VLT-series

Hollow Shaft Capacitive Absolute Rotary Encoders (25…247mm), Extreme Temperature +125°C

Designed to meet the requirements of the most demanding applications

The Netzer VLT-series of absolute rotary encoders is designed for extreme environments, offering high-precision motion control with an extended temperature range of -55°C to 125°C. Using contactless capacitive sensing, they ensure wear-free, longterm reliability for aerospace, defense, robotics, and industrial applications. Their hollow shaft, low-inertia design enhances integration, reduces system weight, and optimizes dynamic response. Built to withstand harsh conditions, the VLT series delivers stable, high-resolution feedback in missioncritical systems. From precision automation to aerospace controls, these encoders set a new standard for durability and performance.
