The ST40X-18S-CV(80) is a 18-position 1-row female Interface Plug with gold plated brass contacts and glass filled polyacetal resin insulator. The ST series connector has chrome plated brass/zinc alloy shell and straight connector orientation. Specifically designed for use as input/output (I/O) connectors on portable information devices. They feature a unique structure with high strength which resists deformation and helps to prevent improper mating. 3.0mm height and 0.5mm contact pitch connector prevents EMI as well. To assure continuous reliability of the connection in an unpredictable consumer environment, mated connectors will withstand pull force of 49N maximum applied in any direction. Multiple polarization keys will not allow incorrect insertion of the mating plug. In addition, contacts will not be damaged when the user attempts to insert only the corner of the mating plug.
