Guiding system Identification Part number Guide pin 17 79 000 0080 Receptacle for guide pin 07 73 000 0280 Dimensions [mm] Guide pin Receptacle for guide pin Board drillings (View-X) The guide pin solution from HARTING allows safe mating under sometimes extreme conditions. This might be large and heavy boards that bow under their own weight. Also insufficiently aligned or worn out rack systems can be tolerated better with the use of HARTING's g uiding system, which also reduces the potential danger of damaging cards when being forced into flexing racks. har-bus HM 4) General information The guide pin and receptacle's design solution allows to overcome a 3 mm [.118'] offset between the backplane and the mating daughtercard. The reducing diameter of the pin (from 4.85 mm to 3.4 mm) ensures that its positioning task is smoothly transferred to the connectors as soon as they start to engage. Finally the thin diameter section of the guide pin is no longer positioned by the ferrule of the receptacle, ensuring that the pin is able to freely follow any movement imposed by the engaging connector. This ensures that there is no static stress between the connectors and the guiding system. The rugged metal designed guide pin is screwed to the backplane with standard hexagon screws. Whereas the molded receptacle is designed with four press in pegs that can be installed to the board together with the connectors.
