Artos™ Absolute Magnetic Encoder System
Artos™ is an absolute magnetic encoder system designed for motion control applications as a feedback element for angle/position and velocity control loops. A highly reliable measurement principle and processing provide low position latency, high resolution and angular/linear velocity. The robust design protects the readhead from liquid ingress and high temperatures, so it remains undamaged even in extremely contaminated and hot environments. Benefits True absolute system High accuracy and resolution Suitable for highly dynamic control loops Robust design and great EMC compatibility SSI and BiSS bidirectional communication protocols Compatible with FlexAB Wide installation tolerances IP67 protection class

AksIM-4™ with Hiperface DSL Protocol
AksIM-4 is a non-contact, high performance off-axis absolute rotary encoder. It is designed for integration into applications with limited space. A hollow ring, true absolute functionality and Hiperface DSL protocol make this encoder suitable for compact servo motor applications. The AksIM-4 encoder system consists of an axially magnetised ring and a readhead. Features True absolute system Custom magnetic sensor ASIC Self-calibration option Low profile, non contact Benefits Reduced wiring complexity High speed data transmission Cost efficient Possibility for more compact motor design

AksIM-4 Dual Concentric
The AksIM-4 dual concentric high-performance encoder integrates two non-contact absolute rotary sensors in a single device. This innovative solution provides simultaneous motor and reducer position feedback in a robot joint for exceptionally smooth, synchronised, and accurate motion control. Its compact, space-saving design makes it perfect for advanced robotics and other applications where installation space is limited, without sacrificing accuracy, reliability, or performance. Features Two-in-one encoder solution Ultra-compact, low-profile design High accuracy and repeatability Multiturn counter option Immunity to external magnetic fields Benefits Saves space Reduces complexity in robotic joints Immediate feedback at power-up Reliable performance even in demanding environments

RTB20 High Resolution Magnetic Encoder
The RTB20 high-resolution magnetic encoder features 18-bit resolution in an ultra-compact Ø20 mm encoder board, delivering exceptional precision in the smallest footprint. Its compact and lightweight design makes it ideal for applications such as printing, industrial automation, motor control and instrumentation. Features Based on TMR sensor Incremental resolution up to 18 bit UVW signals for commutation up to 256 pole pairs Zeroing function Benefits Simple and fast installation Non-contact, frictionless design Miniature design, Ø20 mm Long-term reliability No hysteresis

FlexAB™ Absolute Magnetic Scale System for Large Diameters
FlexAB is a rubber-supported magnetic scale system with built-in tensioning mechanism compatible with Artos absolute rotary readheads. It is designed for installation on large shafts as an element of the position and speed control loop. The compact readhead has wide installation tolerances and offers industry-standard output types (SSI or BiSS) and parallel ABZ incremental signals for highly dynamic applications. The non-contact measuring principle ensures high reliability in demanding applications. Features Rubber spring profile supported scale with built-in tensioning mechanism Wide operating temperatures For external diameter installation For diameters from 500 mm to 2,500 mm Full circle measurements Substrate thermal expansion compensation Large allowable shaft diameter tolerance ±0.2 mm Benefits Ensures stable and consistent scale tension for reliable measurements Operates effectively in harsh or variable environments Easy installation on large shafts and rotary systems Suitable for a wide range of applications and machine sizes Enables accurate position measurement over full rotation Maintains accuracy despite temperature fluctuations Simplifies mounting and reduces precision machining requirements
