rated enclosure, the sensor is protected against dust and temporary immersion, ensuring reliable performance in industrial and laboratory settings. Its wide operating temperature range from -25°C to +85°C allows for deployment in environments with significant thermal variation, from cold storage to heated process lines.

Key Features

  • Non-Contact Capacitive Detection: Prevents contamination and sensor wear by sensing liquid through container walls.
  • Adjustable Sensitivity: Fine-tune detection threshold for optimal performance with various container materials and wall thicknesses.
  • Robust IP67 Enclosure: Waterproof and dust-tight construction for demanding industrial and outdoor applications.
  • Wide Temperature Tolerance: Stable operation across an extensive range from -25°C to +85°C.
  • Fast Switching Response: Sub-500ms response time enables real-time control and monitoring.
  • Universal Voltage Compatibility: 5-24V DC input simplifies integration with both low-voltage logic and standard industrial power rails.

Applications

  • Non-invasive liquid level monitoring in chemical, pharmaceutical, and food-grade tanks.
  • Leak detection and sump pump control in basements, HVAC systems, and machinery.
  • Water level sensing in appliances like coffee makers, humidifiers, and water dispensers.
  • Process control in industrial automation for coolant, lubricant, or solvent reservoirs.
  • Liquid presence verification in transparent or opaque piping and vessels.

Frequently Asked Questions

What is the maximum container wall thickness this sensor can detect through?

The Pro-Range XKC-Y27C-NPN is designed to detect liquid presence through non-metallic container walls up to 4mm thick. The effective range can be influenced by the wall material's dielectric constant; sensitivity adjustment may be required for optimal performance with different plastics or glass.

How do I wire the NPN output to a microcontroller like an Arduino?

The NPN output is an open-collector switch. Connect the sensor's V+ to a 5-24V DC supply, GND to common ground, and the output wire to your microcontroller's digital input pin through a pull-up resistor (typically 10kΩ to Vcc). The output will pull to GND (logic LOW) when liquid is detected.

Can this sensor be used with conductive or metallic containers?

No. The capacitive sensing principle requires a non-conductive, dielectric barrier between the sensor face and the liquid. Metallic or highly conductive containers will shield the electric field, preventing reliable detection. It is intended for use with plastic, glass, or ceramic vessels.

What is the sensor's response time, and is it adjustable?

The sensor has a fast response time of less than 500 milliseconds from detection to output state change. The response speed is fixed by the internal circuitry, but the detection sensitivity (the threshold for triggering) can be adjusted via the potentiometer on the sensor body to account for different wall materials.
