It uses the DE (E) high-density shell layout — the same footprint as a standard DE-9 shell but packed with 15 contacts in three rows instead of the usual nine in two. That extra row buys you more signal density in the same panel cutout, which matters when you are routing a harness through a crowded enclosure wall.
Contact Rating and Plating — Signal Duty, Not Power
The contacts are brass with gold flash plating.
It is RoHS3 compliant.
