The 2MM-HB-S10-VT-02-H-TB: The 10-position single-row layout keeps the board edge narrow, useful for tight channel spacing in a multi-connector panel. Unshrouded breakaway design means the header can be snapped to length for non-standard circuit counts, though this part ships with all 10 positions loaded.
In a field-service application where the connector is cycled quarterly, that is over a century of service life at the contact interface. The post finish is 12 µinch tin, standard for solder-joint reliability.
