Capacitive Cylindrical sensors CT Series

Datasensing CT Series

The CT Series offers a robust and flexible capacitive proximity sensing solution for industrial environments. With features such as sensitivity adjustment, metal housing, and full protection against electrical damage, the CT sensors enable dependable object detection across varied materials and mounting conditions.

Design & Functionality

• Housed in a metal M30 cylindrical body, the CT Series is built for durability and standard mounting compatibility.
• Sensitivity can be adjusted via trimmer, allowing fine-tuning for detection of different materials or backgrounds.
• Available in shielded or unshielded variants, with nominal sensing distances from approximately 2 to 20 mm, depending on model configuration. sensorcentre.com
• Designed with robust electronic protection: reverse-polarity, short-circuit protection (auto reset), and impulsive over-voltage protection — ensuring high reliability in industrial harsh conditions. datasensing.com+1

Total Crossed Beams

(In the case of the CT Series, the equivalent concept is the stable capacitive detection field across the active area.)

• The detection field remains consistent across the rated sensing distance, supporting reliable sensing of objects even when mounted with variations in background or material.
• Helps reduce false triggers or missed detections when targets are transparent, irregular or positioned unpredictably.

Beam Pitch Options

(Here this translates to selectable sensing distances and detection resolution rather than physical beam spacing.)

• The sensors provide nominal sensing distances in the range of ~2 to 20 mm, model-dependent. sensorcentre.com+1
• With repeat accuracy typically ≤ 10 % and thermal drift < 20 %, the CT Series delivers consistent detection performance over time and temperature changes. datasensing.com

Intrinsic Synchronism

• Built-in electronics handle synchronism and protection functions, reducing external wiring complexity.
• Typical time-before-availability is ≤ 100 ms, allowing the sensor to become operational quickly after power-up. datasensing.com

Operational Advantages

• High Switching Frequency: Capable of switching at ~100 Hz, enabling use in moderately fast automation processes. datasensing.com
• Easy Configuration (Teach-In/Trimmer adjustment): The adjustable sensitivity function means setup is faster and can be adapted to specific material types or mounting environments.
• Applications: Ideal for detecting a wide variety of materials (metals, plastics, ceramics, liquids, powders) in automotive, electronics, packaging and general manufacturing systems. The CT Series is especially suitable where compact form, material versatility and industrial ruggedness are required.
