What this 8 mm pitch header does for the board layout
The SM02(8.0)B-BHS-1-TB is a 2-position, single-row header from JST's BH series, pitched at 0.315" (8.00 mm) — that's a wide spacing for a 2-position part, so the board footprint is roomy and the routing between pins is straightforward, even for a 600 V rated trace.
The 600 V rating is high relative to the current, so this header is suited for signal-level switching or control circuits where isolation matters more than power throughput, not for high-current power distribution.
How this header mates and terminates
This is a male pin header that mates with the BH series receptacle (female housing with crimp terminals).
