D-Sub Receptacle for Board-Edge I/O
The TE Connectivity AMPLIMITE HD-20 5747844-5 is a 9-position D-Sub receptacle in the standard DE (E) shell size, arranged in 2 rows. The mating-side flange carries female screwlocks (4-40 thread) for a vibration-resistant mate with the corresponding male D-Sub plug.
Current and Voltage — Signal-Density Duty
The 6A per-contact rating is typical for the HD-20 series and reflects the contact size and pitch; for higher current per circuit, a high-density or power D-Sub variant would be needed. The 125V rating covers most low-voltage industrial control and data-communication interfaces.
The shell is steel with a tin-plated finish, providing EMI shielding when mated with a complementary D-Sub plug.
