A detent lock on the housing side gives a tactile click when fully mated, reducing the chance of partial engagement.
Mating half and termination details
The B5B-PH-K-S mates with JST PH series crimp housings (e.g., PHR-5) loaded with the matching SPH-002T-P0.5S or SPH-004T-P0.5S crimp terminals. The detent lock on the header engages the latch on the housing for a positive hold. Termination is press-fit solder — the through-hole posts are designed for wave or hand soldering. The contact length on the post side is 0.134" (3.40 mm), which fits standard 1.6 mm PCBs with enough tail protrusion for a reliable solder fillet.
