Note: To determine connector overall
length (Dim. A), multiply .156 x the
number of circuits. Example: .156 x
10 circuits equals 1.560 inches

Information
The “Base Part Numbers”
Chart above shows the base
part number and number of
circuits available for the
described connectors.
Prefixes and suffixes are deter-
mined by the number of circuit
positions in the connector. For
example, the complete part
number for a 10-position
closed end connector with
locking ramp and without
polarizing tabs for 18 AWG
wire would be:
The set of numbers in bold face
