Proximity Sensors are automated devices which enable the detection of objects without actual physical contact. The 9906-4700 is a capacitive proximity sensor developed for non-contact sensing of conductive and non-conductive objects, making it suitable for a wide range of applications. This article will explain the application field and working principle of the 9906-4700.

Application Field of the 9906-4700

The 9906-4700 is primarily used in industrial automation, robotic automation, plastic and metal processing and paint and lacquer applications. It can also be used in non-destructive testing, material sorting and detection of objects in challenging environments. The 9906-4700 is specially designed for difficult applications with high vibration, dust and humid environments. It is resistant to interference from high frequency sources such as welding arcs and x-rays, making it ideal for high-precision applications.

Working Principle of the 9906-4700

The 9906-4700 is a capacitive proximity sensor which uses an oscillant capacitor to detect objects. This type of sensor operates by generating a variable electric field. When an object enters the electric field, it will alter the system’s capacitance, and can then be detected. This type of sensor is non-contact, meaning it does not need to come into physical contact with the object it is detecting. The sensor is able to detect objects regardless of size, shape or material, as long as they are electrically conductive or non-conductive.

The 9906-4700 features a wide sensing range and high sensitivity. The sensing range can be adjusted from very close to up to 8mm, and the sensing frequency is adjustable from 1 kHz to 30 kHz. This allows it to detect objects regardless of their size. Additionally, it is designed to be able to detect objects over a wide range of temperatures, from -25℃ to 70℃. These features make the 9906-4700 a highly versatile and reliable proximity sensor.

Conclusion

The 9906-4700 is a capacitive proximity sensor developed for non-contact sensing of a wide range of objects. It is suitable for use in industrial automation, robotic automation, non-destructive testing and other challenging environments. It is particularly resilient to high electric interference and temperature fluctuations. This makes it a reliable and versatile proximity sensor for applications where accuracy and precision are important.
