HIVAC
®
Series Connectors are feedthroughs equipped
with D-Subminiature Adapter Connectors for SPACE or
INDUSTRIAL vacuum applications.
The HIVAC
®
Connector configuration requires three
separate units to function properly. The center unit is the
feedthrough. This feedthrough requires two adapter units,
one for the atmospheric side and one for the vacuum side.
Both sides of the feedthrough contain four threaded
mounting holes and an o-ring groove. These redundant
features allow either side of the connector to be mounted
towards the vacuum, giving the customer the ultimate in
flexibility.
The feedthrough has always Female/Female contacts.
The contact type of Adapter Connector is always as male
next to the feedthrough and the other sides are according
to the Customer request, Male/Male or Male/Female for the
normal density, and for the high density it is systematically
Male/Female.
A feedthrough has 5 types of insulators: 37 or 50 contacts
for normal D and 44, 62 and 104 contacts for high D.
An Adapter Connector allows several combinations with a
feedthrough.
The advantage of this system is that it allows the user the flexibility
to purchase a single feedthrough and use it with a variety of
adapters.
HIVAC
®
series connectors utilize precision machined contacts for
strength and durability. The female contact features a rugged
"Closed Entry" design having a brass shroud. The materials and
finishes, as well as the technical characteristics of the HIVAC
®
series connectors, conform to MIL-DTL-24308, Goddard and
SPACE-D32 specifications.
All HIVAC
®
Series connectors are 100 % leak tested after
fabrication.
