Incremental Rotary Encoder
ARX B 58
Semi-Hollow Shaft, 58 mm Body — Up to 20 mm Bore
Semi-Hollow Shaft, 58 mm Body — Up to 20 mm Bore
The ARX B 58 is a semi-hollow incremental encoder in a 58 mm body accepting shafts from 6 to 20 mm — the largest bore range in the ARX family. Available in optical (up to 20,000 PPR) or magnetic variants, it is designed for heavier-duty applications where larger shaft diameters are common. The magnetic variant offers reliable performance in dusty or contaminated environments.
Ordering note: ARX models combine two measurement families — specify optical (ARC) for maximum resolution and precision, or magnetic (ARS) for immunity to dust, oil, and condensation in harsh environments.
Semi-hollow shaft (6–20 mm bore) - accommodates larger shaft diameters
Optical or magnetic measurement options - choose for your environment
Optical up to 20,000 PPR - high-resolution for precision control
IP54 rated - protected against dust and water splash
58 mm aluminium body - heavier duty construction
Suited for larger machinery and shafts - cranes, presses, heavy automation
