The closed-end back wall stops the wire at a positive depth — no risk of pushing the conductor through the back during assembly. The 0.156\" (3.96mm) pitch matches the standard MTA-156 header footprint. At 6 circuits, this is a mid-range position count in the series — common for power or signal distribution in appliances, HVAC controls, and lighting ballasts where the wire gauge and pitch align with the current draw. ## IDC Termination and Wire Prep The 3-640427-6 is specced for 20 AWG wire; using a different gauge risks an unreliable gas-tight joint. The closed-end feature is a practical detail: it gives a positive stop for the wire, so the assembler knows the conductor is fully seated without a visual check through the back. This thickness ensures the slot bites through the oxide layer on the wire and maintains a stable connection over temperature cycles. It is not a high-mating-cycle finish; the IDC joint is essentially a one-time termination. ## Locking Ramp and Harness Retention It is a single-action latch: push to mate, lift the ramp to release.","metaTitle":"TE MTA-156 3-640427-6, 6-Pos IDC Receptacle, 0.156\" Pitch","metaDescription":"TE 3-640427-6 MTA-156 receptacle, 6 positions, 0.156\" (3.96mm) pitch, IDC termination for 20 AWG discrete or ribbon cable.","metaKeywords":null},"attributes":{"series":"MTA-156","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Circular Connectors","Panel-Mount & In-Line Circular"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Color":"Yellow","Pitch":"0.156\\\" (3.96mm)","Series":"MTA-156","Package":"Bulk","Features":"Closed End","Wire Type":"Discrete or Ribbon Cable","Wire Gauge":"20 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":"640427","Number of Positions":"6","Contact Finish Thickness":"80.0µin (2.03µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.7000","priceTiers":[{"qty":1,"price":"$0.70000","currency":"USD"},{"qty":10,"price":"$0.67900","currency":"USD"},{"qty":25,"price":"$0.67640","currency":"USD"},{"qty":50,"price":"$0.65360","currency":"USD"},{"qty":100,"price":"$0.54790","currency":"USD"},{"qty":250,"price":"$0.51368","currency":"USD"},{"qty":500,"price":"$0.48516","currency":"USD"},{"qty":1000,"price":"$0.42522","currency":"USD"},{"qty":2500,"price":"$0.40239","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/3-640427-6/alternatives.json"},"ai":{"faq":[{"question":"What wire gauge does 3-640427-6 support?","answer":"The 3-640427-6 is designed for 20 AWG wire, either discrete or ribbon cable.
