The Hirose ST series was developed as external input / output connectors for the portable and mobile devices used in the consumer markets. Featuring a low profile, the connector is only 3.0 mm above the mounting surface. To assure continued reliability of the connection, mated connectors will withstand a pull force of 49 N max applied in any direction. Multiple polarization keys will not allow incorrect insertion of the mating plug. Contacts will not be damaged when the user attempts to insert only the corner of the mating plug.
