USB-A Receptacle, 4 Contacts, Right-Angle Board Lock
It sits in the 73725 series as a single-port, right-angle, through-hole mounted jack with a vertical mounting feature — the connector body stands perpendicular to the PCB edge, not parallel.
1500 Mating Cycles — GXT Gold Plating
The contact finish is Gold, GXT™ — Amphenol's enhanced gold-over-nickel plating system. This is what delivers the 1500 mating cycles rating, well above the 500-cycle baseline for standard tin-plated USB jacks. For a port that sees frequent reconnection — test equipment, kiosk peripherals, field-service laptops — that cycle life translates to fewer field failures from contact wear. The GXT plating also resists corrosion in environments where condensation or mild industrial fumes are present.
Shielded Shell, UL 94 V-0 Housing
The shell is Copper Alloy, fully shielded — the metal shroud wraps the contact area and grounds through the solder tabs to the PCB ground plane, containing radiated emissions from the USB 2.0 differential pair. Insulation color is black.
