Resonators serve as an integral component for many circuits, due to the nature of their usage in certain applications. Many manufacturers provide Resonators suited for particular applications, and EFO-P4004E5 is one of them. This paper will describe both the application field in which EFO-P4004E5 fits, as well as its working principle.

Application field: EFO-P4004E5 is a type of resonator among numerous others, which is well suited for frequencies in the range of 60 kHz ~ 70 kHz. Since they produce a particularly strong effect in the said frequency range, they are primarily used in various sensing devices such as proximity, pressure and temperature sensors, as well as infrared detectors. The resonator is also used in some audio-related applications.

Working principle: The resonator works on the principle of electromagnetism. An electromagnet is formed when two or more coils of wire are placed together and current is sent through them. These coils create a magnetic field which is capable of oscillating at a certain frequency determined by the geometry of the coils and their magnetic properties. This oscillation, when applied to a sensitive material such as piezo-electric material, can cause the material to generate a charge in response which can be used to build a circuit.

EFO-P4004E5 uses this phenomenon to create a resonator which generates a specific frequency in the range of 60 kHz ~ 70 kHz when an electric current is passed through the device. It is made up of two coils of wire placed in close proximity to each other, and is connected to a piezo-electric material to produce a charge in response to the oscillating magnetic field. As the current is adjusted, the frequency of the magnetic field, and in turn the frequency generated by the piezo-electric material, can be modified to suit the desired application.

The particular characteristics, as well as the wide application field of EFO-P4004E5, make it a highly useful resonator, and one that is particularly suited for several types of sensing devices and audio-related applications. Its working principle is simple yet effective and very reliable in operation, making it the perfect resonator for the purpose.
