The Mercury 1500 encoder system includes the sensor, double shielded cable, your choice of connector, and either a linear or rotary
glass scale. Mercury’s space-saving, integrated configuration gives OEM system designers a breakthrough in performance.
Imagine what you can do with this!
Reduce the cost and size of your system, and increase its performance all at
once. MicroE Systems’ Mercury 1500 kit encoders are available in two
styles. The M1500S, an RS-422 compliant 15 pin standard D-sub connector
and the M1500H, an RS-422 compatible 5x2 micro-connector for tight
spaces. Simply stated, the M1500 is smaller, higher performance, faster to
install, and easier to use than any other encoder. The tiny sensor fits into
very tight spaces, has broad alignment tolerances for fast and easy setup
and works in both linear and rotary applications. The entire Mercury 1500S
encoder is EMI shielded for use in the toughest environments. With
standard digital A-quad-B output, select the Mercury 1500 encoder with the
resolution required by your application.

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.
Brand X
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 its 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.
