402F37433CAT application field and working principle

402F37433CAT is a type of crystal structure that is widely used by a variety of industries due to its unique properties and applications. This type of crystal, also known as a Bimonte double-ended tuning fork, has a special field of application, which includes the generation of various frequency signals, synchronization and oscillation control, tilt sensing and vibration sensing. Additionally, the crystal structure can also be used in medical and telecommunications applications.

Crystal Structure

The 402F37433CAT crystal is typically composed of a two-terminal quartz crystal enclosed in a metal case. This double-ended tuning fork consists of four slender forks connected at their ends, forming a rectangular base. Each fork is composed of two identically cut quartz slabs, with the flat surfaces laid parallel to each other and the pointed ends directed outward. The flat surface is usually held at a constant negative charge and forms a diaphragm across the entire crystal.

When a voltage is applied, the diaphragm causes a voltage gradient between the two ends. The electric field across the entire crystal surface is thus strongly influenced by the applied voltage. As a result, the crystal structure vibrates at a certain frequency that is proportional to the applied voltage.

Applications and Working Principles

The 402F37433CAT crystal can be used in a variety of applications, mainly owing to its unique frequency-generating capabilities. In putative applications, it is used to generate electrical oscillations, which can be used to control the frequency of radio receivers and other electronic equipment. Additionally, it is also used as an oscillator in radio receiver circuits, or as a frequency source in telemetry applications. In medical applications, the crystal is used for timing and synchronization purposes, such as determining the heart rate and other vital functions.

The main working principle for the 402F37433CAT crystal centers around its ability to generate a voltage gradient. As the applied voltage increases, the frequency of oscillations generated by the crystal also increases. This is because the field between the two ends of the crystal increases in strength, thereby causing more resonance and higher frequencies. Additionally, due to the symmetrical geometry of the crystal, it has excellent thermal stability and can maintain a constant frequency without oscillation drift.

Advantages

The 402F37433CAT crystal offers several advantages over other crystal structures. Firstly, it has an enhanced drive performance, allowing it to be used with high input voltages of up to 18 VDC. This makes the crystal structure ideal for applications that need to produce larger-scale frequencies, such as radios and telemetry. Additionally, the crystal has excellent thermal characteristics, resulting in improved reliability and a longer operating life. Furthermore, it offers superior frequency control, allowing it to accurately generate specific frequency ranges.

Disadvantages

Although the 402F37433CAT crystal is excellent for a variety of applications, it does have some drawbacks. The primary disadvantage is its size, which makes it difficult to integrate into smaller-sized devices. Additionally, this type of crystal can be expensive to manufacture due to its intricate geometric structure.
