The 10129380-910001ALF: The connector is cuttable, meaning a single BOM line can serve multiple position counts by snapping the strip to length — useful for low-volume builds where inventory flexibility matters. Surface mount termination (SMT) allows reflow soldering, which reduces assembly labor and improves joint consistency compared to through-hole.
For higher cycle counts, consider a thicker gold option in the same series.
The voltage rating is 110 VDC, which is typical for signal-level circuits in general-purpose and medical applications. Current is limited to 3 A per contact; derate above 105°C ambient per the standard derating curve.
