1.27mm Pitch, 50 Circuits, 6.42mm Stack Height — the Mezzanine Fit
The 87409-125CTLF: Rated 1A DC per circuit. At 50 circuits that is 50A total across the connector, but the practical limit per signal is the 1A ceiling — fine for logic-level signals, low-power sensor buses, or control lines.
Shrouded 4-Wall, Push-Pull, SMT — Board Assembly and Retention
Surface-mount termination with board guide and pick-and-place features means it is designed for automated assembly: the board guide aligns the part to the PCB pads, and the pick-and-place pad lets the nozzle handle it without disturbing the pins.
