FLUX IND-MAX-250-AL Rugged Encapsulated Inductive Angle Encoder (250 mm OD / 200 Bore)

Technical Overview: IND-MAX-250-AL

The FLUX IND-MAX-250-AL (base model IND-MAX-250) is a heavy-duty, fully encapsulated bearingless inductive angle encoder manufactured by FLUX GmbH for demanding industrial, defense, aerospace, and subsea motion systems. Precision-machined from anodized aluminium (-AL) with an optional electroless nickel plating (Option N), the IND-MAX-250-AL combines a 250 mm outer diameter, a 200 mm through-bore, and a low 10.95 mm axial stack height with complete immunity to external electromagnetic fields, permanent magnets, oil, dust, and moisture.

Providing single-turn absolute resolutions Up to 23-bit at rotational speeds up to 6,000 rpm across accuracy Grades C, D, E, F (±14"), G (±10" std / ±7" Opt C), the IND-MAX-250-AL is sealed to IP67 as standard and configurable up to IP68 (Option W) and 200 bar subsea pressure (Option H). Conventional optical encoders risk glass disc fracture and readhead contamination under heavy shock or washdown, while Hall-effect magnetic encoders drift near high-current servo motor windings. FLUX 360° holistic inductive scanning eliminates permanent magnets entirely, achieving complete immunity to stray electromagnetic fields and particulate contamination.

Mechanically engineered for compact axial envelopes (250 mm envelope, 200 mm, 10.95 mm), the IND-MAX-250-AL installs directly onto hollow-shaft actuators, rotary tables, and gimbals without dedicated encoder bearings or wear-prone couplings. Supplied across Great Britain by TORQUETY LTD (UK Company No. 17124704, Covent Garden, London WC2H 9JQ & Oxford Engineering Desk +44 1865 679185), every unit is backed by local UK application engineering, 3D STEP CAD integration review, and tailored commercial quotations in Pounds Sterling (GBP).
