0.4 kW at 3000 rpm — sized for the high-speed side of a small cell
The 1FK2104-4AF01-1SA0 is a SIMOTICS S-1FK2 HD servo motor from the 1FK2 family, targeted at the SINAMICS S210 drive platform — the pairing closes the cycle budget on small indexing tables, end-of-arm drives, and short-stroke gantries where 0.4 kW continuous at 3000 rpm is enough headroom. Stall torque is rated at 1.27 Nm with PN = 0.4 kW at nN = 3000 rpm on a 380–480 V supply, and PN = 0.2 kW at nN = 1500 rpm on a 200–240 V supply — the lower-voltage rating lets the same axis be powered from a 230 V-class drive on smaller cells. Encoder is the AS22DQC absolute single-turn, 22-bit, on the OCC interface; a rotatable M17 plug keeps the cable exit aligned with the cabinet routing when the cell layout changes.
IP65 housing, D19x40 feather-key shaft — built for the machine, not the bench
IP65 sealing covers the housing and shaft seal against coolant splash and cutting-fluid mist typical of a CNC tending cell or a washdown-adjacent pick station — the rating is on the body, not the connector face, so a sealed cordset is still required at the M17 to keep the wet end sealed. Shaft is D19 x 40 mm with a feather key, so a standard next-day coupling or pulley drops in without a custom bore; the 40 mm shaft length gives room for a small pinion or a bellows coupler without overhanging the bearing journal. Group Code R220 and Product Group 9021 are the procurement keys for matching this motor to the matching SINAMICS S210 line filter, brake resistor, and pre-fabricated OCC cable — wrong group code usually means the wrong cable set, not a different motor.
Lifecycle and ordering — active, made-to-order, quoted per BOM line
Lifecycle stage is current and the part is listed as active by Siemens; sourcing posture is production-quantity order, not shelf-stock — Product Class C, built to order, non-returnable, so order against the confirmed BOM quantity and do not stock-buy speculatively.
