Product details

The Amphenol L77SDEH09SOL2RM5C309 is a 9-position D-Sub receptacle with female sockets, part of the SD series. It uses the standard shell layout 1 (DE, E).

Rated 3A per contact at 250V, which is typical for signal-level D-Sub duty — driving RS-422 lines, low-power sensor loops, or control signals where the current per pin stays well under the limit.

Through-hole solder termination with a board-side 4-40 threaded flange — the flange lets you bolt the receptacle to a panel or bracket for strain relief, not just rely on the solder joints. The board lock feature adds mechanical retention during reflow or wave solder, and the steel tin-plated shell provides EMI shielding when mated with a grounded plug.

Frequently asked questions

What connector mates with L77SDEH09SOL2RM5C309?

This is a standard DE-9 receptacle with female sockets, so it mates with any DE-9 plug that has male pins — the same shell layout used on RS-232 cables and industrial D-Sub connectors. The 4-40 threaded flange on the board side accepts a matching jack-screw on the plug side for a secure bolted connection.
