RENISHAW: RGH22 RGS20 LINEAR ENCODER SYSTEM READHEAD RGH22X30R00A
RG2 READHEADS

Renishaw’s RG2 linear encoder system is a noncontact optical encoder designed for position feedback solutions. The system uses a common refl ective tape scale scanned by a readhead chosen from a range of options offering industry standard digital square wave or analogue sinusoidal output signal formats. Renishaw’s patented optical scheme is used in all readhead series and gives proven performance benefi ts together with high tolerance to scale contamination. The RGH22 range is suitable for use in a broad range of applications, offering high resolution and high speed with stability and reliability. A dual limit sensor option is also available offering two dedicated signal outputs, left and right end-of-axis travel indication. RGH22 is an ideal feedback solution wherever precision controlled movement is required. The RGH22 readheads offer the full set of RG2 features and integral interpolation in a robust package, with an integral set-up LED for quick and easy installation. Common applications include co-ordinate measuring and layout machines, semiconductor/electronics manufacturing and inspection, height gauges, electronics assembly and test, linear motors, digital image setters and a variety of custom linear motion solutions.
