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.

Mercury

Brand X

This performance is possible thanks to relaxed alignment

tolerances, particularly in the theta Z axis. Mercury offers a

2ꢀ sweet spotꢁ 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 clearanceꢁ 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.

SmartPrecision

Electronics Module

The Mercury 2000 encoder system includes a SmartPrecision

electronics module. 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

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.

Programmable Maximum Output Frequency

For encoder applications combining high resolution and high speed,

the SmartPrecision electronics module supports up to 28.8 million

quadrature state changes per second**. By specifying the maximum

output frequency to match your controller's capability - ranging from

ꢂ00,000 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

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 need-

ed. 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.ꢂ5mm 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.
