Renishaw: RGS20-S TAPE SCALE (A-9517-0004)
RGS20-S 20 µm pitch tape scale

20 µm RGS20-S is manufactured from a thin flexible steel strip, which is gold plated to give high reflectivity and corrosion resistance. It may be mounted, using adhesive backing tape, to most engineering materials, including metals, ceramics, and composites.

Scale is supplied on a reel and can be cut to suit any axis length up to 70 m

RGS-S scale matches the thermal behaviour of the substrate it is affixed to, simplifying thermal compensation

Applicator tool enables fast and accurate scale installation

Lacquer coated scale is easy to clean and resistant to handling

'Cut-to-measure' convenience ensures minimum waste and efficient inventory management

±3 µm/m linearity enables high accuracy with simple compensation

RGS20-S is a robust, 6 mm wide stainless steel encoder tape scale with a thickness of 0.15 mm. This allows the scale, when rigidly fixed to a machine axis, to become ‘mastered’ to the machine substrate, matching its thermal expansion coefficient and behaviour. Differential movement between the scale and the machine is thus minimised, improving the metrological performance that can be achieved with simple thermal system compensation.
RGS20 scale: • ‘Cut-to-length’ convenience • Lengths from 100 mm to over 50 m • Protective lacquer or tough polyester coating option for applications using harsh solvents • Efficient, accurate installation • Affixes to most common engineering materials • Self-adhesive backing tape • Applicator tool allows scale to be installed using the motion of the axis
