Its defining dimension is the 0.6mm mated stacking height — the shortest in the BM20 family — which makes it the go-to choice when the Z-axis budget between parallel PCBs is under a millimeter. Gold-plated contacts with 2.00µin (0.051µm) thickness handle repeated mating cycles in field-serviceable assemblies. ## Solder Retention Keeps It Put Through Reflow This receptacle includes solder retention features — integral metal tabs on the body that reflow-solder to pads on the PCB. In a 0.6mm stack height design, there's no room for through-hole board locks, so these surface-mount retention anchors take the shear load from cable strain or vibration during the product's life. The 2-row, 10-contact layout gives a balanced footprint that resists tombstoning during reflow. ## Mates with BM20 Series Headers — Same Pitch, Same Series The BM20B(0.6)-10DS-0.4V(53) mates with the matching BM20 series header that shares the same 0.016\" (0.40mm) pitch and 2-row layout. The \"(0.6)\" in the order code specifies the header's mated stacking height — so this receptacle pairs with a 0.6mm-tall header to achieve the total 0.6mm stack. A 0.8mm header (like the BM20B(0.8)-10DS-0.4V(51)) will not mate to the same height; the header height must match the receptacle's designated stack. The center strip contact interface is designed for signal-level currents typical of mezzanine interconnects in portable electronics. ## Position Count vs. Sibling — 10 or 20 Positions at the Same Height For the same 0.6mm mated stacking height, the BM20 series offers a 20-position variant — the BM20B(0.6)-20DS-0.4V(53). Both share the 0.016\" (0.40mm) pitch, 2-row layout, gold contacts, and solder retention. The choice comes down to signal count: 10 positions for a narrower interconnect, 20 for denser routing. The 10-position body is physically shorter along the mating axis, which can simplify alignment in tight board stacks.","metaTitle":"Hirose BM20B(0.6)-10DS-0.4V(53) 10-Pos 0.40mm Receptacle","metaDescription":"Hirose BM20 series receptacle, 10 positions, 0.016\" (0.40mm) pitch, 0.6mm mated stacking height.
