Product details

0.35mm Pitch Mezzanine Header for Tight Stack Heights

The Hirose BM29B-24DP/2-0.35V(53) is a 26-position header from the BM29 series, configured as 24 signal contacts plus 2 dedicated power contacts in a dual-row layout. It's designed for board-to-board mezzanine stacking with a mated height of 0.6mm, placing it in the ultra-low-profile category for thin handheld or wearable electronics. The 0.014" (0.35mm) pitch demands careful PCB routing — expect fine trace widths and via-in-pad techniques to keep the signal paths clean.
