The closed-end housing prevents the wire from pushing past the insulation displacement slot, ensuring consistent termination depth every cycle. The orange colour of the housing is standard for this position count in the MTA-156 family, aiding visual identification on the assembly line or during field service. ## Termination and Tooling IDC termination for 18 AWG discrete wire requires a dedicated hand tool or bench press with the appropriate MTA-156 die set — the connector does not accept a generic crimp tool. The closed-end feature guides the wire into the slot and prevents over-insertion, but the insulation must be stripped to the correct length for the IDC tines to bite through and make contact with the conductor. ## Contact Finish and Durability","metaTitle":"TE MTA-156 3-640426-6, 6-Pos IDC Receptacle, 0.156\" Pitch","metaDescription":"TE Connectivity MTA-156 3-640426-6, 6-position IDC receptacle for 18 AWG discrete wire, tin contacts with 80.0µin plating, locking ramp, closed end, RoHS","metaKeywords":null},"attributes":{"series":"MTA-156","packageCase":null,"mountingType":null,"rohsStatus":"RoHS Compliant","productStatus":"Active","categoryPath":["Circular Connectors","Panel-Mount & In-Line Circular"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Color":"Orange","Pitch":"0.156\\\" (3.96mm)","Series":"MTA-156","Package":"Bulk","Features":"Closed End","Wire Type":"Discrete","Wire Gauge":"18 AWG","Row Spacing":"-","Contact Type":"Female Socket","Mounting Type":"Free Hanging (In-Line)","Connector Type":"Receptacle","Contact Finish":"Tin","Fastening Type":"Locking Ramp","Number of Rows":"1","Product Status":"Active","lifecycle_stage":"unknown","Cable Termination":"IDC","Base Product Number":"640426","Number of Positions":"6","Contact Finish Thickness":"80.0µin (2.03µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6700","priceTiers":[{"qty":1,"price":"$0.67000","currency":"USD"},{"qty":10,"price":"$0.65200","currency":"USD"},{"qty":25,"price":"$0.64960","currency":"USD"},{"qty":50,"price":"$0.62780","currency":"USD"},{"qty":100,"price":"$0.52640","currency":"USD"},{"qty":250,"price":"$0.49348","currency":"USD"},{"qty":500,"price":"$0.46606","currency":"USD"},{"qty":1000,"price":"$0.40849","currency":"USD"},{"qty":2500,"price":"$0.38656","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/3-640426-6/alternatives.json"},"ai":{"faq":[{"question":"What is the pitch and wire gauge of 3-640426-6?","answer":"The 3-640426-6 has a 0.156\" (3.96mm) pitch and is designed for 18 AWG discrete wire. The pitch matches the MTA-156 header footprint; the wire gauge is fixed by the IDC slot geometry — no other AWG fits without a different connector variant."},{"question":"Does 3-640426-6 come with a closed end and locking ramp?","answer":"Yes. The housing features both a closed end — which stops the wire from pushing past the IDC slot — and a locking ramp that snaps onto the mating header for vibration-resistant retention."},{"question":"Where can I buy 3-640426-6?","answer":"This part is sourced and quoted to order against your BOM quantity.
