MIL-C-26500
Hermetically Sealed Connectors

sealed connectors meet or exceed the require-
ments of MIL-C-26500. The 8521/8602 series
are dimensionally equivalent to MS27034 and
MS24265 respectively. The 8503/8603 has the
same mounting dimensions as MS24264.
MIL-C-26500 does not specify the shell materi-
al, nor does it specify the plating for the shell
and contacts for hermetic class connectors.
Sealtron offers as standard connectors, cold
rolled steel shell plated fused tin, 300 Series
passivated stainless steel shell, or300 Series

let or solder pot contacts with fused tin plating
are offered as standard. Other contact styles and
plating combinations are available for your spe-
cific needs.
