Working Principle of 59021-1-T-03-E Modules

The 59021-1-T-03-E Module is a magnetic sensor working on the principle of induction, and operating based on changes in the magnitude and direction of the magnetic field in its vicinity. The magnetic field in its radiation zone impacts the conducting coil inside the module which results in a change of electric potential in the coil. This change of electric potential is then used to control the output of the module which is either an analog or digital signal based on the type of magnetic sensor and application.

The 59021-1-T-03-E Module includes two coils, one of which is the transmitter coil and the other is the receiver coil. The transmitter coil is the one inducing the magnetic field. The amount of induced magnetic field can be adjusted with the help of adjacent potentiometers. The receiver coil then detects the changes in the magnetic field, and this information is further used by the module.

The module is designed with the capability to detect changes in the surrounding magnetic field from both short-term and long-term distance. If the field is detected from a short-distance, the coil will produce a voltage which is proportional to the angle between the two coils. This voltage is used to produce a proportional current in the module, and the current will then be used to control the output of the module, for example, to produce an analog or digital signal to a controlling system.

In applications where the field is detected from a long-distance, the module can detect a frequency change in the magnetic field and can further be used to measure the speed of the moving part or even the direction of the movement. The received frequency can further be amplified and filtered for further use.

Conclusion

The 59021-1-T-03-E Module is a versatile magnetic sensor which is used to achieve multiple sensing purposes using one single device. It can be used in various contexts for medical, industrial, automotive and security applications. It is based on the principle of induction and the module includes two coils, one of which is the transmitter coil producing the induced magnetic field while the other coil detect the changes in the field depending on the distance and further amplify the frequency. This frequency is then used to obtain the speed, presence, occupancy and position.
