Contact resistance
Rc initial <26 mOhm @2.5 A / Rc
after salt spray <28 mOhm @2.5 A
Rc initial <15 mOhm @3 A / Rc after
salt spray <18 mOhm @3 A meets MIL-DTL-24308G
Contact Engagement and
separation forces (initial)
Engagement Force: 1.67 N max /
Separation Force: 0.14 N min
Engagement Force: 3.33 N max /
Separation Force: 0.19 N min meets MIL-DTL-24308G
Mating/Unmating forces 10 ozf * nb of contact Depending on shell size (unknown)
Unknow shell size to define
requirement of MIL-DTL-24308G
Temperature Cycling
EIA-364-32, condition I, 5 cycles,
except that the maximum
temperature shall be 125 °C
EIA-364-32, condition I, 5 cycles,
except that the maximum
temperature shall be +125 °C meets MIL-DTL-24308G
Humidity
EIA-364-31, method IV with
Optional Step 7a-7b
EIA-364-31, method IV full
sequence required
Step 7a-7b not tested buexpected to
conform with MIL-DTL-24308G
Vibration EIA-364-28 cond IV EIA-364-28 cond IV meets MIL-DTL-24308G
Shock EIA-364-27 cond E EIA-364-27 cond E meets MIL-DTL-24308G
Durability 500 cycles 500 cycles meets MIL-DTL-24308G
Salt spray EIA-364-26 cond B EIA-364-26 cond B meets MIL-DTL-24308G
Fluid Immersion
fluid k (coolant "coolanol", ) & d
(lubricating Oil)
EIA-364-10 fluid a (hydraulic fluid) &
d (lubricating Oil)
Fluid "a" not tested but DMM
certainly conform with MIL-DTL-
24308G

2. Insert retention 50 psi (@10 psi/s max) 60 psi (@10 psi/s max)
Not tested at 60 psi as requested by
MIL-DTL-24308G
Crimp tensile Strength depending on cable -
Not required by MIL-DTL-24308G
qualification routine
Thermal Vacuum Outgassing
maximum total mass loss (TML) of
1.0 % / maximum volatile
condensable material (VCM)
content of 0.1 %
maximum total mass loss (TML) of
1.0 % / maximum volatile
condensable material (VCM)
content of 0.1 %
not tested yet but conforms with
MIL-DTL-24308G/83513G because
of good properties of pps (but insert
glue not tested yet)
Contact retention 5 pounds min 9 pounds min
Specs of 10N min is from BS9525
standard, can't reach MIL-DTL-
24308G/83513G
