A3A-4DA-2SV application field and working principle

A3A-4DA-2SV rectangular connectors belong to the Headers, Receptacles, Female Sockets family and are widely used in the industry due to its higher work efficiency, better insulation properties. The A3A-4DA-2SV rectangular connectors are typically used in electronic applications such as automotive, industrial, telecommunications, home appliances, computer, and consumer electronics applications.A3A-4DA-2SV rectangular connectors are commonly used in applications requiring plug and socket connectivity, electrical insulation and current switching in various communication electronic equipment, computer peripherals and automobile signaling. In a wide range of applications, they prove to be reliable and relatively cheap technology. A3A-4DA-2SV connectors have three basic parts consisting of headers, receptacles, and female sockets, with the headers being the male connectors and the receptacles and female sockets being the female connectors. The design of the header and receptacle ensures a secure connection when plugged in, which creates the optimal electrical connection. The A3A-4DA-2SV rectangular connector usually work with the usual voltage of 5V and a maximum voltage of 32V. The electrical resistance of the A3A-4DA-2SV rectangular connector is also a deciding factor depending on the kind of current flowing through the connector. A3A-4DA-2SV rectangular connectors have two pins in the female part, which can also be mounted on a PCB and used with a rectangular-shaped contact. The possible heights of the contacts are 0.2 to 5.0mm and the possible profile dimensions range from 0.5 to 2.2mm. The headers have two contacts inside a plastic molding, with the receptacles having contacts on the outside of the plastic molding. The A3A-4DA-2SV rectangular connectors are designed with a set of pins and sockets that fit together securely, allowing for easy and quick assembly. The standard features of the headers include a leg guard, a pin guard, and an insulator. The pins of the female connectors fit into the grooves on the back side of the female housing, linking the two connectors. The individual components are constructed out of robust copper alloy so that the connections are solid and the overall product life is prolonged.A3A-4DA-2SV rectangular connectors are also designed with a surface-mount technology for enhanced durability, while the receptacle incorporates a plastic shutter to protect the male parts. The connectors also include cable clips to reduce the stress exerted by the cables, thus prolonging their service life. In conclusion, A3A-4DA-2SV rectangular connectors have many advantages. They are robust, have great insulation properties, are quick and easy to install and highly reliable. They can be used in a wide range of applications, whether it’s in the automotive industry, the industrial sector, or in consumer electronics.
