The holding brake and IP65 rating on the body mean the motor is sized for machines where the shaft has to hold position when the drive is de-energised and where the cabinet-side environment sees washdown or airborne oil. Two operating points are published on the rating plate: 0.6 kW at nN=6000 rpm on a 380-480 V supply, and 0.4 kW at nN=3000 rpm on a 200-240 V supply, with M0=1.27 Nm static torque. The 200-240 V point covers North American single-phase-fed drive cabinets, while the 380-480 V point is the European/Asian three-phase default. ## Mechanical and feedback package The shaft is D19x40 mm with a feather key, the encoder is an AS22DQC single-turn 22-bit absolute encoder, and the housing is sealed to IP65. For a packaging-machinery builder that means the feedback resolution is sufficient for index-and-orient stop routines without needing a battery-backed multi-turn module, and the brake release is wired through the same M17 power plug that carries the motor phases. This variant carries a holding brake as standard — the -1SB0 suffix is the brake option in the 1FK2 order-code structure — and is ordered in single-piece quantity per the Product Group 9021 / Group Code R220 cataloguing. Export classification is AL:N / ECCN:N_CNDU, which simplifies cross-border shipments. ## Lifecycle, ordering terms, and compliance For the documentation pack a procurement audit will ask for, the RoHS date and the REACH statement are the entries that travel with the shipment. The motor ships in single-piece pack at 452.00 x 250.00 x 267.00 mm — useful for crate planning on a panel-builder receiving dock.","metaTitle":"Siemens 1FK2104-4AK11-1SB0 servo motor, 0.6 kW, brake, IP65","metaDescription":"Siemens 1FK2104-4AK11-1SB0 SIMOTICS S-1FK2 HD servomotor, 0.6 kW at 6000 rpm, holding brake, IP65, DRIVE-CLiQ.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Servo Motors with Brake"],"specifications":{"title":"1FK2104-4AK11-1SB0","Group Code":"R220","description":"SIMOTICS S-1FK2 HD servo motor M0=1.27 Nm; PN = 0.6 kW at nN=6000 rpm (380-480 V); PN = 0.4 kW at nN=3000 rpm (200-240 V); with holding brake; degree of protection IP65; shaft D19x40 mm with feather key; absolute encoder single-turn 22-bit (encoder AS22DQC); with DRIVE-CLiQ plug M17; power connector size M17;","Product Group":"9021","Product class":"C: products manufactured / produced to order, which cannot be reused or re-utilized or be returned against credit.","Quantity Unit":"1 Piece","Product Family":"1FK2 servomotors for SINAMICS S120","lifecycle_stage":"current","Packaging Quantity":"1","Export Control Regulations":"AL : N / ECCN : N_CNDU","Packaging dimensions (L x W x H)":"452.00 x 250.00 x 267.00 mm","Compliance with the substance restrictions according to RoHS directive":"Since: 01-07-06","REACH Art. 33 Duty to inform according to the current list of candidates":"Reach Information"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/a2ee49c3fd360a73f47b09bb15764103.pdf","sourceUrl":"https://sieportal.siemens.com/en-ae/products-services/detail/1FK2104-4AK11-1SB0?tree=CatalogTree"},"ai":{"faq":[{"question":"How do I get current pricing and availability for 1FK2104-4AK11-1SB0?","answer":"Lead time and per-unit landed cost are not carried as fixed numbers on a listing."},{"question":"What is the Group Code and Product Group for 1FK2104-4AK11-1SB0?","answer":"The Group Code is R220 and the Product Group is 9021.
