Proximity sensors are increasingly used in many industrial applications for detecting the presence of objects or materials without any physical contact. The GX-M18B-U is a professionally engineered Proximity Sensor developed by General Electric that is designed to detect metals and can also be used to detect a wide range of non-metallic materials, including certain types of plastic.

The GX-M18B-U Proximity Sensor is mostly used to detect the presence of metal or non-metallic objects that come into contact with it. This type of device is precise and can detect the presence of objects from a distance of 0-18mm and can be activated from various angles without any additional work required. It is also available in multiple configurations for many types of applications.

The main component of the GX-M18B-U Proximity Sensor is the external coil tube shaped housing that is made of plastic and usually accompanies two integrated circuit boards. The two boards contain different components labelled as the Drive, and the Processor. The Processor board houses the mechanical parts for the Proximity Sensor while the Drive Board is used to amplify the signal detected by the Proximity Sensor.

When the Proximity Sensor is activated, the Drive Board emits a high frequency alternating current, a signal at the same frequency as the coil. This signal then travels through the object or material. As the signal passes through a metal object, it creates a distortion in the alternating current. This distortion can be detected by the Sensor’s coil and is registered as an electric signal that triggers the Processor Board.

The Processor Board then evaluates this signal and decides whether or not to activate the Proximity Sensor. Depending on the distance between the sensed object and the Sensor, the high frequency alternating current generated by the drive board can be further amplified by the Processor Board to be registered as an object or a material at a greater distance. This amplified signal can also be used to determine the orientation of the sensed object.

When it comes to application field, the GX-M18B-U Proximity Sensor is mainly used in industrial automation and robotics, in various systems such as for the positioning and as momentary active switches. Furthermore, they can be used in manufacturing plants, production lines, and other machines used to process a wide range of materials and products. Moreover, it can be used as an interface for industrial computers and as a safety device.

In summary, the GX-M18B-U Proximity Sensor is a widely used and reliable device developed by General Electric with an impressive range of applications. Its working principle of transmitting a frequency signal and detecting any distortion in the signal is a sure way to detect the presence of a wide range of objects and materials without having any physical contact.
