The ALS4 and ALS6 optical scales have a 20um optical grating that produces an 11-15uA output signal compatible with many legacy digital readout and older CNC controls.

Unlike all our standard optical and magnetic scales the ALS scales come with a 9-pin round connector directly compatible with these older systems. No need for further adaptor cables.

All GS Series Optical scales are laser calibrated in a controlled environment using the latest Renishaw™ lasers and supplied with a traceable certified certificate of accuracy.


Introduction to Optical Encoders:

All our digital optical encoders conform to EIA422 standards and implement full differential encoder connections and screen cables to ensure the best possible noise immunity. With resolutions as fine as 0.1um and accuracies to 3um they are ideal for a broad range of machine tool and CNC applications. All our scales are ‘bearing’ scales and so always run true on the glass to ensure accuracy and lifetime performance.

In addition to Digital scales 1Vpp and 11uA scales are also available for both 20um and 40um optical grating making them not only ideal for new installations but also for service replacements for older 3rd party systems.


Distance-coded scales in either 1Vpp or EIA422 digital are available with 20um optical grating for machine tool and CNC applications
