Thru 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” www.vishay.com 21 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) For technical questions contact: [email protected] Document Number: 36018 Revision: 08-Feb-07 Legal Disclaimer Notice www.vishay.com Vishay Disclaimer ALL PRODUCT, PRODUCT SPECIFICATIONS AND DATA ARE SUBJECT TO CHANGE WITHOUT NOTICE TO IMPROVE RELIABILITY, FUNCTION OR DESIGN OR OTHERWISE.
