Click on the dots in the image above to find out more about RESOLUTE™Unique single-track absolute scale
IP64 sealed bodyTough machined aluminium body is sealed to IP64 to resist ingress of oil, coolant or water. If a seal fails on axis and the readhead is splashed with liquid, simply drain the enclosure and replace the seal, wipe the readhead and scale, then start work again. Set-up LED on the readhead
Rugged and reliable serial communicationsAll processing and interpolation electronics are contained inside the readhead, meaning that the only signals going through cables are digital differential signals in serial communications format. Noise rejection is excellent and furthermore, CRC checks are carried out inside the readhead and controller to ensure the serial word has been transmitted correctly. High-flex, double-screened cableDesigned to meet the demands of high-speed linear motor axes, RESOLUTE is fitted with a cable that achieves more than 20 million flex cycles and also incorporates double shielding for superior noise immunity. The cable is equally well suited to rotary axes where it is held in a fixed position. UL approved. Variety of serial communications protocols
Advanced optical detection scheme
Think of RESOLUTE as an ultra-fast miniature digital camera, taking photos of a scale that consists of a long, non-repeating bar code. RESOLUTE analyses these photos to determine position to resolutions as small as 1 nanometre with remarkable low noise (jitter) and SDE. This provides smoother velocity control and rock-solid positional stability. RESOLUTE high accuracy absolute linear and angle (rotary) scale options
Linear scales:
Angle (rotary) scales:
Built-in position-checking algorithmRESOLUTE features a built-in separate and independent position checking algorithm. This actively checks every reading, ensuring any potential problem is flagged long before it reaches the controller. High dirt immunityRESOLUTE uses a state-of-the-art DSP (Digital Signal Processor) to analyse and decipher the code redundancy and cross-checking. Combined with advanced optics, the effects of dirt and contamination are significantly rejected.
WEEE and RoHS complianceRESOLUTE satisfies the highest environmental standards, with both WEEE and RoHS compliance. As with all Renishaw encoders, RESOLUTE is backed by a truly responsive global sales and support network. More about RESOLUTE... | | Data sheetsInstallation guides

RESOLUTE features a single track, optical absolute scale, combining both the absolute position and embedded phase information into one single code. This technology provides RESOLUTE with far wider set-up tolerances for quick and easy installation and superior long-term reliability.
Please note that only RTLA scales feature a line that indicates orientation of the scale; holding the scale horizontally in front of you, when the orientation line is above the coded graduations, the lowest position value is on the left-hand end of the scale. The orientation line is not seen by the readhead and is not a second track. Therefore the readhead/scale system maintains the benefits of being a single-track system.
Completely intuitive and easy to use, RESOLUTE features an integral set-up LED for simple adjustment and fault-finding, eliminating the need for additional diagnostic tools and reducing the chance of human error.
RESOLUTE is available with a variety of serial protocols for connection to a wide range of industry-standard controllers. Contact Renishaw for the latest list.
