Connector Overview and Key Specs
The Hirose ST40X-10S-CV(30) is a 10-position, single-row shielded plug from the ST series, designed for discrete wire termination. The free-hanging (in-line) mount and solder termination make it a field-serviceable option for harnesses where a PCB header isn't present.
Shielding and Application Fit
The 'Shielded' feature is the defining characteristic of this variant. The metal shell around the contact area provides a continuous ground path when mated with a shielded receptacle, reducing radiated emissions and improving immunity to external interference. This makes the ST40X-10S-CV(30) a natural fit for signal interconnects inside enclosures with EMI requirements—think industrial controllers, test equipment, or medical peripherals where a clean signal path matters more than raw current capacity.
The solder termination requires a soldering iron or reflow station for each wire—no crimp tool needed, but each joint is permanent. The free-hanging mount means it floats in the cable harness, so strain relief at the cable exit is the installer's responsibility. The 1-row layout keeps the assembly narrow, useful for tight cable bundles.
