It mates with the 6ES7392-1AM00-0AA0 connector on the module face and brings the field wiring out on a 3.2 m cable bundle — saves you having to hand-wire each terminal at the rack. Rated at 24 V nominal (30 V maximum), it handles the standard S7-300 24 VDC field supply for digital inputs and outputs. The 40 cores match the full channel count of a 40-pin I/O module — no spare pins left unterminated. ## Wiring and field connection details Each core is 0.5 mm² H05V-K, individually numbered 1 to 40 with a white adapter marking, so tracing a field device back to its channel is straightforward during commissioning. The cable sheath is blue PVC, 2.2 mm outer diameter per core, bundled. Termination on the module side is screw-type — no special tool needed beyond a standard screwdriver. The connector housing itself uses a screw terminal on the enclosure side as well. Storage temperature range is -30 to +70 °C; operating range is 0 to 60 °C. The cable is rated for digital signal transmission only — not for analog signals. Mature lifecycle — still specified into new S7-300 builds and supported for existing installations. Supplied in a VPE of 5 units per package.","metaTitle":"Siemens 6ES7922-3BD20-5AC0 Front Connector, 40-Pole","metaDescription":"Siemens 6ES7922-3BD20-5AC0 front connector with 40 single cores (0.5 mm²) for SIMATIC S7-300 digital I/O modules. 3.2 m cable, screw terminals.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["PLC Accessories"],"specifications":{"title":"6ES7922-3BD20-5AC0","Maximum":"30 V","Rated Value":"24 V","Wire Length":"3.2 m","description":"Front connector for SIMATIC S7-300 40 pole (6ES7392-1AM00-0AA0) with 40 single cores 0.5 mm2, Single cores H05V-K, Screw version VPE=5 units L = 3.2 m","In The Field":"other","On Enclosure":"Screw-type terminal","Target System":"SIMATIC S7-300","Connector Type":"6ES7392-1AM00-0AA0","During Storage":"-30 ... +70 °C","input card PLC":"Yes","Design Of Cable":"H05V-K","Number Of Poles":"40; of the front connector","PLC output card":"Yes","lifecycle_stage":"mature","During Operation":"0 ... 60 °C","RAL color number":"RAL 5010","Marking / Of Cores":"Number consecutively from 1 to 40 in white adapter contact = core number","Number Of Channels":"40","Product Designation":"Front connector with single cores","Suitability For Use":"Digital I/O modules","Color / Of Cable Sheath":"blue","Analog Signal Transmission":"No","Digital Signal Transmission":"Yes","Type Of Connecting Terminal":"Screw-type terminal","Outer Diameter / Of Cable Sheath":"2.2 mm; bundled single cores","Conductor Cross Section / Rated Value":"0.5 mm²","Material / Of The Connection Cable Sheath":"PVC","reference code / according to IEC 81346-2":"WG"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$991.00","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/6d57f154fff616166253fab8c566f5cb.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=137288&mlfb=6ES7922-3BD20-5AC0"},"ai":{"faq":[{"question":"How can I order the 6ES7922-3BD20-5AC0 or check stock?","answer":"Submit a request with your quantity and target delivery window."},{"question":"What is the cable length and conductor size?","answer":"The cable is 3.2 m long with 40 single cores of 0.5 mm² cross-section, H05V-K type, individually numbered."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/6ES7922-3BD20-5AC0","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/6ES7922-3BD20-5AC0 when reusing this data.
