The 2134758-1: The right-angle, surface-mount orientation places the plug at the board edge, keeping the battery cable entry parallel to the PCB plane for a low-profile harness layout.
Termination is solder-only — no crimp or press-fit option — with the SMT pads held in place during reflow by the solder retention feature built into the housing. The board-edge mount with right-angle orientation means the plug body overhangs the PCB edge, so the board layout needs a cutout or edge clearance for the connector body. The push-pull fastening type gives a simple mate/unmate cycle without a locking latch, suited for battery connections where the user disconnects the pack manually.
The housing is molded from black thermoplastic, and the contacts are copper alloy with a gold finish. The part is ROHS3 compliant, which covers the current EU restricted-substance directive. The base product number is 2134758, and the full order code 2134758-1 is the specific variant with the offset blade arrangement noted in the manufacturer description.
