Rated 1 A per contact at 50 V, the header uses tin-plated mating contacts and terminates via through-hole solder posts. ## Shrouded housing with detent lock A four-wall shrouded housing protects the male pins and includes a detent lock for secure mating with the ZH receptacle. The single-row layout keeps the board footprint narrow, suited for dense wiring harnesses. ## Active production status JST Sales America Inc. lists the S12B-ZR(LF)(SN) as Active — quoted to order against BOM quantities.","metaTitle":"JST ZH S12B-ZR(LF)(SN) Header, 12-Pos 1.50mm","metaDescription":"JST ZH header S12B-ZR(LF)(SN): 12 positions, single row, 1.50 mm pitch, 1 A, 50 V, tin-plated contacts, through-hole right-angle, shrouded.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Mfr":"JST Sales America Inc.","Style":"Board to Cable/Wire","Series":"ZH","Package":"Bulk","Features":"-","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","Applications":"-","Contact Type":"Male Pin","Contact Shape":"Circular","Mounting Type":"Through Hole, Right Angle","Connector Type":"Header","Fastening Type":"Detent Lock","Number of Rows":"1","Pitch - Mating":"0.059\\\" (1.50mm)","Product Status":"Active","Voltage Rating":"50V","lifecycle_stage":"unknown","Contact Material":"Brass","Insulation Color":"Natural","Insulation Height":"0.146\\\" (3.70mm)","Ingress Protection":"-","Base Product Number":"S12B-ZR","Insulation Material":"Polyamide (PA66), Nylon 6/6, Glass Filled","Number of Positions":"12","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"0.106\\\" (2.69mm)","Current Rating (Amps)":"1A","Operating Temperature":"-25°C~85°C","Mated Stacking Heights":"-","Overall Contact Length":"-","Contact Finish - Mating":"Tin","Contact Length - Mating":"0.094\\\" (2.40mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"-","Contact Finish Thickness - Mating":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5500","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/2fb95b8ede28dbfc6d8876369fc84cb5.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the mating half for this header?","answer":"The S12B-ZR(LF)(SN) mates with the ZH series receptacle housing (e.g., ZR-12) using crimp terminals.
