With Mercury II, you get the smallest 1.2nm capable senYou get laser tape or glass, linear and rotary scales. Youget adhesive-mount laser tape in continuous lengths on reup to 50 meters, and the only stick-on optical index and markers. You get the widest alignment tolerances, plusinstrument free setup. Finally, setup programmability,monitoring, and diagnostic capabilities are standard withSmartPrecision II Software.

The Best Features of Tape and Glass, Plus Stick-on

Optical Index and Limit Markers

Only Mercury II lets you use the same sensor with PurePrecislaser tape for convenience, or with linear and rotary glasscales for the highest accuracy. Whats more, our stick-onoptical index achieves bi-directional repeatability of 1 LSBfull speed. Index and limit markers will work with both lasetape and linear glass scales.

MicroE Systems revolutionized encoder technology with theoriginal Mercury encoder family. Smaller, faster, and smarterthan anything before, it set the standard for innovation. Now,Mercury II takes another giant step forward by giving youbest-in-class performance, unparalleled versatility, superiorrobustness, and unmatched ease of use. You get all of thisfrom a single system, without making trade- offs.

The Highest Resolution

The Highest Accuracy The Highest Speed

Mercury IIs best-in-class performance is the result of its next-generation optical design, and SmartPrecision II electronics.This combination enables best-in-class speed, best-in-class resolution, and best - in - class accuracy, all from asingle encoder family.

The Highest Resolution

Mercury II has user selectable resolutions from 5m to1.2 nm linear, or 20k CPR to 268M CPR rotary. Users can

also set the interpolation level in integer steps for precise control.

The Highest Accuracy

Mercury II gives you the high level of short-travel accuracypreviously expected only from fine pitch glass systems.

The Highest Speed

Mercury II operates at speeds over two times faster thancompetitive encoders with A-quad-B output. For example,maximum speed at 0.1m resolution is 4m/s; the closest com-petitor is1.5m/s.

Mercury II can operate at speeds of 4m/s with a resolution of 0.1mThats over two times faster than competitive 20m encoders usingA-quad-B output, and accuracy is equivalent to a fine pitch system

with the SmartPrecision II interpolator electronics,allowing encoder setup and diagnostics using

programmable features, data plots, and real-time indicators.

It adds Ethernet connectivityfor secure remote monitoringand control via an Internetconnection, and it allowsusers to view and controlall parameters remotely even from multiplelocations, simultaneously.

PurePrecision Laser Tape,the Next Generation Tape ScalePurePrecision laser tape is the easiest tape to installand use. Cut it to any length you need; adhesivebacking and our unique application tool make installa-tion fast and accurate. The tape is available in reelsup to 50 meters in length, or you can order pre-cutlengths if you prefer. PurePrecisionlaser tape is an easy way to

reduce both manufacturingcosts and longlead times.

The Only Stick-On

Optical Index and Limits

Cut-to-length tape scales require anadjustable index. Hall sensors are too

large and too hard to install. Mercury IIsolves this problem with the first and onlystick-on optical index and limits. Place themarkers along the tape scale for unmatchedflexibility, or use them with glass scales forrapid prototyping. The in-track bi-directionaloptical index provides 1LSB repeatability,and operates at all encoder speeds.Separate fail-safe left and right opticallimits also enhance motion system safetyand reduce cabling.

Step One:

Apply Tape to Substrate

Simply cut the desired length

from the reel, feed it into theinstallation tool, and roll it outalong a benching edge. Thetool peels off the tape scalesadhesive backing and appliesuniform pressure over the tape scalessurface as it is rolled out. The tapecan then be fixed at its ends,matching it to the thermalperformance of the substrate.
