VLX-35

The Netzer VLX-35 Absolute Rotary Encoder delivers up to 21-bit resolution with 0.035 mdeg accuracy in an ultra-thin (<7 mm) and ultra-lightweight (<8g) design, making it one of the smallest high-performance encoders available. Built with contactless capacitive sensing technology, it ensures wear-free operation for long-term reliability in precision motion control systems.

 

Engineered for aerospace, robotics, medical devices, and compact automation systems, the VLX-35’s hollow, low-inertia structure reduces system weight and enhances dynamic response. If you need high-accuracy rotary feedback in the most compact form factor, the VLX-35 is the ultimate solution for space-sensitive designs.
