Make and Break Sequence
The diagram shows the sequence of
make and break for the range of 2mm
HM signal contacts, shields, Universal
Power Module contacts and DIN 41626
contacts. In relation to the key blocking
position, the housings must close by the
dimension shown to give first contact
point for the respective contact type,
with housings fully mated 9.1 [.358]
closer than the key blocking point.
All dimensions are nominals and
assume connectors are assembled flush
with the backplane.
