Right-Angle USB-A with a Fifth Contact
The Amphenol 73725-0010BLF is a USB 2.0 Type-A receptacle from the 73725 series, with 5 contacts in a single-port, right-angle through-hole package. The fifth contact is a sensor pin — not a standard USB-A feature — used for presence detection, grounding, or a chassis bond, depending on the board design.
