Cell-side identity and pairing
The 1FL2102-4AG11-0MC0 is a SIMOTICS S-1FL2 low-inertia servo in the 20 mm shaft-height frame, sized at 100 W continuous (Pn=100 W) at 3000 rpm with a 0.32 Nm rated and 0.32 Nm stall torque (M0=0.32 Nm; Mn=0.32 Nm) — the equal Mn/M0 figure tells the integrator this is a continuous-duty frame without a peak-torque headroom margin to lean on in aggressive accel profiles. It belongs to the 1FL2 family intended to pair with the SINAMICS S200 drive line on a 200 V 3AC bus, which means the cable set, electronic nameplate and one-button tuning all flow through the S200 rather than a third-party controller — that handshake is the cell-side reason to stay inside the matched pair rather than mixing a 1FL2 onto a legacy SINAMICS V70/V90.
Mechanical and electrical envelope
The shaft is a plain (un-keyed) cylindrical finish, tolerance class N, with a holding brake fitted as standard — the brake locks the axis when the drive is disabled, which matters on vertical or gravity-loaded axes where a 100 W motor's back EMF alone won't hold position if power drops. Wiring lands on a hybrid connector (AM21) carrying both power and the 21-bit absolute encoder feedback in one overmolded body — one connector instead of a separate power plug and encoder D-sub keeps the cable bend radius tight at the cable carrier, which is the usual failure point on small-frame servos in motion. Sealing is IP65 with an oil seal on the shaft pass-through, so the motor survives coolant splash and light washdown but is not rated for full IP67 submersion or high-pressure food-grade cleaning — read that as cabinet-side or sheltered-axis duty, not outdoor or open food-zone mounting.
Lifecycle and ordering posture
Lifecycle stage is recorded as current, so this is an in-production frame on the Siemens catalog — no last-time-buy window applies, but the product class label flags it as made-to-order: returns against credit are not the channel's policy, so the BOM line should be sized to the build rather than padded with speculative spares. Each unit ships one per package (Quantity Unit 1 Piece) in a 315 x 182 x 172 mm pack, and the Siemens Group Code R220 / Product Group X0DJ pair is what the BOM and incoming-inspection system should reconcile against so a wrong-frame 1FL2 substitution gets caught at goods-in rather than at commissioning.
