• Manufacturer: Defense Supply Center

e. Contact styles:
(1) Contact designators for connectors using standard contact arrangements as indicated in
The connectors that accommodate crimp removable contacts (P, S, H, and J) may be ordered
without standard contacts by adding an appropriate note on the purchase order; however, the
connector Part or Identifying Number (PIN) and the marking requirements remain unchanged
(see 3.4.1.1, 3.43, and 6.2).
Series I and II finishes:
Series III and IV classes:
The P, S, H, J, X, Z, or C designators are used to indicate that connectors will be used with full
compliments of the applicable standard contacts as indicated in MIL-STD-1560.
MIL-STD-1560 are as follows:
A - Silver to light iridescent yellow color cadmium plate over nickel (conductive)
B - Olive-drab cadmium plate over a suitable underplate (conductive) -65 C to +175 C.
C - Anodic (nonconductive) -65 C to +200 C.
D - Fused tin, carbon steel (conductive) -65 C to +150 C.
E - Corrosion resistant steel, passivated (conductive) -65 C to +200 C.
F - Electroless nickel coating (conductive) -65 C to +200 C.
N - Hermetic seal or environment resisting corrosion resistant steel (conductive plating)
R - Same as F, but higher corrosion requirement.
U - Same as A, but higher corrosion requirement.
X - Same as B, but higher corrosion requirement.
C - Anodic (nonconductive) -65 C to +200 C.

G - Same as F but space grade.
H - Same as Y but space grade.
J - Olive-drab cadmium plate, composite, (conductive) -65 C to +175 C.
K - Corrosion resistant steel passivated (conductive) -65 C to +200 C.
M - Electroless nickel coating, composite, (conductive) -65 C to +200 C.
N - Corrosion resistant steel with electrodeposited nickel plating (conductive)
R - Same as F, but higher corrosion requirement.
S - Corrosion resistant steel with electrodeposited nickel plating (conductive)
W - Olive-drab cadmium plate over a suitable underplate (conductive) -65 C to +175 C.
X - Same as W, but higher corrosion requirement.
