Definition and role in the SINAMICS S200 axis
The 1FL2104-4BF11-1HC0 is a SIMOTICS S-1FL2 low-inertia servo motor from Siemens, designed as the rotating axis on the matched SINAMICS S200 drive — a 400 V 3AC unit with a rated power of 1 kW, a rated speed of 3000 rpm, and identical rated and stall torque figures of 3.2 Nm, which simplifies the sizing step against the load inertia for the integrator. The shaft height is 40 mm and the motor ships with a shaft key (tolerance N) and an integrated holding brake; the encoder is the 17-bit single-turn AS variant with a hybrid connector, so the same cable set works for power and feedback between the S200 drive and the motor.
Mechanical and environmental envelope
Protection class on the motor body is IP65 with oil-sealed cable entry, meaning the housing is dust-tight and resists low-pressure water jets — adequate for a control-cabinet-mounted axis or a sheltered machine interior where occasional coolant or oil mist is present, but not a washdown zone. A holding brake is fitted, so the axis holds position when the drive enable is removed; combined with the keyed shaft (tolerance N), the unit drops straight onto a gear- or coupling-mounted load without additional keyed-component sourcing.
Production status and ordering path
Production status for the 1FL2104-4BF11-1HC0 is recorded as active (lifecycle stage current), and each unit ships as a built-to-order item — the product class flags it as a product manufactured or produced to order, so it is not a freely returnable stocked line and volume quantities are quoted against the BOM. RoHS compliance has been declared since 01-01-18 and REACH Article 33 information is supplied, so the declaration pack for the panel builder or end-customer covers the European environmental data set without an extra document chase.
Procurement and catalog admin notes
Punch-out and tail-spend consolidation: quoting the order code on the RFQ returns current price-break and lead-time figures against the requested quantity, and because the product class flags it as built-to-order (1 Piece = 1 Piece base), the RFQ line is what triggers production scheduling at Siemens — there is no shelf stock to pull from a preferred catalog. Internal catalog references group this motor under Group Code R220 / Product Group X0DK, with packaging dimensions of 382 × 222 × 240 mm for one piece — useful for the indirect-spend buyer aligning the PO with the manufacturer's logistics record and stocking-cabinet footprint planning.
