It uses a 0.016\" (0.40mm) pitch across two rows, and when mated with the matching receptacle the stack height lands at 0.8mm — one of the lower profiles in the series. The connector type is listed as Header, Outer Shroud Contacts, meaning the signal pins sit inside a shroud that protects them during handling and misalignment before full engagement. This header is surface-mount only, with no through-hole option in the BM10 family. The 0.63mm height above board after soldering keeps the assembly thin, which matters when the second board sits directly above with only 0.8mm of clearance. ## 10 positions vs 16, 24, 30 — same footprint, different circuit count The BM10 series shares the same 0.40mm pitch, 0.8mm stack height, and gold plating across all position counts. The BM10B(0.8)-10DP-0.4V(51) at 10 positions is the smallest in the group; the 16-position BM10B(0.8)-16DP-0.4V(51) and the 24- and 30-position siblings use the same footprint width but add contacts along the row. No difference in plating thickness or solder retention features across the range. RoHS compliant per the listing.","metaTitle":"Hirose BM10B(0.8)-10DP-0.4V(51), 10pos 0.4mm pitch Header","metaDescription":"Hirose BM10 series header, 10 positions, 0.40mm pitch, 0.8mm stack height.
