Capacitive proximity sensors

Capacitive sensors, often used for proximity measurement, represent a key technology in various industries. These devices use electric fields to detect the presence of objects, whether metallic or non-metallic.

kheeos, your specialist in industrial spare parts, offers you its range of capacitive sensors and also discover our entire range of sensors & transducers.

How do capacitive sensors work?

A capacitive sensor is essentially based on the capacitor principle. A capacitor consists of two conductive plates separated by an insulator or dielectric. When an object approaches the electric field created between these plates, it changes the capacitance of the capacitor, allowing the sensor to detect this proximity.

Electric field and detection

Detection via a capacitive sensor relies on variations in the electric field between the capacitor plates. When an object enters this field, it alters the distribution of the electric field, thereby changing the measured capacitance. This variation is then converted into an output signal by the sensor's integrated electronics. This process allows you to accurately measure the distance or presence of an object.

Measurement and precision

Capacitive sensors are distinguished by their high precision and sensitivity. They can detect very small and light objects thanks to their ability to perceive even tiny changes in the electric field. This makes these sensors particularly useful in demanding environments where precision is essential, such as in electronics manufacturing.

What are the applications of capacitive sensors?

Capacitive sensors find varied applications in several fields thanks to their ability to detect various materials, including plastics and polymers. Their versatility makes them a popular choice in modern industry.

Manufacturing industry

In the manufacturing industry, capacitive sensors are used for process control, object counting and fill level detection. For example, they play a crucial role in inventory management by checking the presence or absence of components on an assembly line. They also help improve the quality and efficiency of production.

Automotive and aeronautics

In the automotive sector, capacitive sensors are used to detect the condition of doors, seats and other components. In aeronautics, they perform similar functions by monitoring different parts of aircraft. Their reliability and robustness against severe conditions make them essential in these critical environments.

Consumer electronics

Electronic devices such as smartphones, tablets and touchscreens also incorporate capacitive sensors for precise and responsive user interaction. This type of sensor enables multi-point touch sensing, thereby improving the user experience.

Medicine and biotechnology

In the medical field, capacitive sensors are used for tasks such as monitoring bodily fluids, while in biotechnology they enable the detection of specific chemical substances. Their use in these sensitive areas improves the reliability and safety of equipment, while facilitating precise research.

kheeos Market conducts a rigorous process to select the best capacitive sensors available on the market. Each capacitive sensor offered by kheeos Market is carefully analyzed in terms of technical specifications.

Aspects such as detection range, sensitivity, resistance to environmental conditions and hardware compatibility are considered. This analysis ensures that the sensors offered meet the most stringent requirements. kheeos market therefore guarantees you quality products available on its market place!
