It's built to the USB 2.0 specification — four contacts for the standard USB signal pair plus power and ground, with a fifth ID pin for On-The-Go host negotiation.
Why the 10000-Cycle Rating Matters for Field Service
Standard micro-B connectors are good for maybe 5000 cycles before the gold plating on the receptacle fingers starts to wear through and the contact resistance drifts. At 10000 cycles, this plug's gold finish is thick enough to survive twice that many matings — relevant if the cable is the daily connection for a field programmer or a diagnostic tool that gets plugged into a dozen units a shift. The steel and stainless shell/shielding material adds mechanical robustness; the stainless variant resists corrosion from hand oils and mild industrial atmosphere better than a plain nickel shell.
If the design can tolerate a current-production USB micro-B plug from the same family, the pinout and footprint are standardised by the USB-IF, so a cross-check against an active TE or equivalent part is worth the time before committing to a last-time buy.
Solder-termination plug — the five contacts are soldered to the cable conductors. Free-hanging (in-line) mount terminates the cable end.
