GENERAL SPECIFICATION FOR
This specification is approved for use by all Departments and Agencies of the Department of Defense.
1. SCOPE
1.1 Scope. This specification covers multicontact connectors for 1/16, 3/32, and 1/8 inch printed wiring boards, and
for interconnections between printed wiring boards. The connectors are intended to provide a reliable connection
between printed wiring and conventional wiring. The interconnector concept is intended to provide connection of printed
wiring on one board to printed wiring on another board.
1.2 Classification. Connectors covered by this specification are classified by physical characteristics as indicated by
type, style, class, size, and mounting provision (see 3.1).
1.2.1 Type. The type is identified as follows:
Types A and AD (card insertion connectors). Connector receptacles containing two contacts within each contact
cavity, each of which engages a contact on an opposite side of a printed wiring board. In type A connectors, the two
contacts in each cavity are electrically common. In AD connectors, the two contacts in each cavity are electrically
isolated from each other.
Type CR (receptacle). Composite connector having a solder type or removable crimp type female contact inserted
into and mechanically retained in a receptacle housing, or composite contacts mounted on individual intermating printed
wiring boards. Type CR contacts mate with type CS contacts.
Type CS (adapter). Composite connector having individual contacts attached to a printed wiring or retained in an
assembly attached to a printed wiring board. Type CS contacts mate with type CR contacts.
1.2.2 Style. The style of the connector is identified by a two-digit number which signifies the number of contact
positions in the connector.
1.2.3 Class. The class is identified by a single letter symbol which denotes the kind of termination as specified in
table I.
