The 0.059\" (1.50 mm) pitch keeps the board footprint tight — each position lands on 1.50 mm centers, which is the dimension that governs the PCB layout when mating with the matching pin header. Tin-plated female socket contacts handle the signal path; the closed-end housing prevents wire from pushing through the back of the connector during assembly, a detail that saves rework time on the harness bench. ## Termination and Wire Preparation Cable termination is IDC — insulation displacement, no crimp tool for individual contacts. The wire gauge is locked to 30 AWG; the IDC slot geometry is sized for that diameter, so substituting a different gauge risks an open or intermittent connection. Free-hanging (in-line) mounting means this receptacle sits in the harness, not on the board — it mates with a through-hole or SMT pin header on the PCB. The closed-end feature acts as a wire stop, so the assembler gets positive feedback when the conductor is fully seated.","metaTitle":"JST 12ZR-3H-P ZR Series IDC Receptacle, 12 Pos, 1.50 mm","metaDescription":"JST 12ZR-3H-P ZR series IDC receptacle, 12 positions, 0.059\" (1.50 mm) pitch, 30 AWG, tin-plated female sockets, free-hanging, closed end.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circular Connectors"],"specifications":{"Mfr":"JST Sales America Inc.","Color":"Natural","Pitch":"0.059\\\" (1.50mm)","Series":"ZR","Package":"Bulk","Features":"Closed End","Wire Type":"Discrete","Wire Gauge":"30 AWG","Row Spacing":"-","Contact Type":"Female Socket","Mounting Type":"Free Hanging (In-Line)","Connector Type":"Receptacle","Contact Finish":"Tin","Fastening Type":"-","Number of Rows":"1","Product Status":"Active","lifecycle_stage":"unknown","Cable Termination":"IDC","Base Product Number":"12ZR","Number of Positions":"12","Contact Finish Thickness":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3984","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/da6b36aae3004270c02401e4d75d4a0e.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/12ZR-3H-P/alternatives.json"},"ai":{"faq":[{"question":"What is the pitch of the 12ZR-3H-P?","answer":"The 12ZR-3H-P has a 0.059\" (1.50 mm) pitch — the center-to-center spacing between adjacent positions.
