The B9B-PH-K-S(LF)(SN) is a 9-position, single-row, through-hole header from JST's PH series. It mates with JST PH series crimp housings (like the PHR-9) to form a wire-to-board connection.
Tin on the mating face suits moderate mating cycles (20–30 cycles) in a controlled environment. Mated stacking height is 8 mm, which fits standard board-to-cable spacing in compact enclosures.
Comparing the 9-Position to Its 8- and 10-Position Siblings
The B9B-PH-K-S(LF)(SN) sits between the B8B-PH-K-S(LF)(SN) (8 positions) and the B10B-PH-K-S(LF)(SN) (10 positions) in the same PH series. The 8- and 10-position versions are not pin-compatible substitutes — the board footprint and mating housing change with position count.
