vc12rt12010m – capacitive sensor,relay,timer

Why Choose the Carlo Gavazzi VC12RT12010M Capacitive Sensor?

The Carlo Gavazzi VC12RT12010M is a robust capacitive proximity and level sensor with integrated SPDT relay and adjustable OFF-delay timer, designed for reliable detection of solid, liquid and granular materials. Its non-flush cylindrical design provides an adjustable sensing distance of 4–12 mm, allowing sensitivity to be matched to different target materials and installation conditions.

Unlike conventional transistor-output proximity sensors, the VC12RT12010M incorporates an SPDT change-over relay rated at 2 A / 240 V AC, allowing suitable loads to be controlled directly. The integrated adjustable OFF-delay timer keeps the relay output active for a selected period after the sensing condition ends, providing useful timing functionality for level control, material handling and industrial process applications.

Designed for a nominal 120 V AC supply, with a rated operating range of 102–132 V AC, the VC12RT12010M combines capacitive sensing, relay switching and timing in one self-contained device. Its thermoplastic polyester housing, 2 m PVC cable and IP67 protection provide dependable operation in industrial and agricultural environments.

Capacitive Level Detection with Adjustable OFF-Delay

Capacitive sensors detect changes in electrical capacitance caused by the presence of a target material. This allows the Carlo Gavazzi VC12RT12010M to detect solids, fluids and granular substances without mechanical contact. Its adjustable 4–12 mm sensing distance allows sensitivity to be configured for different materials and installation conditions, making it particularly useful for level and material-presence applications.

The integrated OFF-delay timer adds valuable control functionality by keeping the relay energised for an adjustable period after the detected target is removed or the sensing condition ends. With a delay range of 1 s–10 min and an integrated SPDT relay, the VC12RT12010M can simplify control circuits and help prevent brief changes in material level from causing immediate output switching.

Typical Applications

• Grain and animal-feed level detection.
• Liquid and fluid level sensing.
• Powder and granular material detection.
• Hopper and silo level control.
• Agricultural machinery and storage systems.
• Tank and vessel level detection.
• Material presence monitoring.
• Industrial process control requiring delayed switch-off.
