Board-Mount Header for Wire-to-Board Power
The EM02B-LEXSS-TF: This male pin header carries tin-plated contacts on a copper alloy base, rated for 3A (22 AWG) at 300V.
SMT Retention and Board Fit
The 2.50mm pitch leaves enough board space for routing a low-voltage power trace between pads while keeping the footprint compact. Mates with the JST LEXR-02V-S receptacle housing, which accepts crimp terminals for 22 AWG wire.
2 vs 4 Positions: What the Circuit Count Decides
The EM02B-LEXSS-TF carries two circuits, while the EM04B-LEXSS-TF carries four at the same 0.098" pitch and 3A per-contact rating. The choice is purely positional — the board footprint scales linearly with circuit count, and the mating receptacle (LEXR-02V-S for the 2-position, LEXR-04V-S for the 4-position) changes accordingly. No difference in current headroom, contact finish, or housing material between the two.
