Description
Moisture Resistant
Fluid Immersion
Immersion
MIL-STD-1344
Method 1002.1 Type II
1. No deterioration of performance.
2. Insulation resistance greater than 100 megohms
3. No evidence of flashover or breakdown during 1000 VAC
DWV testing.
1. No detrimental damage.
2. Able to meet requirements of mating and unmating
forces test.
While still immersed, the mated connectors exceeded 100
megohm insulator resistance and exhibited no evidence of
breakdown or flashover during 1000 VAC (RMS) DWV
testing.
20 hours immersion in hydraulic fluid per MIL-H-5606
and lubricating fluid per MIL-L-23699
Two hour Immersion tap water at a dept of 36.00
(914.40) in mated condition, per MIL-STD-810

GD* pin connectors are available wit pre-loaded,
non-removable contacts for P.C. board termination.
Typical Part No. GDB-25PB. Environmental sealing
is accomplished by application of epoxy to each
contact cavity, interfacial seals, and bonded con-
nector components.
GD* connectors meet all applicable requirements of MIL-C-24308. The following are excerpts form
ITT Cannon Test Report C82-78 applicable to environmental D subminiature GD* series connectors. Refer
to MIL-C-24308 Test Extracts on page 385.
