The TE Connectivity 5749014-1 is a 9-position D-sub plug from the AMPLIMITE HDP-20 series, fitted with male pins and a solder termination for through-hole mounting. It's the standard DB-9 density layout — the shell size is 1 (DE, E) — so it mates with any matching DE-9 receptacle housing. The black UL94 V-0 rated thermoplastic shell carries grounding indents on the steel shell to bleed shield current before it reaches the signal pins, which cuts down on EMI coupling in noisy environments like industrial control cabinets or test equipment racks.
Rated 6 A per contact at 125 V — that's typical for signal-grade D-subs, not for power distribution.
