PURPOSE
This specification defines the performance, test, quality, and reliability requirements for the 72476-X0Y and 74894-NNN 4x6
and the 72477-X0Y and 74896-NNN 4x12 Unshielded Cable Connectors.
SCOPE
This specification is applicable to qualification testing of the 72476, 72477, 74894 and 74896 type Cable Connectors used in
conjunction with standard 4-Row Metral™ Unshielded Headers.
GENERAL
3.1.
Design and Construction
Connectors, Covers and Headers shall be of the design, construction and physical dimensions specified on the
applicable product drawings. The cable connector and header shall be capable of mating without any degradation in
performance.
Workmanship
Workmanship shall be of a level that indicates controlled conditions of manufacture such that subsequent operations,
functionality and performance are not degraded.
Usage
The connectors and headers covered by this instruction are intended for use in a wide variety of environments and are
designed to meet the conditions specified in Bellcore GR-1217-CORE.
Banned/Restricted Substances
All product where the part number ends in ‘LF’ meet the European Union directives and other country regulations as
described in GS-22-008. The part numbers that do not end in ‘LF’ meet all regulations except for Pb in SnPb plating.
Manufacturing Processability
All products covered by this specification will not withstand exposure to convection, infra-red or vapor phase reflow
ovens. Do not heat this product above 110°C.
3.4.
Visual
Visual examinations shall be performed with a magnification of up to 10x. (8 to 10x recommended)

4.1.
72476 type 4-row Metral™ Unshielded Connector
This connector is a 4x6 2mm pitch cable connector with IDC type contacts. The connectors have the following
variations.
as 72476-wxy1 where
“w” specifies the plating on the separable contact
w = 1 , for 0.8um Gold
w = 2 , for 2.0um Gold
w = 3 , for 1.3um Gold
w = 9 , for 0.8um GXT
“y” specifies the wire gage capacity
y = 1 , for 26-24 gage wire
y = 2 , for 30-28 gage wire
“x” specifies the latch finger type
x = 1 , for cable diameters up to 7.0mm
x = 2 , for cable diameters up to 11.0mm

Standard Latch Finger
Short Latch Finger
The difference between the standard latch finger ( x = 1 ) and the short latch finger ( x = 2 ) is that the
standard latch stands above the cable tie and is easier to access but thus restricts the maximum diameter
cable that can be used. In certain cases the use of multiple cables or the stripping of the cable jacket above
the cable tie area of the connector will allow the user to overcome some restrictions.
