Rectangular connectors refer to the shape of connection. Headers, male pins, and board-to-board connectors are some common connection products that use a rectangular shape. D3408-5202-AR is a type of rectangular connector – specifically, a header with male pins. In this article, the application field and working principle of the D3408-5202-AR will be examined.

Application Field

The D3408-5202-AR is a commercial grade, standard connectivity product, designed primarily for use in telecommunications applications. It is suitable for use in connections from high speed digital streams to high voltage power lines in low power circuits. The design also makes the connector suitable for low frequency and low power applications. It is often used in applications such as data and power transceivers, LAN switches, routers, power over Ethernet (PoE) modules, radio frequency (RF) transmitters, and more.

Furthermore, it can be used in a variety of industries, including automotive, consumer, industrial, medical, military, and aerospace. The use of the connector in these industries could include wiring harnesses, servicing and installation, custom applications, and use in many other products.

Working Principle

The D3408-5202-AR is a header with male pins, meaning that the connecting pins are exposed, and the socket – or female contacts – are contained in the insulation material. The connector consists of two rows of 2mm-pitch pins, with a housing that improves polarization, allowing a secure connection to the target board. This ensures that the connecting pins do not make contact with other pins and short circuit, potentially damaging the board.

The pins are polarized, designed to prevent the connector from being inserted backwards. This is achieved by designing the connector so that the pins on one side are slightly longer than those on the other, meaning that the connector can only be inserted in one direction. In addition, the housing of the connector is designed with grooves which prevent the connector from being inserted incorrectly.

The D3408-5202-AR also has a clamshell design, meaning that the housing is divided into two pieces, which can be opened and closed to access the pins. This allows for easy and secure connections to be made without requiring tools. The connector also has a catch mechanism, which holds the housing tightly together, making sure the connection remains secure during vibration and strain.

The D3408-5202-AR is also designed to meet typical temperature and environmental standards, meaning that it is suitable for use in a range of environmental settings. It is UL listed, meaning it meets safety standards, and it is RoHS certified, meaning it meets certain recycling standards.

Conclusion

The D3408-5202-AR is a header with male pins, designed for telecommunications applications, and suitable for use in a variety of industries, including automotive, consumer, industrial, medical, military, and aerospace. The connector is designed with two rows of 2mm-pitch pins, a housing that improves polarization, and a clamshell design for easy access and secure connections. It is UL listed and RoHS certified, meeting safety and recycling standards. Thanks to its robust design and configuration, the D3408-5202-AR is a reliable and secure connector for a range of applications.
