VLP-35

The Netzer VLP-35 Absolute Rotary Encoder delivers up to 19-bit resolution with 0.035 Degree accuracy in an ultra-thin (<7 mm) and ultra-lightweight (<8g) package, 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.


Optimized for aerospace, robotics, medical devices, and compact automation systems, the VLP-35’s hollow, low-inertia structure minimizes system weight and enhances dynamic response. If high-accuracy rotary feedback in a compact form factor is required, the VLP-35 offers an unparalleled solution for space-sensitive applications.
