Its interlock function (latching safety circuit) together with 2 NC contacts that open on simultaneous latching means the machine cannot restart until the pedal is physically reset — a key requirement for safeguarding per IEC 61496-1. Rated 16 A at 400 V and 3 A at 24 V, this foot switch handles both high-voltage motor control circuits and low-voltage PLC inputs from the same contact block. ## Sourcing and lifecycle — active production, no obsolescence risk The metal enclosure and M20 x 1.5 cable entry match standard panel gland plates; the 2 NO + 2 NC auxiliary contact arrangement gives you both a safety channel and a status feedback channel without adding a separate relay. ## Integration checklist — panel wiring and ambient limits Operating temperature range -25 to +80 °C covers both cold storage and hot machine-side mounting without derating. Minimum actuation force of 240 N prevents false triggers from vibration or incidental contact — the pedal requires deliberate foot pressure to close the NO contacts.","metaTitle":"Siemens 3SE2924-3AA20 Safety Foot Switch, IP65, 2NO+2NC","metaDescription":"Siemens 3SE2924-3AA20 SIRIUS safety foot switch, 1-pedal with interlock, IP65 metal enclosure, 2 NO + 2 NC contacts, rated 16 A at 400 V.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Limit Switches"],"specifications":{"Depth":"265 mm","Width":"156 mm","title":"3SE2924-3AA20","Height":"138 mm","Latching":"No","Interlock":"Yes","description":"safety foot switch 1-pedal, with protective cover, IP65, with interlock function, 2 NO+2 NC, NO contact, closes as pushbutton, NC contact, opens with simultaneous latching (safety function), cable entry M20 x 1.5","lifecycle_stage":"current","Cable Entry Type":"M20 x 1.5","Of The Enclosure":"black","Product Brand Name":"SIRIUS","Product Designation":"safety foot switch","at 24 V rated value":"3 A","protection class IP":"IP65","at 230 V rated value":"16 A","at 250 V rated value":"0.25 A","at 400 V rated value":"16 A","Material Of The Enclosure":"metal","Number Of Switching Steps":"2","Of The Enclosure Top Part":"grey","Substance Prohibitance (Date)":"07/01/2006","Number Of The Actuation Pedals":"1","Suitability For Use Safety Switch":"Yes","Ambient Temperature During Operation":"-25 ... +80 °C","reference code according to IEC 81346-2":"S","with low demand rate according to SN 31920":"50 %","with high demand rate according to SN 31920":"50 %","number of NC contacts for auxiliary contacts":"2","number of NO contacts for auxiliary contacts":"2","Minimum Actuating Force In Directions Of Actuation":"240 N"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$152.40","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/73843b6bef380ea62ac7897a3e97026b.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=448148&mlfb=3SE2924-3AA20"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3SE2924-3AA20","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/3SE2924-3AA20 when reusing this data.
