FLUX IND-ROT-069 Ultra-Flat Frameless Inductive Rotary Encoder (69 mm OD / 40.20 mm Bore)

Technical Overview: IND-ROT-069

The FLUX IND-ROT-069 (Standard Range) is an ultra-flat, frameless inductive PCB rotary encoder engineered for weight-critical and magnetically noisy environments where permanent-magnet or Hall-effect sensors suffer from stray-field interference. Featuring a 69 mm outer diameter, a 40.20 mm through-bore, an installed height of less than 6 mm, and a featherweight mass of just 9.0 g (stator) + 12.0 g (21.0 g total) (rotor), the IND-ROT-069 integrates effortlessly inside compact servo actuators and surgical or collaborative robot joints.

Delivering Up to 22-bit single-turn absolute resolution with an accuracy of ±0.020° (±72") and ultra-low signal latency (< 5 µs), the IND-ROT-069 operates at up to 6,000 rpm across a generous 0.50 mm nominal air-gap (0.20–0.80 mm range). Supplied in the UK by 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 (69 mm envelope, frameless geometry, low axial stack), the IND-ROT-069 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).
