Proximity sensors are sensor devices commonly used in industrial automation. Their function is to detect the presence of an object within a certain range of distance without physical contact. The GX-M18B is a micro-electromechanical system (MEMS) technology-based non-contact Ultra-miniature Proximity Sensor which is used to detect the presence of metallic objects. This article will discuss the application field and working principle of the GX-M18B.

The GX-M18B is a miniaturized device with a sensing distance which is very short ranging from 0.5 to 2mm. It is designed for SPM (Smart Production Machine) application, handheld tool, and presses for detection of fine objects. This device is also suitable for robot applications such as SCARA, Cartesian, and 6-axis robots. Due to its micro size and weight of only 1.5g, it can be easily integrated into restrictions such as narrow spaces, narrow walls, or shafts of robots.

The GX-M18B utilizes the electromagnetic induction principle in its working principle. This principle is based on the magnetic field generated when an alternating current is passed through a coil. The magnetic field is used to detect the presence of a metallic object. When a metallic object comes into contact with the magnetic field, it will induce an EMF (electromagnetic field) which is then converted into a signal output by the GX-M18B. This signal is amplified and finally sent to the appropriate control system for processing.

The GX-M18B has variety of features that make it standout among other similar devices. It has an operating temperature ranging from -25°C to +85°C which makes it suitable for a variety of industrial environments. Additionally, due to its micro size it is very easy to install and is also very reliable. Furthermore, the GX-M18B uses a digital output circuit which allows for more flexibility in programming and more accuracy in sensing.

In conclusion, the GX-M18B Proximity Sensor is a versatile and reliable device which can be used in a variety of industrial automation applications. Its combination of small size and enhanced features make it an ideal choice for applications such as SPM, handheld tools, and robots. Its working principle is based on the electromagnetic induction principle which allows it to accurately detect the presence of metallic objects. Thus, the GX-M18B is a great choice for industrial automation applications.
