MIL-DTL-27599D
NOTES:
1.
A point at which gauge pin, having the same basic diameter as the mating contact and a square
face, touches socket contact spring.
2.
Distance from plug shell shoulder to locking point of coupling ring.
3.
Figure 6 applies to both plugs and receptacles.
4.
"A" initial contact with static seal.
5.
The least amount of electrical engagement occurs when the insert faces are at their minimum
interference location. When this condition exists, the coupling spring force shall be sufficient to
guarantee .024 (0.61 mm) inch compression of the peripheral sealing gasket. Minimum
electrical contact engagement is therefore computed with the peripheral sealing gasket
compressed .024 (0.61 mm) inch from its MMC position.
6.
The gauge features for GG (see main key/keyway polarization detail on figure 7) shall be .010
(0.25 mm) smaller than their MMC at basic location. (See applicable MS standards.)
7.
Three holes (design optional) equally spaced within .010 (0.25 mm) shall be provided for visual
inspection of lock when mated with receptacle.
8.
Insert front surface shall be flat within .005 (0.13 mm) TIR.
9.
Diameters F and H shall be concentric within .015 (0.38 mm) TIR.
10.
Diameter F with respect to diameter E and diameter H with respect to diameter J shall be
concentric at MMC.
11.
Diameters H and G shall be concentric within .005 (0.13 mm) TIR at MMC.
12.
Diameter W with respect to diameter V shall be concentric at MMC.
13.
Diameters U and T shall concentric within .008 (0.20 mm) TIR.
14.
Diameters CC to be concentric to diameter U within .005 (0.13 mm) TIR.
15.
Dimensions are in inches.
16.
Metric equivalents are given for information only.
