Backplanes and interface PCBs use more and more DIN 41612/IEC 60 603-2 and 2,0 mm HM press-fit connectors. Because of this the use of D-Sub high power connectors with solder terminations has a serious cost impact, says Erni.
Erni developed its high power D-Sub press-fit connector series to provide an economical solution to the high cost of solder termination. This connector series allows more economical and reliable assembly on the backplane, since press-fit technology has a significantly lower failure rate than solder technology.
Pin configurations are available in 3W3, 3WK3, 5W5 and 8W8 which may be loaded with a maximum of 3, 5 or 8 male/female high power contacts. Part loadings are also available upon request.
Benefits of pressfit are: gas-tight, corrosion-proof and mechanically strong connections; nonpolluting - no use of cleaning, flux or solder media; no thermal stress on the PCB.
For cable termination solutions, either the KSG200 cable connector housings with superior EMI/RFI shielding or the KSG183 and KSG185, can be used for good ESD protection.
