KMZ43T,118 Application Field and Working Principle

Introduction to Magnetic Sensors – Linear, Compass (ICs)

Magnetic sensors have become an important part of modern industrial and consumer products, ranging from automotive and aerospace technologies to consumer electronics. Magnetic sensors measure the magnetic field of objects and can sense linear and rotational motion, as well as positional changes. Magnetic sensors are available in various forms, such as linear, compass (ICs) and even Hall effect sensors.

KMZ43T,118 Magnetic Sensor – An Overview

The KMZ43T,118 magnetic sensor is an integrated over-temperature, linear Hall effect device which operates at a supply voltage of 4.5 to 24V DC. The linear characteristics of the sensor allow it to sense the directions of the field in both positive and negative directions and provide an output voltage proportional to its applied field. The output range of the device is from 0V to 5V, and is used for applications which require a digital or analog output.

KMZ43T, 118 Applications

The most common applications of the KMZ43T,118 magnetic sensor include position sensing, angle sensing, speed sensing, current sensing, temperature sensing and power inverter control. The sensor can be used to measure the angular position of an object, such as a stepper motor, as the values vary with the applied magnetic field. It can also be used for speed sensing in electric fans, pumps and other rotating components. As its output voltage varies depending on the applied magnetic field, the sensor is also used for current sensing and temperature sensing. The device can also be used for power inverter control, as the output signal can be used to switch the inverter on or off depending on the magnetic field applied.

Working Principle of the KMZ43T,118 Magnetic Sensor

The working principle of the KMZ43T,118 magnetic sensor is based on the Hall effect. As the name implies, the Hall effect occurs when a magnetic field is applied to a conductor. The conductor, in this case, is usually a semiconductor, such as a transistor. When a magnetic field is applied to the semiconductor, a Hall voltage is generated which is proportional to the applied field. This Hall voltage is then used to measure the magnetic field, and the output depends on its magnitude.

Advantages of Using the KMZ43T,118 Magnetic Sensor

The KMZ43T,118 magnetic sensor offers several advantages over other types of magnetic sensors. One of the main advantages is its higher sensitivity, as it can measure changes in magnetic fields as low as 1 mT. Additionally, the device has a wide operating voltage range and can measure both positive and negative fields. Its response time is also very quick, allowing it to detect changes in the magnetic field almost instantaneously. The low power consumption of the device makes it suitable for use in low-power applications, such as those found in consumer electronics. Finally, the device is very cost-effective, making it a popular choice for industrial and consumer applications.

Conclusion

The KMZ43T,118 magnetic sensor is a very versatile device which can be used for a variety of applications. Its wide operating range, sensitivity and low power consumption make it suitable for use in consumer electronics, automotive and industrial applications. With its linear characteristics, it is possible to measure both positive and negative magnetic fields. The device is also very cost-effective, making it a popular choice for many applications.
