Why Choose the Carlo Gavazzi VC12RN230 Capacitive Sensor?

The Carlo Gavazzi VC12RN230 is a robust capacitive proximity and level sensor with an integrated SPDT relay output, designed for reliable detection of solid, liquid and granular materials in industrial automation and level-control applications. As part of the Carlo Gavazzi VC12RN series, it combines adjustable capacitive sensing with a relay output capable of directly interfacing with a wide range of control circuits.

The VC12RN230 provides an adjustable sensing distance of 4–12 mm and uses a non-flush, cylindrical sensing arrangement. Capacitive technology allows the sensor to detect both conductive and non-conductive materials, making it particularly useful for monitoring liquids, powders, pellets and other bulk materials through suitable non-metallic container walls.

Designed for a nominal 230 V AC supply, with a rated supply range of 195–265 V AC, the VC12RN230 features an SPDT change-over relay rated up to 2 A / 240 V AC, a durable thermoplastic polyester housing, 2 m PVC cable and IP67 protection for dependable industrial operation.

Key Advantages

• Adjustable 4–12 mm sensing distance allows sensitivity to be matched to the application.
• SPDT change-over relay output provides flexible control and switching functionality.

Reliable Capacitive Detection for Solids and Liquids

Capacitive sensors detect changes in the electrical capacitance around the sensing face when a target material enters the detection field. Unlike inductive sensors, which are primarily intended for metals, capacitive sensors can detect a broad range of conductive and non-conductive materials, including liquids, powders, granules, plastics and other bulk products.

The VC12RN230 is particularly suited to industrial level-control applications because its sensitivity can be adjusted between 4 and 12 mm. Its integrated SPDT relay provides a convenient change-over contact for connection to control equipment or suitable loads, reducing the need for a separate switching amplifier in many applications.

Typical Applications

• Liquid level detection in tanks and containers.
• Powder and granular material level monitoring.
• Hopper, silo and bin level control.
• Agricultural feed and grain handling systems.
• Packaging and processing machinery.
• Detection through suitable non-metallic container walls.
• Industrial automation and material handling equipment.
