Contact system and board lock
The USB-A-S-F-W-TH is a 4-contact USB 2.0 Type-A receptacle from Samtec's USB-A series, rated for 1500 mating cycles with gold-plated contacts. Board locks on the through-hole right-angle mount hold the connector during reflow and resist shear from cable strain.
Within the USB-A series the USB-A-S-F-W-TH's 4 contacts match the standard Type-A pinout — the same count as the surface-mount USB-A-S-F-W-SM2, but the through-hole right-angle termination and board lock differ from the SM2's board guide and solder retention.
