Introduction

The 55510-128LF is a high speed, low profile, surface mountable rectangular connector ideal for a wide range of applications within the industrial and automotive sectors. It is one of the larger sizes in the range, providing eight high speed signal contacts which meet the requirements of microprocessor or signal transmission circuits.

The Connector and Its Uses

The 55510-128LF connector is composed of a male and female connector sealed with a compression gasket, which provides excellent protection against dust and moisture ingress when mated correctly. These connectors are highly compact in design, measuring just 8.10mm by 6.57mm and having a height of only 1.33mm, making them suitable for use in space-constrained designs. The contacts are housed within a passivated base material, and incorporate a press fit retention feature to ensure a secure mating integrity. The electrical contacts are gold-plated brass which provide a cost-effective but high-quality connection.Due to its size it is most commonly used as a surface mount device for boards with a high density of components. The 55510-128LF is an excellent choice for applications such as industrial business machines, medical systems, telecommunications, automotive electronics, general consumer electronics and more.

Working Principle

The working principle behind the 55510-128LF connector is the same for all rectangular connectors. The male connector is inserted into the female connector, and the electrical contacts are established when the two are mated. As the contacts come in to contact one another, the momentum of the insert causes a latching action which securely locks the two connectors together. The contacts are positioned to ensure a low contact resistance, and they create a connection which is both reliable and protective against inadvertent disconnection. As the contacts are inserted, the gold plating ensures that they create an electrical connection with a low contact resistance.

Conclusion

In conclusion, the 55510-128LF is a reliable, low profile, high speed rectangular connector ideal for a wide range of applications in the industrial and automotive sectors. Its compact size and robust design makes it an excellent choice for those looking for a reliable and affordable connection. Thanks to its gold plated contacts, the 5510-128LF provides a cost-effective but reliable connection with a low level of contact resistance.
