Release of a “Micro USB Connector (Strong type)” with our unique structure ensuring increased resistance to twisting force

We are pleased to announce we have developed and released a Micro USB (Strong type) interface connector.
This product features our unique dual shield case structure to deal with connector strength problems due to the miniaturization of connectors in recent years. This structure strengthens twisting force deformation resistance by approximately twice more than our existing products, contributing to increased reliability.
The dual shield case structure not only provides a relief structure between its external and internal sides and features a structure to prevent vertical and horizontal displacement. Further, this product features a flux prevention mechanism inside the plug insertion hole which removes the need for internal internal notches and holes by placing the mounting foot in the external shield case.
To respond to needs for the increased compactness and thinness of equipment, we have developed a low-profile product with a mounting height of 2.80mm.
This product is compliant with USB standards (Revision 2.0).
