Why Choose the Carlo Gavazzi CD34CNFLFPOT5 Capacitive Level Sensor?
The Carlo Gavazzi CD34CNFLFPOT5 is a specialised capacitive level sensor with foreground suppression designed for reliable detection of liquids and other materials through non-metallic container walls. Part of the Carlo Gavazzi CD34 capacitive sensor series, it combines a compact plastic housing with PNP normally open switching and an integral pigtail connection for straightforward integration into industrial equipment.
Foreground suppression technology allows the CD34CNFLFPOT5 to distinguish the required material from the container wall immediately in front of the sensing face. This makes it particularly useful for external level detection through plastic or glass vessels, where conventional capacitive sensors may otherwise respond to the container itself.
The sensor is designed for 10–30 V DC operation and provides a PNP normally open (NO) transistor output. Its compact rectangular plastic construction enables space-efficient mounting alongside tanks, pipes and containers, while the pigtail electrical connection supports convenient integration with industrial wiring and automation systems.

Reliable Foreground-Suppressed Level Detection
Conventional capacitive sensors respond to changes in dielectric properties within their sensing field, which allows them to detect many liquids and non-metallic materials. When a sensor is mounted externally on a container, however, the wall itself can influence the sensing field. Foreground suppression is designed to minimise this effect so that the sensor can focus on detecting the material behind the container wall.
This operating principle makes the Carlo Gavazzi CD34CNFLFPOT5 particularly useful where direct contact with the process medium is undesirable. External mounting can simplify installation and maintenance while avoiding sensor exposure to the liquid or material inside the vessel.
Typical Applications
- Liquid level detection through plastic containers.
- External monitoring of tanks and vessels.
- Level detection through suitable glass walls.
- Filling and dispensing machinery.
- Packaging and processing equipment.
- Industrial fluid handling systems.
- Machine automation and process monitoring.

Frequently Asked Questions
What is the Carlo Gavazzi CD34CNFLFPOT5 used for?
The CD34CNFLFPOT5 is a capacitive level sensor designed for non-contact detection of liquids and suitable materials, particularly through non-metallic container walls.
What does foreground suppression mean on the CD34CNFLFPOT5?
Foreground suppression helps the sensor suppress the influence of the container wall immediately in front of it so that it can detect the material behind the wall more reliably.
What output does the CD34CNFLFPOT5 provide?
The sensor provides a PNP transistor output with a normally open (NO) switching function for connection to compatible industrial control equipment.
What supply voltage does the CD34CNFLFPOT5 use?
The CD34CNFLFPOT5 is designed for a 10–30 V DC supply, making it suitable for common industrial automation systems.
Does the CD34CNFLFPOT5 need to contact the liquid?
No. Its capacitive foreground-suppression principle enables non-contact level detection through suitable non-metallic container walls, allowing the sensor to be mounted externally in appropriate applications.
