EQ731L Application Field and Working Principle OverviewEQ731L is a magnetic sensor IC from TDK, designed to measure linear magnetic fields. It can detect small changes in ambient magnetic fields, making it well suited for applications including motor control, medical imaging, and other linear magnetic field measurements. This article will provide an overview of the EQ731L application field and explain its working principle.Application field
The EQ731L is designed to sense linear magnetic fields in either a vertical or horizontal orientation. It is particularly well suited for applications requiring both high resolution and low power consumption. It is particularly suitable for applications such as motor control, medical imaging, and other linear magnetic field measurements.In the field of motor control, the EQ731L can be used to accurately sense changes in magnetic fields, allowing for easy adjustment of motor speed and direction. Medical imaging applications utilize the EQ731L to obtain accurate images of organs and tissue, using a combination of linear magnetic field measurements and traditional imaging techniques. Moreover, the EQ731L is suitable for security related applications that require magnetic field changes to detect movement or presence.Working principle
The working principle of the EQ731L is based on the Hall effect. The Hall effect is a phenomena that occurs when a voltage is applied to a wire in an ambient magnetic field. The resulting electric field creates a mechanical force on the wire that is proportional to the magnetic field.When a voltages is applied to the EQ731L, it produces a hall-voltage proportional to the strength of the magnetic field it is exposed to. This resulting hall-voltage is then converted into an analog output, which can be used to measure linear magnetic fields with a high precision. Conclusion
The EQ731L is a magnetic sensor IC from TDK, designed to measure linear magnetic fields. It is well suited for applications including motor control, medical imaging, and other linear magnetic field measurements due to its high resolution and low power consumption. This article provided a brief overview of this sensor IC and explains its working principle, which is based on the hall effect.
