Encoders with Precision Scaling for Demanding Environments

VLT-100

The Netzer VLT-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. Utilizing advanced capacitive sensing technology, it ensures contactless, high-reliability performance, eliminating mechanical wear for long-term precision.

Engineered for aerospace, robotics, and high-precision automation, the VLT-100 features a hollow, low-inertia design, reducing system mass and improving dynamic response. Need high-resolution rotary feedback in a compact, high-performance form? The VLT-100 is the ultimate solution.
