Type 'SMA' connectors feature a Threaded Coupling design similar to
Type 'TNC', Type 'N', and Type 'F' connectors.

3.1.2 D-Subminiature Cable Connections

Type 'D' Connection Type
Chassis Receptacles:
Type 'D' Cable with Jack Screws
D-Subminiature connectors are also called Type 'D' or 'D-Sub' connectors. The connector pair
features multiple rows of pins (male side) coupled to mating sockets (female side). The cable plug
and chassis receptacle each feature a D-shaped profile that interlock to ensure proper pin
orientation and connector seating.
Either chassis receptacle gender features two jack nuts for secure assembly of the cable plug to
the chassis receptacle.
Whether its gender is male or female, the cable plug features two jack screws for secure
connection to the jack nuts provided on the mating chassis receptacle. The jack screws may be
hand tightened or tightened with a standard flat-blade screwdriver.
Connection Instructions: Orient the plug to the receptacle in the proper position. Press firmly
into place. Use the jack screws to secure the plug to the receptacle jack nuts. Do not over-tighten.
About connector pinout tables: Figure 3-2 identifies the Pin 1 location for either gender
connector. Unless noted otherwise, the connector pinout tables provided in this manual
arrange/order information (i.e., the Pin # column/row) based on this orientation.
