Reduce the cost and size of your system, and increase its performance all at once. MicroE Systems’ Mercury 1000 kit encoders are smaller, higher performance, faster to install, and easier to use than any other encoder. Advanced features include SmartPrecision ™ automatic offset and gain adjustments during set up to optimize accuracy. No manual adjustments are needed.The tiny sensor fits into very tight spaces, has broad alignment tolerances for fast and easy setup and works in both linear and rotary applications. The entire Mercury 1000 encoder system is EMI shielded for use in the toughest environments. With standard analog sine/cosine output, use your interpolationelectronics to achieve the resolution required by your application. The Mercury 1000 encoder system includes the sensor, double shielded cable, connector, and either a linear or rotary glass scal e. Mercury’s space-saving, integrated configuration gives OEM system designers a breakthrough in performance.

Eliminate the Frustration of Touchy Encoder Alignment Mercury Solves this Problem for Good Fussy alignment is no longer a concern. With Mercury’s patented PurePrecision™ optics, advanced SmartPrecision™ electronics and LED alignment indicators, you can push the sensor against your reference surface, tighten the screws and you’re finished. Try that with brand X or Y. This performance is possible thanks to relaxed alignment tolerances, particularly in the theta Z axis. Mercury offers a ± 2° sweet spot– that’s a 300% improvement over the best 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 to integrate into your designs. Broader Alignment Tolerances, Increased Standoff Clearance, Smallest Sensor and More Why Mercury Encoders Make It Easier To Design High Performance Into Your Equipment Alignment Tolerance Comparison** Mercury* Brand X Brand Y Mercury vs. Best Competito r Z Standoff ± 0.15mm ± 0.1mm ± 0.1mm Mercury is 50% better Y ± 0.20mm for linear ± 0.1mm unspecified Mercury is 100% better ± 0.10mm for rotary 19mm dia. theta X ± 1.0° unspecified ± 1.0° theta Y ± 2.0° ± 0.1° ± 1.0° Mercury is 100% better theta Z ± 2.0° ± 0.006° ± 0.5° Mercury is 300% better *Measured at a constant temperature for one axis at a time with all other axes at their ideal positions. Based on published specifications Mercury Can Reduce System Size and Cost Mercury’s sensor height is 44% shorter than competitive encoders, making it easy to fit into your design. This reduction can also cut total system weight and cost by allowing the use of smaller motors and stages. Safe system operation is also enhanced thanks to Mercury’s generous standoff clearance– 200% greater than other encoders. And its standoff tolerance is 50% greater than the best alternative. This significantly relaxes mechanical system tolerances, while reducing system costs.
