MII 1600 System Features at a GlanceThe Mercury II 1600 is built on the field-proven Mercury technology platform. Known for being smaller, smarter and faster, Mercury IIbuilds on the original Mercury series and adds increased performance, versatility, robustness, and ease-of-use. Convenient tape scale applicator tool insures consistency andspeeds installation Low power consumption - only 48mA with A, B and I outputsterminated Robustness features include all differential digital outputs anddouble-shielded cabling for superior EMI/RFI immunity; scalecontamination resistance insures encoder operation even withfingerprints, oil, dust and other forms of contamination Optional software makes setup, motoring and diagnostics easyPage 3Mercury II 1600s features include: Small, low-mass sensor with ultra low Z-height fits in compactmotion systems High-speed operation - 20m/s at x4 interpolation; 7.2m/s at x8,x20, and x40 interpolation High accuracy - long-range accuracy up to 5m/m(after linear correction in the customers controller) Built-in, high speed interpolation up to x40 in the sensor for up to0.5m resolution output Broad sensor alignment tolerances and the alignment toolsred/yellow/green setup LEDs make sensor alignment fast Adhesive-mount laser tape scalesupplied in continuous lengths forcut-to-length convenience andinventory savings; mounts onvirtually any surface - metals,granite, glass, composites,or ceramics Stick-on optical index can be placed anywhere,is easy to apply, and requires no adjustmentELECTROMATESold & Serviced By:Toll Free Phone (877) SERVO98Toll Free Fax (877) SERV099www.electromate.comsales@electromate.com 4. Smallest Sensor, Lowest System Height, Smallest TapeScale System, Broader Alignment Tolerances, and MoreWhy Mercury II Encoders Make It Easier To Design High Performance Into Your EquipmentMercury II Can Reduce System Size and CostMercury IIs system height with tape scale is 36% shorter than competitiveencoders, making it easier to fit into your design. This reduction can also cutmotion system weight and cost by allowing the use of smaller motors and stages.This significantly relaxes mechanical system tolerances, while reducing systemcosts. Mercury IIs optical index marker is placed within the 6mm width of thetape scale, saving even more space by eliminating external index and tapescale carrier bulk.Sold & Serviced By:Page 4Mechanical Dimension Comparison*Mercury II Brand X Brand Y Mercury II vs.with Tape Scale Best CompetitorSystem height 10.1mm 18.2mm 15.8mm 56% betterSensor Z height 8.7mm 12mm 14.8mm 38% betterStandoff tolerance 0.15mm 0.1mm 0.1mm 50% betterTape scale width** 6.0mm 16.0mm 15.3mm 155% better*Based on published specifications**Tape scale system width including indexEliminate the Frustration of Touchy Encoder AlignmentMercury II Solves this Problem for GoodFussy alignment is no longer a concern. With Mercurys patented PurePrecision optics,advanced SmartPrecision II electronics and LED alignment indicators, you can push thesensor against your reference surface, tighten the screws and youre finished. Try thatwith Brand X or Y.This performance is possible thanks to relaxed alignment tolerances, particularly in thetheta Z axis. Mercury II offers a 2 sweet spot thats a 300% improvement over thebest competitive encoder. And that will result in dramatic savings in manufacturing costs.No other commercially available encoder is easier to align, easier to use, or easier tointegrate into your designs.Lowest System HeightMercury IIBrand XBrand YTheta Z Alignment ToleranceSmallest Tape Scale System16mm15.3mm6.0mmAlignment Tolerance Comparison*Mercury II*** Brand X Brand Y Mercury II vs.Best Competitortheta Z 2.0 0.006 0.5 Mercury is 300% bettertheta Y 1.0 unspecified 1.0theta X 1.0 0.1 1.0*Based on published specifications***Measured at a constant temperature for one axis at a time with all other axes at their ideal positions. 2 0.006 0.510.1mm18.2mm15.8mmELECTROMATEToll Free Phone (877) SERVO98Toll Free Fax (877) SERV099www.electromate.comsales@electromate.com 5.
