Right-Angle D-Sub for Board-Edge I/O
The 2311765-1: It uses the standard DE-9 (E-size) shell layout, so it mates with any matching DE-9 plug — the shell size is the fit, not the pin count.
Board Lock and Right-Angle Orientation
The board lock feature is a pair of plastic posts that snap into plated-through holes on the PCB, anchoring the connector during the solder process and giving the solder joints some vibration resistance once the cable is attached.
Gold Contacts and Temperature Range
Gold contact finish on copper alloy means this receptacle is built for field-service and repeated connect-disconnect cycles — the gold won't oxidize or frett like tin would in a dusty cabinet.
