USB Type A connector boasts over 20,000 mating cycles

When designing equipment with USB Type A connections, engineers often take for granted how many times they are mated and unmated in its lifetime. For some, this is not a concern as most are tested to 5,000 mating cycles, more than enough for its intended application. For others, this could mean the difference of a product failing far earlier than expected.
GCT has seen an increasing demand for USB Type A connectors with ultra-high mating cycles, primarily for equipment and hardware in public environments and transportation applications for charging purposes. Increased usage is likely due to exposure to high levels of footfall. A key measurement for establishing USB Type A mating cycles is based on retention force. Industry standard tests state the connector must have a final retention force of =>8N after cycling. The USB1086 maintains this force rating over 20,000 cycles due to its stainless steel shell construction. USB Type A connectors typically have a nickel-plated brass shell, resulting in tabs losing retention due to its low elasticity properties. This is not a problem for the USB1086 as it uses a high strength stainless steel material shell for enhanced tab elasticity. The USB1086 exceeds the standard mating cycles of newer USB types too, including USB Type C which is usually tested to 10,000 cycles.
