MPLS Slim & Simple Linear Position Detector Series


The MPLS series is a high-performance scale capable of detecting a linear axis’s position, with a resolution of 0.05 μm and a pitch accuracy of 10 μm. They use a newly developed detection pattern to receive scale-generated signals without interference, eliminating the need for scale wiring. In addition, the latest MPLS series, which has, inside its head, an A/D converter’s function to convert a scale-generated electric signal into a digital one, needs to use only its scale and head to transmit/receive signals to/from a machine’s control unit.


These technological developments have eliminated the need for scale wiring and A/D converters, while the reduced number of required components and the shortened manufacturing process have achieved a low price and a short delivery lead time for the product.


With respect to the installation compatibility with other companies’ products, the MPLS series uses a product length and mounting hole intervals that are the same as those of other companies' products. Furthermore, with a longer measurement length, the MPLS series can widen its measurement range or reduce its installation space.


The newly developed free user-assisting software can switch to output specifications that meet the type of a control unit, and fine-tune the matching between a machine and the location detector, to contribute to location detection under optimum conditions.
