BWF[Serial type/long distance type] |
OPTICAL DATA TRANSMISSION DEVICE |
![]() |
High performance in compact and light weight of handy size, 44 x 84 x 130.3mm! |
Feature
- 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.
