Guide to Selecting a Connector
In selecting a connector, it first must be
determined if a non-environmental (97
A/B Series) type or an environmental
(97E) type is required.

These two questions are important,
because they indicate which insert you
need. There are literally hundreds to
choose from.
contact connectors are illustrated on
pages 8-13. The inserts most often
used are highlighted on these pages.
an insert arrangement. Say you want to
connect eight 16-ga. wires, - first find
the section of arrangements contain-
ing 8 contacts. Insert number 20-7 is
the one you want because it contains
eight 16-ga. contacts and it is one of
the most often used. The one you
choose might depend on your space or
voltage
capacity of each insert is listed under
its diagram.
to connect, the method is essentially
the same. Actually, the insert configura-
tions for multiple-size wires are a lot
more flexible than they appear. That’s
because you can always solder a
smaller wire to a larger contact. How-
ever, soldering a large wire to a small
contact isn’t recommended because of
size and current requirements.

Here’s a situation to watch out for. You
have four identical receptacles on a
panel. One carries high current loads.
The others have low current functions.
A plug mated with the wrong receptacle
(cross-mating) could ruin your valuable
equipment.

For Wall Mounting Use a wall recep-
tacle, type 3100. The elongated back of
this receptacle extends through thick
wall material. It is threaded to accept
standard hardware fittings.
For Unmounted Applications Use
the cable receptacle, type 3101.
For Box or Panel Mounting Use the
box receptacle, type 3102. This recep-
tacle’s back is short to conserve space.
It is not threaded on the back end and
is used when no accessories such as
clamps are needed.

For ordinary situations The straight
plug, type 3106 meets most connector
requirements. However . . .
when space is critical you may want
to consider using an angle plug, type
3108. This type plug lets the cable
enter your equipment at a right angle.

You can get both straight and angle
plugs in solid or split back shell
designs. With the solid shell you have
greater strength and you save space.
On the other hand, the split shell
design lets you quickly inspect the sol-
der terminals when you need to. This
feature could be important if you’ll be
subjecting the connector to rough han-
dling and heavy use.
shell construction in an non-environ-
mental type is the letter A. For a solid
shell construction in the 97E environ-
mental sealing type the designation is
E. This designation letter goes immedi-
ately after the main shell type number:
for example, 3106A or 3108A.

detail on pages 5-21. If a crimp type connector is needed, the same
steps apply, however, you should consult pages 22-31 for details on
