The Mercury 1200 encoder is an analog output system. Designed for PC board mounting, it is available with linear or rotary scales. Mercury's space-saving, integrated configuration gives OEM system designers a breakthrough in performance.
Imagine what you can do with this!
OEMs can now use encoders for closed loop control where it was previously not possible or cost effective. Using your interpolation electronics, engineers can achieve dramatic improvements in system speed, throughput, and reliability, while reducing cost, size and weight. The Mercury 1200 series kit encoders make it all possible. The analog output sensors can mount directly on your printed circuit board within an EMI shielded module. The low Z height of the sensor, only 5.6mm, opens up exciting design possibilities. OEMs that want to incorporate our interpolation electronics can contact MicroE for chip set or daughterboard solutions.

Broader Alignment Tolerances, Increased Standoff Clearance, Smallest Sensor and More
Why Mercury Encoders Make It Easier To Design High Performance Into Your Equipment 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.

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 it's 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.
