High Vacuum Encoders
Overview
MicroE’s Mercury™ and Mercury II™ Vacuum Encoders deliver high‑accuracy motion feedback in an exceptionally compact form factor, purpose‑built for high‑vacuum environments. These encoders are significantly smaller than comparable systems, faster to install, and easier to align, making them ideal for space‑constrained linear and rotary applications.
Each vacuum‑rated sensor is fully vented and constructed from vacuum‑compatible materials, supporting a 48‑hour bake‑out at 150°C. Colour‑coded bare leads simplify customer termination, while the miniature sensor design enables integration into tight mechanical envelopes without compromising performance.
Features
- Smallest sensor in its class — approximately one‑third the size of competing encoders
- Revolutionary bolt‑in alignment for rapid, repeatable installation
- Advanced SmartPrecision™ electronics built into a shielded D‑sub connector
- A‑quad‑B output with programmable interpolation for resolutions to 0.005 µm (linear) and 67.1 M CPR (rotary)
- LED setup indicators for sensor alignment and index location
- Bi‑directional index signal repeatable to encoder resolution
- Best‑in‑class noise immunity for harsh environments
