ORDERING INFORMATION
A20
WA20
MODEL
Side Mount with 4 positions
for #20 AWG contacts
P
BODY STYLE
AB
CONTACT LOCATION
A
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 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)
