78276-272HLF

Rectangular connectors, such as the 78276-272HLF, are commonly used in electronics for applications where reliable signal or power transfer is needed. They come in two basic types: headers and male pins. Both types are designed to fit securely, without causing strain or damage, and provide a safe link between two components.

Header Connectors

Headers are connectors with multiple pins for use in devices with printed circuit boards (PCBs). A header consists of a plastic insulator body with a metal contact fitted at one end. The other end of the contact has a rippled surface that seats in a PCB when the header is pressed into the board. A standard rectangular header provides two or more interconnected pins but can be configured to suit various electrical setups.

Male Pins

Male pin connectors are used on cables or other electrical components, like conduit boxes or terminal blocks, instead of directly onto a PCB. The technology used for male pins is very similar to that of headers. A metal contact with a rippled surface is fitted on one end and inserted into a plastic insulator body on the other end. This end is then pressed into a passive electrical component, creating a secure connection.

78276-272HLF Application Field and Working Principle

The 78276-272HLF is a 2-row header with nine pins in each row. It is often used for paralleling external components on a PCB, as it allows for correct matching of signal pins and prevents data errors caused by misalignment. The pins are arranged in a square pattern so they are easy to line up and slide in place, but they also have protrusions that hold them securely in place once they are locked in.

The pins are made of a corrosion-resistant material, such as stainless steel or brass, and the insulator body is composed of high-temp plastic, which ensures that it remains stable and does not melt when exposed to high temperatures. The connectors comply with RoHS requirements, meaning they will not release hazardous or toxic substances.

The 78276-272HLF connectors are sold in packs of 50, making them a cost-effective way to connect multiple components on a PCB. They are often used in telecommunications equipment, wireless networks, automotive infotainment systems, and various other electronic applications.

Overall, the 78276-272HLF is a reliable and cost-effective choice for connecting components on a PCB. It is a sturdy, corrosion-resistant connector that is designed to provide a secure and reliable connection in a wide range of applications.
