It carries male pins on a 0.050-inch pitch with 0.100-inch row spacing — the standard.050 III layout for high-density signal interconnects. The 50-position count and 2-row density make this plug a fit for parallel data buses, industrial I/O, or any application where a shielded ribbon cable needs a reliable D-sub interface. ## Shielding and Termination — What the Specs Mean The shielded steel shell with tin-nickel plating is the key differentiator here. It bleeds EMI from the cable braid to the chassis ground before the signal reaches the pin field — critical for data lines running near motors, VFDs, or switch-mode supplies. The IDC termination means the ribbon cable is pressed onto the insulation-displacement contacts in one operation; no stripping, no soldering. This gives a consistent gas-tight connection across all 50 positions, but the cable must be the correct gauge and pitch for the IDC slot geometry — verify the ribbon cable spec against the connector's wire range before building the harness. In a field-service environment where the connector is unmated and re-mated during troubleshooting, the gold finish prevents fretting and signal dropout.","metaTitle":"TE AMPLIMITE .050 III 5749621-5, 50-Pos D-Sub Plug","metaDescription":"TE Connectivity AMPLIMITE .050 III 5749621-5 D-sub plug, 50 positions, 1A, 30V, shielded IDC termination, gold contacts, UL94 V-0.","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":"Bulk","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":"5749621","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":"$12.0400","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$12.04000","currency":"USD"},{"qty":10,"price":"$10.88900","currency":"USD"},{"qty":25,"price":"$10.60080","currency":"USD"},{"qty":50,"price":"$10.19760","currency":"USD"},{"qty":100,"price":"$9.44870","currency":"USD"},{"qty":250,"price":"$9.39104","currency":"USD"},{"qty":500,"price":"$9.04538","currency":"USD"},{"qty":1000,"price":"$8.06594","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/d692d5bcb2244c51e3d3b87eb9ab4e29.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the contact arrangement of 5749621-5?","answer":"It is a 50-position D-sub plug with male pins arranged in 2 rows.
