Capacitive Cylindrical sensors C18 Series

Datasensing C18 Series

The C18 Series delivers reliable and compact capacitive detection for a broad range of industrial applications. Unlike standard proximity sensors with fixed parameters, the C18 allows sensitivity adjustment, enabling fine-tuning for detecting challenging objects.

Design & Functionality

• Compact M18 cylindrical housing ensures compatibility with standard mounting systems and minimal installation space.
• Adjustable sensitivity allows detection of different materials (metals, plastics, liquids, powders) with one sensor model.
• Shielded or unshielded variants provide flexibility depending on mounting environment and background materials.
• High noise immunity ensures stable detection even in environments with electrical interference.

Total Crossed Beams

(Note: The term “crossed beams” is more relevant to area sensors; for the C18 capacitive sensor the key point is the fine detection field enabled by the design.)

• The sensor maintains a stable detection field across the active surface, enabling reliable sensing of small changes in material presence or level.
• Sensitive detection of thin, transparent or semi-conductive objects is achievable through precise adjustment.

Beam Pitch Options

(Again, for a cylindrical capacitive sensor, this translates to selectable sensing distances and resolutions rather than beams.)

• Selectable nominal sensing distance 3 … 12 mm depending on model variant. 
• Adjustment enables fine calibration for specific object thickness or material type.

Intrinsic Synchronism

• The C18 series uses built-in electronics for stable synchronism and detection, reducing wiring complexity and installation time.
• Single-unit mounting with built-in detection field ensures consistent performance across the sensor’s rated sensing distance.

Operational Advantages

• High Switching Frequency: Capable of switching up to 50 Hz, enabling use in moderately fast automation tasks. 
• Easy Configuration (Teach-In): The adjustable sensitivity and model variants allow quick set-up and tuning for specific materials or backgrounds.
• Applications: Ideal for detecting metals, plastics, ceramics, liquids and powders in automotive, electronics, packaging and general manufacturing environments.
  The C18 series is especially suitable where space is limited, yet high reliability and flexibility are required.
