Analog Sine/Cosine and Digital Index Window
The Mercury 1000 encoder system includes the sensor, double shielded cable, connector, and either a linear or rotary glass scale. Mercury's space-saving, integrated configuration gives OEM system designers a breakthrough in performance.
Imagine what you can do with this!
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 SmartPrecisionTM 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 interpolation electronics to achieve the resolution required by your application.

Broader Alignment Tolerances, Increased Standoff Clearance, Smallest Sensor and More
Why Mercury Encoders Make It Easier To Design High Performance Into Your Equipment Theta Z Alignment Tolerance Eliminate the Frustration of Touchy Encoder Alignment Mercury Solves this Problem for Good
Fussy alignment is no longer a concern. With Mercury's patented PurePrecisionTM optics, advanced SmartPrecisionTM 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.

Standoff Clearance 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.

Scale Specifications
Standard and Customized Scales
MicroE Systems offers a wide array of chrome on glass scales for the highest accuracy and best thermal stability. Easy to install, standard linear and rotary scales meet most application requirements. Customized linear, rotary, and rotary segment scales are available where needed. All scales include an optical index. Mercury's glass scales save time by eliminating motion system calibrations or linearity corrections required by other encoders, and provide better thermal stability than metal tape scales. Options include: * Standard linear: 18mm - 2m * Standard rotary: 12mm - 107.95mm diameter, with or without hubs * Custom linear*: special lengths, widths, thickness, index mark locations and special low CTE materials * Custom rotary*: special ID's, OD's (up to 304.8mm), index mark outside the main track and special low CTE materials * Mounting of hubs for rotary scales: MicroE Systems can mount and align standard, custom, or customer-supplied hubs * Rotary segments*: any angle range; wide range of radius values *Custom scales or rotary segments are available in OEM quantities. Contact your local MicroE Systems sales office.
