This is a 15-position, single-row, right-angle SMT header from JST's PH series, pitched at 2.00 mm. It mates with the matching PH-series crimp receptacle housing to form a board-to-cable interconnect. For higher cycle life, the gold-plated sibling (S15B-PH-SM4-TB(LF)(SN)) is the better pick.
Mates with any JST PH-series crimp receptacle housing that has 15 circuits and 2.00 mm pitch. The crimp terminals are SPH-002T-P0.5S (tin) or SPH-004T-P0.5S (gold).
