Overview

Features

-> 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.
