SCOPE
•
•
Recommended cable preparation
Recommendations on wire types that may be terminated.
No deviation of wire size, insulation type or insulation thickness from those listed in section
“Recommended
Wire Sizes and Insulations”
should be used without approval of the FCI engineering
design group responsible for this product. Please refer all question to your local FCI representative.
Recommended requirements on completed termination

GENERAL
3.1
Method of Specifying
The cable assembly and detail drawings should reference this specification when applicable. All
exceptions to the requirements of this specification should be clearly described in the notes of the cable
assembly drawing. We do not recommend any exceptions unless approval is obtained in advance from
the FCI engineering design group.
3.2
Workmanship
Workmanship shall be of a level that indicates controlled conditions of manufacture such that subsequent
operations, functionality and performance are not degraded.
3.3
Usage
The connectors 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 and IEC-61076-4-110.
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.

Product Descriptions
4.1
72476 type 4-row Metral™ Unshielded Connector
This connector is a 4x6 2mm pitch cable connector with IDC type contacts. The connectors are sold in
kits with the following variations.
as 72476-wxy1 where
“w” specifies the plating on the separable contact
“x” specifies the latch finger type
w = 1 , for 0.8um Gold
x = 1 , for cable diameters up to 7.0mm
w = 2 , for 2.0um Gold
x = 2 , for cable diameters up to 11.0mm
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
Figure 1 4x6 Unshielded Connector
Product Number
72476-w1y1
Product Number
72476-w2y1
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.
