LENZ Encoders design and manufacture high-precision inductive absolute angle and linear encoders for robotics, industrial automation, and motion control systems. Our bearingless, non-contact position sensors provide reliable angular feedback in the most demanding environments, from collaborative robots and factory automation, to aerospace-grade drives. These encoders offer resolutions up to 24 bits, high speeds (up to 60,000 rpm), and robustness against EMI, magnets, and harsh environments. Specialties: Inductive absolute angle and linear encoders (bearingless, non-contact sensing technology eliminates mechanical wear) High-resolution angular feedback up to 24 bits for servo and motion control Compact maintenance-free PCB encoders for robotics, cobots, and exoskeletons Harsh-environment encoders for aerospace, aviation, and industrial machinery BiSS-C and other digital feedback interfaces, reference designs, and firmware tools

The IRS Series are ultra-lightweight, two-PCB modular angle encoders offering 17-18 bit absolute position feedback with high accuracy. Available in diameters from Ø34 mm to Ø90 mm, these compact bearingless encoders integrate directly into servo motors, collaborative robots, and space-constrained automation systems. With 100% immunity to EMI and magnetic fields, a BiSS-C digital interface (SSI compatible), and a non-contact inductive design that eliminates mechanical wear, the IRS Series delivers reliable, maintenance-free performance across demanding industrial environments.

The ACTIS Series combines a PCB stator with an aluminum rotor to deliver arcsecond-level accuracy with 20-22 bit resolution. Models range from Ø39 mm to Ø150 mm (SAB039 to SAB150), achieving accuracies from ±44 to ±12 arcseconds - purpose-built for servo drives, CNC machine tools, precision instrumentation, and high-performance industrial automation. Non-contact inductive sensing, 100% EMI and magnet immunity, and a BiSS-C interface (SSI compatible) make the ACTIS Series the benchmark for precision angle measurement.

The ILS Series delivers high-precision absolute linear position measurement with no contact and no homing required, using LENZ's original inductive sensing technology. Measurement ranges span 2 mm to 1,000 mm with resolution down to 100 nm and repeatability better than ±1 µm. Immune to oil, coolant, dust, and magnetic interference, the ILS Series operates reliably from −40°C to +125°C. Simple installation make it the practical choice for CNC machine axes, linear actuators, semiconductor equipment, aerospace telecommunications, and industrial automation systems.
