It is a through-hole solder connector, vertical orientation, designed for board-to-cable termination in serial data, instrumentation, and control signal paths. The 6 A per-contact rating and 125 V voltage ceiling place it squarely in the signal interconnect class, though the gold-plated brass contacts and steel shell with grounding indents give it the shielding and corrosion margin for industrial or lab environments where repeated mating and EMC matter.
What the 6 A Rating Means for the Fit
The 6 A per-contact rating is the standard current ceiling for a 9-position D-Sub signal connector.
Grounding and Shell Construction
This is a real differentiator for noisy environments — the shell provides a low-impedance path to chassis ground, and the female screwlocks (4-40) on the mating side hold the pair together under vibration, keeping the ground continuity stable.
