Capacitive Cylindrical sensors C12 Series

Datasensing C12 Series

The C12 Series offers a flexible and space-saving solution for capacitive detection in industrial automation. With a fine sensing range and adjustable threshold, the C12 ensures precise detection of materials regardless of their composition or mounting environment.

Design & Functionality

• The sensor is housed in a compact M12 × 1 cylindrical body, making it ideal for tight installations.
• It supports adjustable sensitivity (Teach-In) so you can calibrate the sensor to detect specific objects while ignoring background or mounting surfaces.
• Available in shielded or unshielded versions, providing material-agnostic detection—metals, plastics, liquids or powders can all be detected reliably.
• It offers high immunity to electrical noise and rugged industrial performance, making it suitable for harsh manufacturing or packaging environments.

Total Crossed Beams

(Note: While “crossed beams” is more relevant to area sensors, within the context of the C12 Series the important concept is the stable detection field achieved by the housing & electronics design.)

• Maintains a consistent detection zone across the rated sensing distance, enabling reliable detection of small or thin items.
• Helps reduce false triggers or missed detections in challenging background conditions.

Beam Pitch Options

(For this style of sensor, equivalent attributes are sensing distance options and resolution.)

• Nominal sensing distances range from approximately 0.5 … 4 mm (shielded), and up to 0.5 … 8 mm (unshielded), depending on model.
• The selectable range lets you tailor the sensor for ultra-short-range precision detection or slightly greater reach for larger targets.
• Repeat accuracy is excellent (around ±5%) and thermal drift is under 20%, ensuring consistent long-term detection performance.

Intrinsic Synchronism

• The C12 incorporates built-in electronic synchronism and noise-immunity design, removing the need for external setup or multiple sensor alignment.
• With automatic NPN/PNP output detection, NO/NC configuration and quick Teach-In capability, the sensor supports fast installation and reliable operation.

Operational Advantages

• High Switching Reliability: Although switching frequency is modest (≤15 Hz), the C12 excels in stable detection scenarios where precision and repeatability matter.
• Easy Configuration (Teach-In): Press-and-hold Teach-In button enables calibration of the background and target, allowing the sensor to be optimized for your specific application.
• Applications: Ideal for presence detection, level detection, or material verification in applications such as injection molding, packaging, liquid/powder hoppers and small-part assembly. Its compact M12 form-factor and adjustable sensitivity make it especially suited for tight spaces or where detection of mixed materials is required.
