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,

Eliminate the Frustration of Touchy
Encoder Alignment
Mercury Solves this Problem for Good
Fussy alignment is no longer a concern. With Mercury’s
patented PurePrecisionoptics, 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.

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.
