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.

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.

This compact, fully-featured signal processing system performs the following functions: • Interpolation - up to 256X with 28.8 million quadrature states / sec. • Programmable interpolation level and output bandwidth • Accuracy optimization - sensor signals are automatically optimized to improve system accuracy and maximize repeatability • Signal strength indication - red / yellow / green LEDs assist during setup and provide diagnostics at a glance • Index centering - centers the bi-directional index output pulse for repeatability to +/-1LSB • Power-indicating LED • Computer interface - for programming and data acquisition using SmartPrecision software • Superior EMI / RFI immunity - CE compliant • Mounting options - all electronics are within the EMI-shielded connector housing and can be screwed directly into a mating connector that is bulkhead mounted, or the module may be mounted to the frame of your motion system and connected using an extension cable TM SmartPrecision module enclosure provides “Best-in-Class” noise immunity for high noise environments. Programmable Interpolation The electronics module has programmable interpolation that is selectable over the range x4 to x256 in integer steps, providing output resolutions that can be matched to your application requirements. This feature provides linear resolutions from 5µm to 0.078µm in convenient increments (e.g. x200 interpolation = 0.1µm) and rotary resolutions from 6,600 CPR to 4.2M CPR. Specify the interpolation value at the time of ordering or select the interpolation at your site using SmartPrecision Software.

By specifying the maximum output frequency to match your controller's capability - ranging from 900,000 up to 28.8 million quadrature state changes per second - the Mercury encoder system will never produce encoder counts faster than your controller can read them. Specify the encoder’s maximum output frequency at the time of ordering or select the setting at your site using MicroE's SmartPrecision Software. * The electronics module’s serial computer programming interface can be translated to be RS-232 compatible using the MicroE SmartPrecision Computer Interface Adapter or a voltage translation circuit of your own design. ** “Quadrature state changes per second" is the reciprocal of "dwell time" or "edge separation". For example, 28.8 million states per second = 0.035µsec dwell time. *** Future availability, contact MicroE. All Specifications are subject to change.
