The reading head of the linear encoder RGH26 <\/b> is specially designed for use with the Mitsubishi MELSERVO J2S and J3 servo amplifier series. Unlike other linear encoders with a serial interface, the RGH26 head does not require a separate interface. All electronics, interpolation devices and data conversion, transmitted in series, are enclosed in a compact package similar to the popular RGH22 model. When working with the RGH26 encoder head, a unique scale RGS20-S ribbon with a 20 μm pitch of Renishaw is used; at the same time, a resolution of up to 0.5 μm is achieved.\n<\/p>\n
\n Characteristics and advantages of the reading head RGH26 <\/b>\n<\/p>\n
\n – Compact and robust reading head with built-in interpolator provides serial data transfer compatible with Mitsubishi system formats.
\n – The non-contact design provides high speed and reliable operation with zero friction and no mechanical wear.
\n – The reading head reads in increments (with a certain step), which gives a high degree of immunity to interference.
\n – Simple procedure for installing and setting the reading head due to the presence of a special built-in LED indicator.
\n The optical signal filtering system guarantees high signal stability in conditions that do not allow the use of most open optical encoders.
\n – The zero mark ensures the repeatability of the initial position, and the limit switches – the automatic signal giving the initiating stop of the moved node.\n <\/p>\n
\n Scale tape RGS20-S with a pitch of 20 μm
\n<\/b>\n<\/p>\n
\nRGS20-S tape with a pitch of 20 microns is made of a thin flexible steel strip, which is coated with gold to provide high reflectivity and corrosion resistance. This tape can be fixed, using a self-adhesive base, on most materials used in the industry, including metals, ceramics and composite materials.
\n – The tape is supplied on a reel, it can be cut off parts of the desired length, up to 70 m.
\n RGS20-S tape has temperature characteristics corresponding to the characteristics of the substrate on which the tape is attached, which simplifies the process of compensating for the effect of temperature.
\n – A special device is provided for fast and accurate installation of the scale tape (patented).
\n The lacquer coating of the tape is easy to clean and is resistant to external influences that occur when manipulating the tape.
\n You can always cut a piece of any necessary length that optimizes inventory management and minimizes waste.
\n – High accuracy of linearity tolerance of \u00b1 3 μm \/ m provides high overall accuracy with simple adjustment procedure.\n<\/p>\n
