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. Engineers can achieve dramatic improvements in system speed, throughput, and reliability, while reducing cost, size and weight. The Mercury 1500P series kit encoders make it all possible. The digital output sensors 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. Standard Features • Small PCB mount sensor • Sensor is 5.6mm (H) x 12.7mm (W) x 15.2mm (L) and weighs 2.6g • Resolution: Linear 5, 2.5, 1.0, 0.5µm; Rotary 6,600 to 655,000 CPR • Digital Differential Outputs: A-quad-B and Index window • Bi-directional Index window signal • Index mark at the center or end of the glass scale (linear) Table of Contents System & Sensor pg . 2 Specifications pg 3 -4 Scales pg . 5 - 6 Ordering Information pg. 6 Optional features • Glass scale length or diameter: Linear lengths from 5mm to 2m Rotary diameters from 12mm to 108mm Broader Alignment Tolerances, Increased Standoff Clearance, Smallest Sensor and More Why Mercury Encoders Make It Easier To Design High Performance Into Your Equipment Theta Z Alignment Tolerance ± 0.5° ± 2° Mercury Brand Y ± 0.006° Brand X Eliminate the Frustration of Touchy Encoder Alignment 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.

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.
