Mercury II™ Family of
High-Performance Encoders

Models with Ultra-Small Sensors

Models with All Electronics in the Sensor

Now with PurePrecision™
Laser Tape and
Glass Scales


MicroE Systems revolutionized encoder technology with the original Mercury encoder family. Smaller, faster, and smarter than anything before, it set the standard for innovation. Now, Mercury II takes another giant step forward by giving you all this, plus more performance, versatility, robustness and ease of use - without making trade-offs.

Choose the Mercury II models that match your applications:




Smallest Sensor in its Class
With Mercury II, you get the
smallest 1.2nm capable
sensor for compact system
designs. Plus, all electronics
are in the sensor for highest system
reliability and a smaller footprint.







Broadest Alignment Tolerances for Easy Installation
and Setup

Mercury II has the broadest alignment tolerances in the
industry, a full ±2 degrees. That makes it the easiest and
the fastest sensor to align and setup.






Stick-on Optical Index
& Limits for Tape & Glass Scales

Mercury II’s stick-on optical index is bi-directional
and repeatable at full speed. Install index markers
on laser tape or linear glass scales. Stick-on optical
limits work with MII6000 and MII5000 models.






PurePrecision Laser Tape in
Continuous Lengths up to 30 Meters

Cut-to-length laser tape scale reduces inventory costs and long lead times. The unique dispenser is convenient for cutting tape scale to length and for storage.
