RENISHAW: RGH24 RGS20 LINEAR ENCODER SYSTEM READHEAD RGH24D50A00A
RG2 READHEADS(RGH24)

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.
Renishaw’s RGH24 series is a non-contact optical encoder system. The compact readhead features a set-up led indicator, unique filtering optics for excellent dirt immunity, and integral interpolation down to 10 nm. RGH24 offers proven reliable performance and value making it one of the of the most commonly applied encoder systems. The RGH24 reads the 20 µm pitch RGS20 gold tape-scale and outputs a choice of industry standard 1Vpp analogue or RS442 digital signals. RGS20 is suitable for mounting to most common engineering materials including metals, granites, ceramics and composites.The scale can be mastered to the axis substrate by means of a specially formulated pre-applied adhesive and epoxy fastened ‘end clamps’.This method ensures the differential movement between the scale and the substrate is close to zero, even throughout significant temperature swings. The RGH24 range has also proven to be resilient to conditions considered challenging for most open optical encoders. They have been installed by many of the world’s leading linear motion OEMs in a wide range of applications such as metrology, machine tool, electronics, semiconductor and FPD manufacturing
