Proximity sensors (also known as inductive proximity sensors) are electronic devices that are used to detect and measure the presence of objects without physical contact. The GX-MK18A-P is a type of inductive proximity sensor that is used in many industries, including automotive, medical, and military applications. This article will discuss the GX-MK18A-P\'s application field and working principle.

Application Field

The GX-MK18A-P is a robust and reliable inductive sensor that is specifically designed for high-precision, fast response requirements. It is able to detect and measure the presence of metal objects up to 10 mm away. This makes it ideal for use in environment with tight space constraints, such as in robotic systems. It is also commonly used in automated production lines to detect the presence of various components, such as switches and other parts.

The GX-MK18A-P can also be used in non-industrial applications, such as entertainment lighting and home security systems. For instance, if a person walks near a motion-activated light switch, the GX-MK18A-P will detect the person’s presence and turn the light on. Similarly, the GX-MK18A-P can be used in home security systems to detect the presence of intruders.

Working Principle

The GX-MK18A-P is an electro-magnetic type proximity sensor, meaning it relies on electromagnetic induction to detect nearby objects. This electromagnetic induction is achieved by creating a magnetic field between the sensor and the object. When a conductive metal object enters this magnetic field, eddy currents are created, which in turn create an opposing magnetic field that is detected by the GX-MK18A-P.

The GX-MK18A-P also uses an oscillator circuit to detect the object’s presence. This oscillator circuit consists of a coil, a capacitor, and a transistor. When a metal object enters the magnetic field, it reduces the capacitance of the oscillator circuit, which can then be used to detect the presence of the object. The GX-MK18A-P’s output signal is then sent to an interpretation circuit which ensures a stable and reliable reading.

Conclusion

The GX-MK18A-P is a versatile and reliable proximity sensor that is often used in automated production lines and entertainment lighting systems. It is a type of inductive proximity sensor that relies on electromagnetic induction to detect the presence of metal objects up to 10 mm away. The GX-MK18A-P also utilizes an oscillator circuit to detect the object’s presence, which is then sent to an interpretation circuit for a stable and reliable reading.
