Optical incremental linear encoder RGH41
- Production:
- Renishaw (United Kingdom)
- Encoder RGH41
When working with the open, non-contact reading head of the RGH41 encoder a RGS40-S unique scale tape with a step of 40 μm by Renishaw is used, with a resolution of up to 50 nm!
Features and benefits of the RGH41 reading head
A compact and robust reading head with an integrated interpolator provides digital and analog output signals that meet the industry standard.
- High speed and reliability of work with zero friction and no mechanical wear.
- Scale with a step of 40 microns allows you to work with wide tolerances when installing the reading head.
- Simple installation and setup procedure due to the presence of a special built-in LED indicator.
The patented optical signal filtering system guarantees high signal stability under conditions that do not allow the use of most open optical encoders.
- 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.
Scale tape RGS40-S with 40 μm steps
RGS40-S is made of a thin, flexible steel strip that is applied to the gold coating to provide high reflectivity and corrosion resistance. This tape can be fixed using a self-adhesive basis on most of the materials used in the industry, including metals, ceramics and composite materials.
- The tape is supplied on a reel, it is possible to cut parts of the necessary length, up to 70 m.
- Using the RGS-S ribbon allows you to simplify the temperature compensation thanks to its temperature characteristics to the characteristics of the base on which the tape is attached.
- There is a special device for fast and accurate installation of a scale tape.
- The lacquer coating of the tape is easy to clean and is resistant to external influences, which occurs when manipulating the tape.
- You can always cut a piece of any required length, which optimizes inventory management and minimizes waste.
- High accuracy of the linearity of the scale ± 3 μm / m ensures high overall accuracy with a simple adjustment procedure.
