Compact Rotary Position Sensor : High-Accuracy Performance

VLX-60

The Netzer VLX-60 Absolute Rotary Encoder delivers up to 22-bit resolution with accuracy reaching 0.01 Degree, all in an ultra-thin (<8 mm) and lightweight (<16g) form factor. Its contactless capacitive technology ensures long-term reliability with no mechanical wear, making it ideal for aerospace, robotics, and high-end automation.

Its inherently hollow, low-mass design simplifies integration, reducing system inertia and enhancing overall performance. Who else delivers this level of precision in such a compact package?
