BWF [Serial type / long distance type] - Optical Data Transmission Devices
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!
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.
