Terminal Blocks - Headers, Plugs and Sockets is one of the most widely used components in a variety of electrical engineering products, from consumer electronics to industrial control systems, and V70402500000G is a typical product within this series. This article introduces the application fields and working principles of V70402500000G.

V70402500000G is a kind of terminal block with 5.08mm pitch used for connecting several circuits in a PCB. It is widely used in current industrial control systems, power supplies, choppers, etc. Its working either meets the requirements of UL 94V-0 flame resistance or achieves excellent protection from pressure and vibrations. The product is RoHS compliant and exhibits excellent flexibility in terms of cable additional and removal​.

The application fields of V70402500000G include:

• Industrial control systems - V70402500000G is commonly used in industrial control equipment, such as servo drivers and drives, motor controllers and motors, frequency converters, switchgear, etc. By connecting the related circuits between the same type of products, the internal connection is simplified, which significantly reduces the installation time.
• Power supplies - V70402500000G is also used in the power supply field, such as DC-AC inverter, UPS, solar inverter, PV system, etc. With the reliable connection of the terminal blocks, the circuit wiring is improved, which can effectively shorten the time and reduce the risk.
• Choppers - V70402500000G is usually used in choppers, such as IGBT modular choppers. Its high pressure resistance and excellent temperature stability make it suitable for the use of choppers with high frequency and current.

The working principle of V70402500000G is quite simple. Inside the terminal, there are series of pluggable metal contacts. These contacts are linked at one end and open at the other end. When operating, one cable should be inserted into the open end of the contact. Then the connection part should be pressed and adjusted to make it tight without gaps. This metal contact connection ensures a reliable and safe connection between the cables and the terminal.

In conclusion, V70402500000G is a popular terminal block for connecting several circuits in a PCB. It is useful in various industries, such as industrial control, power supply and chopper. Its working principle is also fairly straightforward and simple.
