MicroE Systems revolutionized encoder technology with the original Mercury encoder
family. Smaller, faster, and smarter than anything before, it set the standard for innovation.
Now Mercury II takes another giant step forward by giving you “best-in-class”
performance, unparalleled versatility with tape and glass scales, superior robustness, and
unmatched ease of use. And you get all of this from a single system, without making
trade offs.

Mercury II was designed for robust operation under a wide range of conditions. We took a system-wide approach, starting with a completely new sensor design that resists scale contamination and electromagnetic interference. In addition, we designed new SmartPrecision II electronics to compensate instantaneously for any signal variations.


New Sensor Design

The new optical design provides contamination resistance to oil, fingerprints, dust, and more. AGC circuitry instantly compensates for signal variations.

Best-in-Class Noise Immunity

Digital output from the sensor to the interpolator makes Mercury II ideal for high PWM/EMI noise applications, supporting cable runs up to 5 meters from the sensor and 10 meters from the interpolator to the controller.


Fail Safe Limits

Mercury II has fail safe left and right limits with outputs to dedicated pins for easy integration with your controller.


Gain, Offset and Phase Correction

Mercury II ensures the highest accuracy with automatic signal optimization and real-time signal processing algorithms.
