Optimizing tolerance chains with BOGEN’s rotary magnetic scales

Smarter integration. Higher precision. Less complexity.

In high-precision system design, mechanical tolerances are a constant challenge. Small deviations across interfaces can quickly add up - causing misalignments, reduced performance, or costly rework.

BOGEN’s integrated rotary magnetic scales address this challenge by combining a high-precision magnetic ring (with optional carrier hub) and a dedicated sensor head. The result: compact, ready-to-integrate components that fit seamlessly into drive assemblies, even in the tightest spaces.

Technical advantages

• Simplified setup – magnetic ring and sensor form a matched pair → fewer components, reduced assembly effort.
• Streamlined integration – fast installation with consistent alignment; calibration effort depends on configuration.
• Robust technology – Nonius scales paired with AKS16, AKS17, and AKP18 sensor heads offer reliable, high-resolution feedback.
• Custom-fit – OEM-specific geometries for tight spaces or special requirements.

Real-world example: Compact robotic joints

In collaborative robots (cobots), joints must balance extreme precision with strict space limitations. Conventional encoder setups often require several components and complex calibration, which consume valuable space and increase assembly risks.

With BOGEN’s integrated rotary magnetic scales, the magnetic ring and sensor head form one compact unit - optimizing tolerance chains while delivering high-resolution, absolute position feedback within the joint axis.

Result → smoother joint movement, higher reliability, and faster production ramp-up.
