Right-angle 2.50mm pitch header for tight board-to-cable routing
The S2B-XH-A: Its right-angle through-hole mounting and shrouded 4-wall design mean the header sits flush against the PCB edge, and the mating receptacle is guided into position without risk of bending pins. The detent lock gives a positive click when the cable-side housing engages, so you know the connection is fully seated — no guessing, no partial mates that later vibrate loose.
The closest functional peer is the S3B-XH-A-1, which shares the same 2.50mm pitch, right-angle orientation, shrouded 4-wall, detent lock, and 3 A / 250 V rating — the only difference is 3 positions vs 2.
