ZH series, Board to Cable/Wire, 5 Positions, 1.50mm Pitch, Surface Mount, Shrouded - 4 Wall, Detent Lock, Tin Contacts, 1A/50V, UL94 V-0","salesMarkdown":"The B5B-ZR-SM4-TF is a 5-position, single-row SMT header from JST's ZH series, pitched at 1.50 mm. It's a shrouded 4-wall header, which means the receptacle self-aligns during mating and the pins stay protected from accidental bending — a real help when you're assembling a harness blind in a tight enclosure. At this pitch and contact size, the 1 A limit is driven by the temperature rise of the PA6T housing — push past it and the plastic creeps, losing contact force. The 50 V rating is conservative for signal-level work; it's the clearance between adjacent pins that sets the ceiling, not the insulation.","metaTitle":"B5B-ZR-SM4-TF JST ZH Header, 5 Pos, 1.5mm Pitch, SMT","metaDescription":"JST ZH series 5-position SMT header, 1.50mm pitch, shrouded 4-wall, rated 1A/50V.
