Low Outgassing Encoder for Precision in Sensitive Environments

VLT-60

The Netzer VLT-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. Its contactless capacitive technology ensures reliable, wear-free performance, making it ideal for aerospace, robotics, and high-end automation.

Featuring a hollow, low-mass design, the VLT-60 simplifies integration, reduces system inertia, and enhances overall efficiency. Seeking top-tier precision in a compact form? The VLT-60 sets a new standard in rotary feedback technology.
