ORDERING INFORMATION

P
AB
A
MODEL
BODY STYLE
CONTACT LOCATION
EMPTY CONTACT
POSITIONS
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).
Specify by contact
identification letter
(A, B, etc.) any contact
positions which are to be
left empty (omit, if none
required).
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).
Side Mount with 4 positions
for #20 AWG contacts.
EXAMPLE 1:
A20P-CD or WA20P-CD = Connector with
pin contacts in positions “C” and “D” and
socket contacts in positions “A” and “B”.
