What this 2-position XH header does
Pitch, positions, and board footprint
At 2 positions and 2.50 mm pitch, this header occupies minimal board real estate — a single-row footprint that routes easily on 1- or 2-layer PCBs. The through-hole termination with press-fit solder tails (0.134" post length) anchors the connector during wave soldering and resists shear force from the mated cable assembly. Compared to the 7-position sibling BH7B-XH-2, the BH2B-XH-2 covers only the simplest power or signal pair — useful for a single sensor, switch, or LED connection where a larger header would waste board space. The closest functional second-source is BH2B-XH-2(LF)(SN) — identical pinout, pitch, and ratings, with the same natural PA66 housing. The (LF)(SN) suffix indicates lead-free and tin-plated contacts; the base BH2B-XH-2 is RoHS non-compliant per, so verify your assembly's RoHS requirement before substituting.
Current, voltage, and thermal limits
The UL94 V-0 rated PA66 housing supports use in equipment requiring flame-retardant materials inside an enclosure, such as power supplies or control modules.
The base product number BH2B-XH covers both the standard and lead-free variants. For RoHS-compliant builds, order BH2B-XH-2(LF)(SN) instead.
