Broader Alignment Tolerances,

Increased Standoff Clearance, Smallest Sensor and More

Why Mercury Encoders Make It Easier To Design High Performance Into Your Equipment

Page 3 of 10

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.

Alignment Tolerance Comparison**

Mercury* Brand X Brand Y Mercury vs. Best Competitor

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.

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.
