Overview
The OPI1280-018 is a fiber optic isolator featuring a visible red LED coupled to a phototransistor sensor via plastic optical fiber. Designed for through-hole mounting, it provides electrical isolation in harsh environments. The device utilizes opaque molded plastic housings to shield the optical signal from dust and contaminants. It offers high noise immunity and includes a 0.100-inch lead spacing configuration suitable for standard PCB layouts.
Feature Summary
- Opaque plastic housings provide shielding against dust and environmental contaminants
- High noise immunity ensures reliable signal transmission in electrically noisy settings
- Visible red LED allows for visual verification of the optical link status
Applications
- High voltage isolation between input and output circuits
- Electrical isolation in dirty or dusty industrial environments
- Medical equipment requiring robust signal integrity
Procurement Notes
Verify the specific suffix (018) confirms the required cable length and lead spacing during procurement. Confirm that the opaque housing design meets the environmental protection requirements of the target application. Ensure compatibility with through-hole assembly processes and verify insulation voltage ratings against system safety standards before finalizing orders.
Selection Notes
Select this component when physical separation between transmitter and receiver is necessary due to space constraints or interference issues. It is suitable for applications where electromagnetic interference would compromise standard optocouplers. Consider the visible red LED feature if visual alignment or link status indication is beneficial during installation or maintenance.
Part Context
This part belongs to the OPI1280 series of fiber optic isolators manufactured by TT Electronics/Optek Technology. The series includes variants with different cable lengths, such as the OPI1280-032. These devices are engineered to replace traditional optocouplers in scenarios requiring enhanced durability and isolation capabilities.
Replacement Considerations
Direct replacements include other OPI1280 series variants like the OPI1280-032, which differ primarily in cable length. Verify that alternative fiber optic isolators maintain comparable insulation voltage ratings and lead spacing dimensions to ensure mechanical and electrical compatibility.
