3000Si Dual Axis Averager

Encoder Systems

Motion Control Feedback Using Average of Two Sensors

Reflective Linear and Rotary Encoder Systems

Imagine what you can do with this!

The Mercury 3000Si Dual Axis Averager provides unprecedented performance for high-accuracy rotary

positioning applications. By averaging two Mercury encoder sensors at high speed, your motion system

can use the average of the two signals directly for motion control feedback. Using two diametrically

opposed sensors, eccentricity errors are eliminated and rotary accuracy is increased. The industry-

standard SPI serial data interface is ideal for encoders and produces extremely high resolution at high

motion speed - up to 30X faster than A-quad-B encoders. The SPI standard is supported by many DSP

chip manufacturers and is easy to implement in your OEM controller design.

Mercury sensors are smaller, higher performing, faster to install, and easier to set up and align 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 new Mercury 3000Si Dual Axis Averager encoder system provides unique capabilities for motion control. With real-time feedback

of two encoders plus averaging (or difference), smallest sensor size, and easiest alignment, performance capabilities are unmatched.

Standard features

• Averages (or calculates the difference of) two Mercury sensors at high speed for feedback

in high speed, high-resolution servo control - see page 4 for specifications

• Small sensor with ultra-low Z height and broad alignment tolerances

• Advanced SmartPrecision electronics built into shielded D-sub connector

• Serial Word output with interpolation in binary steps for resolutions to 0.020µm* (linear);

16.8M CPR (rotary)

• LED set up indicators for easy sensor alignment and index location

• Bi-directional index signal is repeatable to encoder resolution

• Provides ultra-high accuracy for rotary positioning tables and rotary actuators - Averages two

sensors to virtually eliminate eccentricity errors while maintaining high resolution and speed.

• Provides robustness for linear or rotary applications by enabling redundant sensors and real-time

monitoring of the difference between the sensors - instantly detect a fault if an unexpected

difference exists.

• Useful for centering rotary scales during motion system setup for maximum accuracy.

Applications

* Resolution values shown are approximate - see page 4

for exact values.
