Renishaw’s RGH24 series of incremental gratings, featuring the RGS20 linear gold-plated scales, has been a trusted solution in the position feedback market for many years. Widely recognized as an industry benchmark, it continues to be a popular choice among customers due to its reliability, accuracy, and performance.
As industrial manufacturers strive to enhance production efficiency by increasing speed, precision, and system reliability, the demand for advanced position feedback sensors has grown significantly. In response, Renishaw has introduced an upgraded version of the RGH24 grating readhead, designed to meet the evolving needs of modern manufacturing equipment.
This new model retains the same compact design and physical structure as the original RGH24, allowing for direct replacement without requiring any modifications to existing systems. Internally, however, it features enhanced electronics, including faster interpolation processors and improved circuitry that supports higher data transfer rates and greater clocking flexibility. These upgrades enable the readhead to operate at higher speeds while maintaining high resolution and accuracy.
Performance improvements include faster operation at resolutions as fine as 0.1 micrometers, with speeds reaching up to 3 meters per second. The system also offers lower cycle error and options for 0.1 μm or 0.2 μm resolution, making it ideal for precision applications. Additionally, the RGS gold-plated scale and digital RS422 output format remain consistent with the standard RGH24 model.
The updated RGH24 encoder system delivers all the advantages of its predecessor—such as non-contact operation, zero friction, and long-term reliability—while offering enhanced speed, resolution, and accuracy. This makes it a preferred choice for demanding industrial environments.
**Introduction to RGH24**
The RGH24 encoder is known for its compact readhead design, which includes built-in subdivision circuitry and provides both digital and analog outputs. Its non-contact design ensures high-speed, maintenance-free operation, making it ideal for use in harsh or high-vibration environments.
The RGH24 series has proven to be highly versatile, capable of handling even the most challenging applications where other open gratings may struggle. Many leading OEMs in the linear motion systems industry have integrated this technology into their products, spanning sectors such as metrology, machine tools, electronics, semiconductors, and flat panel displays.
The readhead also features an LED mounting indicator, a unique optical filtering system that resists dirt accumulation, and a built-in subdivision circuit that can resolve down to 10 nanometers. With its combination of reliability, performance, and value, the RGH24 remains one of Renishaw’s top-selling encoder systems.

Right Angle Prism
Right-angle prism is the most common type of prisms. It is used to re-direct a beam of light at 90 degrees from the the incident direction or used as a 180 beam retro-reflector. They are often coated with various optical coatings to form cubic beam splitters and color separation cubes used in various projection systems.
