HM2H41P1LF

Backplane connectors are used to interconnect multiple circuit boards or other electronic system components. Backplane connectors are made up of either one or two components; housings and headers, and they use a variety of coupling systems. Let’s take a look at the HM2H41P1LF housing from Hirose, and how it is used in the backplane connection market.

Description

The HM2H41P1LF is a housing for a Hirose backplane connector. It consists of (2) plastic parts and (2) metal covers, which permit the use of short and tall standoffs for mounting. This housing can be used to support single- or double-sided backplanes, and is available with a 0.6mm profile option as well as an economy 0.5mm profile option.

The HM2H41P1LF housing has a total of 55 contacts. It is rated to 3.5A per contact, and has a rated current of up to 175A. This housing also supports high-speed data transmission, with 2Gbps of throughput.

Applications

The HM2H41P1LF housing is designed for the interconnect of backplanes. It is particularly suitable for use in industrial computers, telecommunication systems, automotive electronics and robotics applications.

Due to its high current ratings and low profile, the HM2H41P1LF housing is the perfect solution for high-density backplane designs. It can also be used in applications where there is a need for a high number of differential pairs, as it is able to support up to 50 differential pairs.

Working Principle

The HM2H41P1LF housing is a two-part assembly. The first part is a housing with two walls, one of which can be opened to provide access to the interior space. The second part is a header, which has two rows of pins that insert into the housing. These pins are what actually make the electrical contact with the backplane.

The two parts are then firmly held together by a latch mechanism. This provides a secure and reliable connection that will protect against vibrations and shocks. Additionally, the latch ensures that the connection remains secure even if the two parts are moved relative to each other.

Lastly, the HM2H41P1LF housing has a metal cover which provides protection against EMI/RFI interference. The metal cover is attached to the housing using a spring latch, which helps to minimize the risk of electrostatic discharge in high-noise environments.

Conclusion

The HM2H41P1LF housing from Hirose is a robust and reliable solution for backplane connectors. It is designed for a wide range of applications, including industrial computers, telecommunication systems, automotive electronics and robotics. Its high current ratings, low profile and support for up to 50 differential pairs make it the perfect choice for high-density backplane designs. Additionally, its latch mechanism ensures a secure connection, and its metal cover adds protection against EMI/RFI.
