Thru 0.250 [6.35] HOW TO ORDER A20 WA20 MODEL P BODY STYLE AB CONTACT LOCATION A EMPTY CONTACT POSITIONS 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). 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). www.vishay.com 2 Document Number 36018 Revision 18-Jul-00 |
