Magnetic sensors, particularly position, proximity, and speed (modules) represent an important class of industrial and consumer electronics. In this article, we\'ll look at the MK18-B-100W magnetic sensor, its application field and working principle. This sensor operates on the principle of eddy-current and is capable of measuring the magnetic field both in presence and absence of a magnetic field.

Application Field

The MK18-B-100W magnetic sensor is ideal for a variety of implementations, from industrial automation systems to consumer electronics. This highly versatile magnetic sensor finds applications in a number of diverse fields. The sensor can be used for profile measurement of thin ferromagnetic plates or substrates, and it is particularly useful in non-contact sensing of position and speed in the consumer and automotive industries. Its small, lightweight design makes it a great choice for applications where space and power consumption are important factors.

The MK18-B-100W is also suitable for use in medical diagnostics since it is able to detect low frequency magnetic fields, useful in various MRI (magnetic resonance imaging) readings. This includes sensing the presence of tissue, measuring the strength of a magnetic field, and identifying a variety of materials. In robotics, the MK18-B-100W magnetic sensor is useful for providing feedback on the robot\'s position and movements.

Working Principle

The MK18-B-100W magnetic sensor operates on the eddy-current principle. It works by using the generated emf to measure the presence or absence of a magnetic field. The device contains a permanent magnet connected to a core of material that produces an emf when subjected to a magnetic field. This emf is then further generated into a high-frequency oscillating signal. The amplitude of this oscillation depends on the strength of the magnetic field.

The MK18-B-100W is typically operated with a fixed DC bias voltage, which focuses the sensor around zero-magnetic field for a more reliable operation. This sensor can work with different frequency ranges from a few kHz up to several hundred kHz. Furthermore, the MK18-B-100W exhibits a digital output signal, making it an ideal candidate for remote sensing and long-distance readout. Since it is a digital output sensor, the MK18-B-100W is also very accurate and reliable.

Advantages

The MK18-B-100W magnetic sensor offers several advantages over traditional magnetic sensors. It provides an ultra-reliable, low-power performance, and its digital output permits remote sensing and long-distance readout. It is also much thinner than traditional sensors, which makes it suitable for tight spaces. Its highly versatile operating range also enables measurement in virtually any environment, from extreme temperatures to high-ambient noise.

The MK18-B-100W is also capable of comparing the magnetic field from two emf sources, allowing for precise and reliable measurement of small differences in magnetic fields. This makes it possible to detect objects and materials that are exposed to magnetic fields. In addition, the sensor\'s small size allows for easier and more accurate integration into both consumer and industrial electronic devices.

Conclusion

The MK18-B-100W is a highly versatile and reliable magnetic sensor that can be used in a variety of applications. Its digital output, precision, and versatility make it a superior choice for non-contact sensing of low-frequency magnetic fields. Furthermore, its small size and easy integration to both consumer and industrial electronics make it the best choice for a wide range of applications.
