HIF4-40P-3.18DS Datasheet/PDFHIF4-40P-3.18DS is a type of rectangular connector belong to the category of headers, male pins. It has a particular set of applications that will be explored in the next section.
The HIF4-40P-3.18DS is most commonly used in high-speed applications where space is a concern. Its small size and low profile makes it ideal for use in limited spaces and tight places like cabinets, enclosures and computers.
It features a 40-pin design with a 3.18mm row-to-row pitch along with a 0.5mm pin pitch. This makes it ideal for connecting essential components in the data pathway, including server and data center backplanes, storage disk drives, and computer motherboards. It is also suitable for use in a broad range of data transmission applications including Ethernet, audio-visual, and broadcast.
The connector is available in an insulated version that is made up of either a glass-filled polyester base or thermoplastic. This version features several advantages including optional color coding, EMI shielding, improved reliability, interference protection, and a high degree of weather resistance. Furthermore, it is also extremely easy to install.
The operation principle of the HIF4-40P-3.18DS connector employs a dual-beam, secure holding pressure design in order to achieve reliable connection and full retention. The contact pairs on either side reciprocally hold the mating connector very accurately and securely.
Their structure is formed of an integral spring that is nested within the connector and achieves the holding pressure through the head of the contact when the contact is inserted into the yet-unmated connector. By meeting with the mating contact above the head, the near end of the spring is compressed and a force is exerted on the head from both sides of the contact, thereby providing a secure connection.
The contact itself is held in place through a combination of magnetic fields. In this way, the contact can easily be inserted and removed, and the contact\'s placement will always possess an optimal level of retention.
