ZH series, B4B-ZR, Board to Cable/Wire, Header, Male Pin, 4 Positions, 1.50mm Pitch, Through Hole, Solder, Detent Lock, 1A, 50V","salesMarkdown":"It mates with the ZH series crimp housing and the appropriate crimp terminal to form a complete wire-to-board interconnect. ## Pitch, footprint, and stack height for board layout The 1.50 mm pitch (0.059 in) is the narrowest in the ZH series, so the through-hole footprint demands careful trace routing between adjacent pins. The contact length on the mating side is 0.094 in (2.40 mm), and the post length is 0.106 in (2.69 mm). ## Shrouding and locking for field reliability The detent lock engages with the mating housing latch, providing a positive tactile click that confirms full insertion.","metaTitle":"B4B-ZR JST ZH Header 4-Pin 1.5mm Pitch Through Hole","metaDescription":"JST ZH series B4B-ZR header, 4 positions, 1.50mm pitch, shrouded, 1A, 50V, detent lock.
