Proximity Sensors – the 9863-3333 application field and working principle

Proximity sensors are one of the most important types of sensors used in industry and automation. They are widely used in a variety of applications such as level sensing, distance measurement, object detection, vibration and movement sensing, and more. The 9863-3333 is an inductive proximity sensor that is capable of detecting the presence or absence of ferrous metal within a few millimeters of its sensing surface.

The 9863-3333 inductive proximity sensor range is designed for use in areas where reliability and long life are paramount. The sensors are constructed from a Zinc alloy body and have a rugged stainless steel sensing face. The internal electronics are also housed in a robust, shock-resistant casing. This ensures that the 9863-3333 performs reliably in the most demanding industrial applications.

The 9863-3333 is an ‘on/off’ type of proximity sensor, meaning that it is capable of switching to either a low or high state depending on the presence or absence of a ferrous metal object. When a ferrous object is detected by the sensor, it switches to a high state and sends out a signal. This signal can then be used to activate other systems or processes.

The working principle of the 9863-3333 inductive proximity sensor is based on the principle of Faraday’s law of induction. This states that whenever a conductor is moved through a magnetic field, an electric current is induced in the conductor. This current is known as an eddy current. The 9863-3333 sensor works by using an internal coil of wire that creates an oscillating magnetic field. When a ferrous object is placed within the range of the magnetic field, eddy currents are induced in the object. These eddy currents create an opposing magnetic field that is detected by a Hall effect device in the sensor. This triggers the output switch to change state.

The 9863-3333 inductive proximity sensor is an ideal choice for applications where reliable operation in harsh environmental conditions is required. The sensor is rated IP56 and is also resistant to corrosion, humidity and shock. It is capable of operating in temperatures ranging from -25°C to +85°C, making it suitable for use in a wide variety of industrial environments. The sensor also has an impressive response time of just 1 millisecond.

The 9863-3333 inductive proximity sensor is also cost effective and easy to install. It is available in a range of different sizes to suit different application requirements and can be mounted in a number of different ways, from flush mounting to a surface or panel mounting. Sensor wiring is simple and only requires two wires for power and a single wire for the signal output.

In summary, the 9863-3333 inductive proximity sensor is a versatile, reliable and cost-effective solution for a variety of industrial applications where reliable operation in harsh environments is required. The sensor can detect the presence or absence of ferrous metal objects within a few millimeters of its sensing surface, and is rated IP56 and capable of operating in temperatures ranging from -25°C to +85°C. The sensor is also easy to install and requires only two wires for power and one wire for the signal output.
