High performance in compact and light weight of handy size, 44 x 84 x 130.3mm!
Long distance, 100m and 200m!
400m type is also available in the same size!
Long distance Optical Data Transmission Device with serial interfaces. Sophisticated functions are available even with the compact size and light weight. The long distance transmission is enabled by our own data signal processing technologies. Transmission speed: up to 19.2kbps Interface: RS-232C/422 and Current loop/RS-232C etc.
-> Actual transmission distance is 2 times or more than rated value and data transmission with high reliability is realized. -> Many kinds of interface are lined up, RS-232C, RS-422, current-loop and RS-422/RS-485 multi-drop, etc. -> Level lowering warning output is provided due to prevent some troubles such as dislocation of optical axis or dirty lens surface. -> It can be easy to check optical axis adjustment with optical checker or checking terminal.
