78. INSERT ARRANGEMENT. The insert arrangement
is number and size of contacts available by shell size
(Table 1). Insert arrangements are specified in
MIL-STD-1669.

configuration is the manner in which contacts are
placed within insert in a standard configuration. All
arrangements identified in Table 1 are illustrated
(Figure 6).
80. CONTACTS. Contacts are designed to prevent
damage to contact retention device or sealing member
during insertion or removal of contacts.
81. Fixed Contacts. Contacts in hermetically sealed or
thru-bulkhead receptacles are fixed non-removable,
and solderable, or feed through.
