Shaft height 52 mm and the 2 kW continuous rating mark it as the mid-frame option in this line — large enough for conveyor indexing and small packaging machinery, compact enough for benchtop assembly cells. ## Key ratings and what they mean Supply voltage 400 V 3AC with a 2 kW rated power (Pn) and 3000 rpm rated speed (Nn) sets the operating envelope; the 8 Nm stall torque (M0) versus 6.6 Nm rated torque (Mn) tells you how much acceleration headroom the motor carries before the continuous curve takes over. That M0/Mn margin matters on cyclic loads with rapid accel/decel profiles — the S-1FL2 line is tuned for those dynamics rather than steady-torque duty. The AM21bit absolute encoder and integrated holding brake come standard on this variant. The holding brake is what holds the load at standstill after a servo disable — its presence on the part number (-0MB0 suffix) is the difference between this configuration and a brake-less build that would need an external mechanical lock on vertical axes. IP65 protection class with an oil seal on the shaft. The oil seal excludes the light oil mist and coolant splash common in machining cells and small bottling lines; in a cleaner cabinet build the seal can sometimes be omitted on other variants, but here it is part of the rated enclosure. Plain shaft, tolerance N — a straightforward machine fit without a keyway. ## Group code, product group, and order data Ordering data: Group Code R220, Product Group X0DK, product class C — built to order per the configured option set, which is why returned units are not credited. Quantity unit and packaging quantity both read 1 piece, and the shipping carton measures 432 x 222 x 240 mm. ## Compliance posture RoHS substance restriction compliance has been in force since 01-01-18, and Reach Article 33 duty-to-inform is satisfied per current candidate-list reporting. Export-control classification AL:N / ECCN:N means no special-export licensing is triggered for typical cross-border shipments.","metaTitle":"Siemens 1FL2105-4AF11-0MB0 Servo Motor, 2 kW, IP65","metaDescription":"Siemens 1FL2105-4AF11-0MB0 SIMOTICS S-1FL2 servo motor, 2 kW, 8 Nm, IP65, paired with SINAMICS S200.
