Incremental Rotary Encoder (Magnetic)
ARS B 38
Semi-Hollow Shaft, 37 mm Body — 4 to 10 mm Bore
Semi-Hollow Shaft, 37 mm Body — 4 to 10 mm Bore
The ARS B 38 is a semi-hollow shaft magnetic incremental encoder in a compact 37 mm body. The semi-hollow design accepts shafts from 4 to 10 mm, allowing direct mounting without couplings. The magnetic measurement principle gives reliable operation in dusty, oily, or humid industrial environments where optical encoders would require additional protection.
Semi-hollow shaft (4–10 mm bore) - direct mounting without couplings
Magnetic measurement - reliable in dusty, oily, and humid conditions
Up to 1,024 PPR - suitable for speed and position feedback
3,000 RPM operating speed - covers most industrial motor applications
IP54 rated - protected against dust ingress and water splash
Compact 37 mm body, ~110 g - minimises load on motor bearings
