Rotary Position Encoder : High-Performance Motion Control Sensor"

VLX-140

The Netzer VLX-140 Absolute Rotary Encoder delivers up to 23-bit resolution with 0.006 Degree accuracy, all in an ultra-thin (<10 mm), lightweight (<72g) form factor. Utilizing contactless capacitive sensing technology, it provides exceptional reliability and long-term stability, eliminating mechanical wear for superior performance.

Optimized for aerospace, robotics, defense, and high-precision automation, the VLX-140 features a hollow, low-inertia design, reducing system weight and improving dynamic response. When it comes to high-accuracy rotary feedback in a compact, cutting-edge package, the VLX-140 sets the new industry standard.
