Request InfoHeidenhain CorporationSCHAUMBURG, Ill., May 17, 2012 — With a flat design, no integral bearing and a very small scanning head, Heidenhain Corp.’s ERO 6000 angle encoder is suitable for use in many metrology systems, in compact rotary tables and in high-dynamic applications such as air-bearing spindles, laser trackers and robot arms. The compact scaning head is made possible by a divergent scanning principle that does not require lenses or other beam-directing optics. The scale graduation is a sturdy, high-quality Metallur graduation and is adhered to a steel hub. The component’s resulting grating period is 20 µm,...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 9/14/2022Digital ReadoutThe ACU-RITE DRO203Q metrology-focused digital readout from Heidenhain GmbH uses DRO203 hardware to integrate geometric metrology functions from the QUADRA-CHEK series.
