What this 25-position D-sub plug brings to the board edge
The TE Connectivity 1-5745968-6 is a 25-position D-sub plug from the AMPLIMITE HD-20 series, carrying male pins in a standard DB-25 shell layout (shell size 3). It is a through-hole, vertical-mount connector terminated by soldering the pins directly into the PCB — no crimp or IDC tooling required.
Sizing the contact plating for the reconnect duty
The gold flash contacts on this 25-position plug are rated for standard mating cycles.
Operating temperature and environment
The steel shell with tin plating provides basic EMI shielding; the grounding indents ensure the shield path is continuous through the mated pair. The UL94 V-0 polyester housing adds no smoke or flame propagation risk inside an enclosure.
