This is a signal connector, not a power interconnect; each contact carries logic-level or low-current analog signals. ## Shielded Shell and IDC Termination The steel, tin-nickel plated shell is the EMI barrier — it mates with the receptacle shell to create a continuous shield around the pin field. The IDC termination means the ribbon cable is mass-terminated in one press operation; there are no individual crimp contacts to replace. If a wire breaks in the harness, the entire connector is replaced, not repaired one contact at a time. The free-hanging mount lets the cable assembly float inside the chassis without a board-mounted header.","metaTitle":"TE Connectivity 5749111-4 AMPLIMITE .050 III","metaDescription":"TE Connectivity 5749111-4 AMPLIMITE .050 III D-sub plug, 50 positions, 1A, 30V, IDC ribbon termination, shielded steel shell.","metaKeywords":null},"attributes":{"series":"AMPLIMITE .050 III","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["D-Sub & D-Shaped Connectors","D-Sub Cable Assemblies"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Color":"Black","Series":"AMPLIMITE .050 III","Package":"Tube","Features":"Shielded","Wire Gauge":"-","Termination":"IDC, Ribbon Cable","Contact Form":"-","Contact Type":"Signal","Mounting Type":"Free Hanging (In-Line)","Connector Type":"Plug, Male Pins","Contact Finish":"Gold","Flange Feature":"-","Number of Rows":"2","Product Status":"Active","Voltage Rating":"30V","Backset Spacing":"-","Connector Style":"D-Type","lifecycle_stage":"unknown","Contact Material":"Phosphor Bronze","Ingress Protection":"-","Base Product Number":"5749111","Dielectric Material":"Thermoplastic","Number of Positions":"50","Current Rating (Amps)":"1A","Operating Temperature":"-55°C ~ 105°C","Shell Material, Finish":"Steel, Tin-Nickel Plated","Contact Finish Thickness":"-","Material Flammability Rating":"UL94 V-0","Shell Size, Connector Layout":"0.050 Pitch x 0.100 Row to Row"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$12.7900","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$12.79000","currency":"USD"},{"qty":10,"price":"$11.56700","currency":"USD"},{"qty":25,"price":"$11.26120","currency":"USD"},{"qty":50,"price":"$10.83280","currency":"USD"},{"qty":100,"price":"$10.03710","currency":"USD"},{"qty":250,"price":"$9.97592","currency":"USD"},{"qty":500,"price":"$9.60870","currency":"USD"},{"qty":1000,"price":"$8.56826","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/08f0023f72e483d9099abdd9b8409107.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy the TE Connectivity 5749111-4 and what is the lead time?","answer":"The 5749111-4 is an active-production part sourced through independent distribution."},{"question":"Is 5749111-4 compatible with a standard 50-pin female D-sub?","answer":"Yes, this is a D-sub plug with male pins that mates with any standard 50-position D-sub receptacle using the same 0.050 inch pitch x 0.100 inch row-to-row layout.
