Self-aligned scales with magnetic technology

GIVI Misure, a producer of optical scales, rotary encoders, magnetic scales, digital readouts and position controllers, has introduced a new model of self-aligned scales, based on magnetic technology. The scales are available in two versions: an

incremental version with TTL push-pull or line driver signals (MTT), and an absolute version with CANopen protocol (MTB). Both versions are mechanically (and electrically, in the case of the MTT) compatible with the optical scale PBS-HR. The accuracy of the measuring system is verified in rigorous environmental and climatic conditions and documented in the certificate of metrological inspection, and it is such to guarantee an error lower than ±15µm and a repeatability of ±1 increment. Both versions offer resolutions up to 1µm. The electronic circuit is protected against inversions of polarity and short circuits. The reference indexes are placed all over the measuring length, at a constant step of 10mm, and are activated by the zero magneto set, which slides along the scale. The cable is suited to continuous movements and its output is adjustable.

MTT and MTB scales are symmetric, simplifying the purchasing process and stock management. In the case of use on press brakes it is sufficient to orientate the cable output and to properly position the zero magneto set, to make the same scale applicable to both right and left columns of the press brake. Both versions have an IP67 protection class, and are therefore suitable for applications in environments characterised by the presence of dusts or liquids. MTT and MTB magnetic scales are manufactured in Italy, at the Nova Milanese production plant, and all of the products have a two-year warranty against manufacturing defects.
