Why Choose the Carlo Gavazzi CB32CLN20QVAX5M Capacitive Proximity Sensor?

The Carlo Gavazzi CB32CLN20QVAX5M is a robust capacitive proximity and level sensor designed for reliable detection of solid and liquid materials in industrial applications, including hazardous areas where combustible dust may be present. As part of the Carlo Gavazzi CB Series, it combines an adjustable sensing range, relay output and integrated OFF-delay timing in a durable 32 mm cylindrical housing.

This sensor uses capacitive sensing technology to detect materials without direct mechanical contact and can be used for applications such as level monitoring, presence detection and process control. Its adjustable sensitivity allows the detection distance to be matched to the target material, while Carlo Gavazzi TRIPLESHIELD™ EMC protection helps provide stable operation in electrically demanding industrial environments.

With a 20–28 V AC/DC rated supply range, an adjustable 4–20 mm sensing distance, SPDT relay output and an adjustable 1 s–10 min OFF delay, the CB32CLN20QVAX5M is suited to a wide variety of automated material handling and level-detection duties. This version is supplied with a 5 m PVC cable and carries an ATEX Zone 20 dust rating for suitable hazardous-area applications.

Reliable Capacitive Detection for Industrial Processes

Capacitive proximity sensors detect changes in electrical capacitance caused by the presence of a target material. This allows the CB32CLN20QVAX5M to detect many conductive and non-conductive materials, including powders, granulates and liquids, making it particularly useful for industrial level monitoring and material presence applications.

The adjustable sensing distance allows the sensor to be configured for different materials and installation conditions, while its integrated OFF-delay function can hold the output state for a defined period after the target is no longer detected. This helps prevent unwanted switching and provides additional control flexibility in automated filling, conveying and process-monitoring systems.

Typical Applications

• Powder and granular material level detection.
• Industrial silo, hopper and vessel monitoring.
• Liquid level sensing through suitable non-metallic materials.
• Food and bulk-material processing equipment.
• Packaging and filling machinery.
• Conveyor and material handling systems.
• Process automation and presence detection.
• Industrial applications involving potentially explosive dust atmospheres.
