What this 2-pin SMT header does in a board-to-wire link
Footprint and assembly: SMT with solder retention
Surface-mount termination with integrated solder retention tabs holds the header steady during reflow, reducing the risk of skew or tombstoning on the pick-and-place line. The mated stack height of 8.6mm gives the board layout engineer a clear z-axis constraint for enclosure clearance. Insulation height is 0.260" (6.60mm) above the PCB, and the contact mating length is 0.130" (3.30mm) — enough for a reliable wipe with the receptacle's female contacts.
RoHS compliance is standard for the PH series; no separate certification document is listed, but the material declaration supports it.
Mating half and peer comparison: picking the right position count
The mating connector is a PH-series crimp receptacle housing with 2.00mm pitch female terminals — order the housing and terminals separately for a complete wire-to-board assembly. Within the same SM4-TB family, the B3B-PH-SM4-TB (3 positions), B5B-PH-SM4-TB (5 positions), and B6B-PH-SM4-TB (6 positions) share identical pitch, current rating, and SMT footprint — only the position count changes, so a 2-position BOM can be scaled up by swapping to a higher-count sibling without requalifying the footprint.
