Contact system and reconnect duty
The 124018792112A: The 5 A per-contact rating and gold plating suit repeated reconnect duty in field-service or test-bench applications where contact fretting from frequent insertion is a concern.
Sealing and signal rating
IP68 dust-tight and waterproof rating covers the mated interface when the mounting flange is seated against the panel gasket — the seal holds under washdown or outdoor exposure. USB 3.2 Gen 2 (10 Gbps) data-rate capability supports SuperSpeed+ signalling through the single-port receptacle.
