It carries 5 contacts in a single port, with a shielded shell of steel and stainless steel to contain EMI in data and power applications. The gold-plated contacts handle a dual current rating of 1A and 1.8A at 30VAC — the higher figure typically assigned to the dedicated power pin for charging duty. This is the AB variant, meaning it accepts both micro USB A and micro USB B plugs, making it a universal host-side connector for devices that need to support both cable types.
Mating Cycles and Field Reliability
That figure tells you the contact plating and spring-beam design are specced for frequent plug/unplug duty in field-service equipment, test fixtures, or portable instruments where the connector sees daily use.
