Mercury Digital Encoders

Compact, Integrated Digital Feedback Systems

Mercury Digital Encoders combine a miniature sensor, double‑shielded cable, connector options, and a linear or rotary glass scale into a single compact system. This integrated architecture gives OEM designers a high‑performance feedback solution that fits into extremely tight spaces while maintaining excellent signal quality and ease of installation.

The ultra‑low‑profile sensor mounts flush using simple screw holes and weighs just 1.6 g, making it ideal for compact motion stages, semiconductor tools, laboratory automation, and precision instrumentation. Multiple connector formats—including standard 15‑pin D‑sub, micro‑connector, and PCB‑mount options—support flexible integration across a wide range of platforms.

Factory‑set interpolation provides resolutions from 5 µm to 0.50 µm (linear) and 6,600 CPR to 655,000 CPR (rotary). A‑quad‑B output with a bi‑directional index ensures compatibility with standard motion controllers, while full EMI shielding protects signal integrity in electrically noisy environments. An alignment tool is available to simplify setup and reduce installation time.
