General information
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 guiding system, which also
reduces the potential danger of damaging
cardswhenbeingforcedintoflexingracks.
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.
The tooling can be ordered with the part
