Contact Preparation Instructions
I.
Crimp Tools:
1.
M22520 Series is recommended. See Tool Table in
catalog, for choice of turret head and selection setting
according to contact size, part number and wire gage
size.
2.
Setting Up and Operation: Consult Tool Manufacturer.
II.
Wire Preparation and Crimping
1.
Strip wire to required length. (See Figure 1). When
using hot wire stripping do not wipe melted insulation
material on wire strands; with mechanical strippers do
no cut or nick strands.
Figure 1
2. See Table 1 for proper finished outside wire dimensions.

**Min. diameters to insure moisture proof assembly; max
diameters to permit use of metal removal tools. Twist Strands
together to form a form bundle.
3.
Insert stripped wire into contact applying slight
pressure until wire insulation butts against wire well.
Check inspection hole to see that wire strands are
visible. If there are strayed wire strands, entire wire
end should be re-twisted.
4.
Insert wire and contact into crimping tool as far as
possible. Crimp contact wire well.
III.
Contact Insertion and Removal
1.
When inserting or removing contacts, first remove
securing devices and slide devices over wires in
proper sequence
2.
Consult Tool Table, in catalog, for correct insertion or
removal tool (metal or plastic) according to contact
size.
3.
Insertion:
a.
Slip correct size tool (with plastic tool, use colored
end) over wire insulation and slide forward until tool
bottoms against rear contact shoulder. Contact must
be aligned with grommet hole and not inserted at an
angle. Push forward until contact is felt to snap into
position within insert. Remove tool, holding forward
on the wire in order to prevent contact from being
dragged back with tool. Gently pull each wire to
ensure contact is properly seated.
b.
Uncrimped Contacts and Sealing Plugs: Fill in
unused holes with an uncrimped contact. Follow with
a teflon sealing plug, small diameter first, so that one
end protrudes out the rear of grommet. See Table 2
for sealing plug application data. (Optional insertion
of large end first is possible, but not recommended).
