The tin-on-tin contact finish (mating and post) is cost-effective for applications that don't demand high mating-cycle counts; expect several dozen cycles before wear becomes a concern.","metaTitle":"BM04B-ZESS-TBT JST Header SMD 4 Pos 1.5mm Pitch","metaDescription":"JST ZE series SMT header, 4 circuits, 1.50mm pitch, locking ramp, 2A, 100V.
