Vacuum Compatible Encoders

Vacuum-compatible encoders provide precise position feedback in environments where traditional encoders would fail due to outgassing, material limitations, or pressure sensitivity. These encoders are essential for applications in semiconductor manufacturing, aerospace, scientific research, and medical equipment, where maintaining a controlled vacuum environment is critical.

Electromate offers high-performance capacitive vacuum-compatible encoders from Netzer and KappaSense, designed for ultra-precise motion control in demanding conditions.


Netzer VLS Series Encoders

The Netzer VLS series is a COTS, space-qualified absolute rotary encoder designed for high-precision motion control in aerospace and LEO systems. It uses contactless capacitive sensing to eliminate mechanical wear, supporting stable performance over extended missions in harsh environments.

The hollow shaft and low-inertia construction improve dynamic response while minimizing overall system mass. The series ranges from compact models such as the VLS-25 to higher-accuracy options like the VLS-247, each built to meet the strict requirements of space applications.

The VLS lineup is engineered for consistent, reliable encoder feedback in mission-critical environments.


FREEe Vacuum Compatible Linear Encoders

The KappaSense FREEe™ linear encoder features a cable-free, ultra-light readhead, reducing friction and wear for long-term reliability.

With a resolution down to 0.5 µm and stroke lengths up to 800 mm, it delivers high-precision position feedback for CNC machining, medical robotics, and automation.

Its compact design and non-contact sensing make it ideal for applications requiring smooth, high-speed motion in challenging environments.
