Optical Rotary Encoder Smallest Sensor High Precision Analog Output System
Optical Rotary Encoder Smallest Sensor High Precision Analog Output System
Mercury TM 1200 PCB-Mount Analog Encoders.For Customer Interpolation- Resolution to 0.078μm
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.
Eliminate the Frustration of Touchy Encoder Alignmen,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.
