Proximity sensors are electronic devices used to detect the presence of an object without any physical contact. They are commonly used in industrial automation applications, but are also found in consumer electronic devices such as remote controls, kitchen appliances, cell phones, and toys. The 9966-4170 is a type of proximity sensor that uses capacitive technology to detect the presence of an object or materials.

Application Field

The 9966-4170 is a versatile and reliable capacitive proximity sensor, providing reliable detection of objects, materials, and liquids over a wide temperature range. Its applications include detecting the presence of objects in a wide range of environments, including harsh and dusty environments, as well as wet and submerged environments. Some of the most common applications for this sensor include: level detection of fluids and other materials, levels of ferrous metals for industrial machinery, sensing of transmission belts and conveyor belts for manufacturing, and monitoring door openings for security systems.

Working Principle

The 9966-4170 proximity sensor works on the principle of capacitive sensing. It consists of two capacitor plates, an oscillator and a driver circuit. The capacitor plates are connected to a voltage source and the oscillator is responsible for generating a constantly changing signal. When an object is placed near the sensor, it changes the characteristics of the electric field between the two plates. The driver circuit then converts the changed characteristics of the electric field into an output signal, which is used to trigger an alarm or other switch.

The capacitive sensing technology used by the 9966-4170 is very sensitive and can be used to detect objects or materials even in very low power situations. It is also very low cost and can be used in applications that require high resolution such as automotive engine control systems.

The 9966-4170 is a highly versatile and reliable capacitive proximity sensor, offering reliable detection of objects and materials over a wide temperature range. Its applications range from detecting the presence of objects in harsh and dusty environments to using it as a switch for security systems and monitoring door openings. Its capacitive sensing technology provides extremely accurate and reliable results and can be used in a variety of industrial and consumer applications.
