Vertical USB-A Receptacle for Panel-Mount and PCB Integration
The TE Connectivity 1734366-3 is a USB 2.0 Type-A receptacle with 4 contacts in a single port, designed for vertical through-hole mounting. The shielded brass shell and gold-plated contacts handle the USB 2.0 signal pair and power lines, rated at 1A per contact at 30VAC. The blue insulation color is a standard identifier for USB 3.0 backward-compatible receptacles, though this part is specified for USB 2.0 operation.
Durability and Signal Integrity for Repeated Mating
Rated for 1500 mating cycles, the gold contact finish on both plug and receptacle surfaces prevents fretting corrosion and maintains contact resistance below the USB 2.0 specification threshold over the life of the port. The shielded shell with brass construction provides EMI containment from 30 MHz to several GHz, keeping radiated emissions within FCC Class B limits for digital devices. The 30VAC rating is typical for USB power delivery; the 1A per contact limit means the connector can supply standard 5V at 1A without exceeding the temperature rise budget of the housing.
