USB accessories for optical sensors 29.10.2013 Whether a lab PC or company laptop – even computers without the RS422 industrial interface can now evaluate readings from laser and confocal sensors from Micro-Epsilon. A 4-channel RS422/USB converter is now available for this purpose. Micro-Epsilon introduces the 4x RS422/USB converter. The IF2004/USB converts digital signals from up to 4 optical sensors into a USB data packet. The converter is suitable for laser triangulation and confocal-chromatic displacement sensors from Micro-Epsilon. Unlike other commercially available USB hubs, the new converter ensures synchronous data acquisition for a defined temporal allocation of the four RS422 inputs. This is particularly important for small system solutions with multiple sensors, for example, in thickness measurements. The new converter has 4 trigger inputs and a trigger output for connecting additional converters. The connected sensors and the converter can be programmed through software.
