EMPTY CONTACT
POSITIONS
Specify
by
contact
identification letter
(A, B, etc.) any contact
positions
which
are to
be
left empty (omit, if none
required)
Side Mount
with
4 positions
for #20 AWG contacts
P - Designates pin style
body.
S - Designates socket style
body.
These designations are
used
to
identify mating connectors, however,
any combination of pin and socket
contacts may
be
ordered in either
style
body.
Therefore,
when
designators 3 and 4 are the same,
a connector designated A20P or
WA20P will
mate
with
a connector
designated A20S or
WA20S.
Example:
A20P-CD mates
with
A20S-CD
A20S-AB mates
with
A20P-CD
Designates pin contact
positions in an A20P or
WA20P
connector or socket
contact positions in an A20S
or
WA20S
connector
(specify “A”, “B”, “C”, “D” or
any combination of the four)
EXAMPLE 1:
A20P-CD or WA20P-CD
= Connector
with
pin contacts in positions “C” and
“D” and socket contacts in positions
“A” and “B”
EXAMPLE 2:
A20S-CD or WA20S-CD
= Connector
with
socket contacts in positions “C”
and “D” and pin contacts in positions
“A” and “B” (would mate
with
Example 1
at left)
EXAMPLE 3:
A20P-BC or WA20P-BC-A
= Connector
with
pin
contacts in positions “B” and “C”,socket contact in
position “D” and no contact in position “A” (would
mate
with
A20S-BC or
WA20S-BC-A)
