Small Rotary Encoder for Automation Tasks : Reliable and Strong

VLX-100

The Netzer VLX-100 Absolute Rotary Encoder delivers up to 22-bit resolution with 0.006 Degree accuracy in an ultra-thin (<9 mm) and lightweight (<40g) package. Using advanced capacitive sensing technology, it ensures contactless, high-reliability performance, eliminating mechanical wear for long-term precision.

Designed for aerospace, robotics, and high-precision automation, the VLX-100 features a hollow, low-inertia design, reducing system mass and improving dynamic response. If you need high-resolution rotary feedback in a compact, high-performance form, the VLX-100 is the ultimate solution.
