Why Choose the Carlo Gavazzi CB32CLN20TOFT Capacitive Proximity Sensor?

The Carlo Gavazzi CB32CLN20TOFT is a robust capacitive proximity and level sensor designed for reliable detection of solid, liquid and granulated materials in industrial automation applications. As part of the Carlo Gavazzi CB32CLN Series, it combines adjustable capacitive sensing, a two-wire AC output and integrated time-delay functionality in a durable 32 mm cylindrical housing.

This sensor uses capacitive detection technology to identify materials without requiring mechanical contact, making it particularly suitable for monitoring product levels in tanks, silos, hoppers and containers. Its adjustable sensitivity enables the sensing distance to be configured for different target materials, while Carlo Gavazzi TRIPLESHIELD™ protection provides high noise immunity for dependable operation in demanding industrial environments.

With a 20–250 V AC power supply, adjustable 2–20 mm sensing distance, normally open SCR output and fixed 30 s ON delay, the CB32CLN20TOFT provides flexible integration into industrial control systems. The sensor features a non-flush design, IP67 protection and a factory-fitted 2 m PVC cable.

Reliable Capacitive Detection for Industrial Processes

Capacitive proximity sensors detect changes in capacitance produced when a target material enters the sensor's detection field. This enables the Carlo Gavazzi CB32CLN20TOFT to detect a wide variety of materials, including grain, powders, granulates, solids and liquids, making it particularly useful for industrial level indication and material-presence applications.

The CB32CLN20TOFT is especially suited to applications where a delayed response is required. Its integrated 30 s ON-delay means the output is activated only after the detection condition has remained present for the specified period, helping prevent unwanted switching caused by brief or intermittent material detection. The adjustable sensing range and TRIPLESHIELD™ protection further support reliable operation in industrial automation systems.

Typical Applications

• Grain and granular material level detection.
• Silo, hopper, tank and container monitoring.
• Powder and solid material detection.
• Liquid level monitoring in suitable installations.
• Agricultural processing and storage equipment.
• Food and beverage processing machinery.
• Conveyor and material handling systems.
• Plastic and rubber processing machinery.
• Industrial process automation and level control.
