What is SiGNUM?
SiGNUM is Renishaw’s high accuracy, non-contact 20 µm incremental encoder system comprising of an Sr readhead and Si interface. It is sealed to IP64 and offers speeds up to 12.5 m/s and resolutions down to 5 nm, and reads a variety of linear and rotary scales with IN-TRAC auto-phase optical reference marks. SiGNUM is extremely easy to use with calibration at the push of a button and free diagnostic software, yet it offers a level of performance previously available only from more delicate fine pitch encoders with an SDE of typically <±30 nm at temperatures up to +85 °C.
