The TE Connectivity 5747301-7 is a 37-position D-sub receptacle from the AMPLIMITE HD-20 series. It carries 2 rows of female sockets on the standard DC (C) shell size — the same shell used for 37-pin D-subs across the industry. Rated 6A per contact at 125V, it handles signal-level current and low-power interconnects inside enclosures, not bus-level power.
What the 6A and Gold Flash Mean for Real Use
The gold flash (thin gold over nickel on phosphor bronze) provides corrosion resistance for the first few mates. Rated 6A per contact.
The shell size 4 (DC, C) layout is industry-standard for 37-pin D-subs — the footprint and pinout are interchangeable with other manufacturers' 37-position D-subs of the same shell size. The steel shell with tin plating provides basic EMI shielding when the mated pair is grounded through the mounting hardware.
