OPI1270-040

Overview

The OPI1270-040 is an axial fiber optic isolator manufactured by TT Electronics/Optek Technology. It consists of a visible red LED emitter and a phototransistor sensor housed in separate opaque molded plastic enclosures, coupled via a plastic fiber optic cable. The device provides high voltage isolation between input and output circuits. Key electrical parameters include a maximum collector-emitter voltage of 30 V, a maximum DC forward current of 50 mA, and a maximum collector current of 25 mA. The operating temperature range is specified from -40°C to +85°C.

Feature Summary

Opaque plastic housings shield the optical signal from dust and contaminants
High noise immunity due to electrical isolation via fiber optic transmission
Visible red LED indicator allows for visual status verification

Applications

Industrial equipment requiring high voltage isolation
Medical equipment demanding electrical safety isolation
Office equipment operating in electrically noisy environments

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm cable length and connector configuration. Ensure that the opaque housing requirements align with the installation environment's contamination levels. Confirm RoHS compliance status through the latest datasheet revision notes prior to procurement.

Selection Notes

Select this component when galvanic isolation is required between control and sensing circuits in dusty or electrically noisy settings. The separate housing design allows for non-in-line mounting configurations. Consider the visible red LED feature if visual alignment or status indication is necessary during installation or maintenance.

Part Context

This part belongs to the OPI1270 series of fiber optic isolators designed for robust industrial applications. The series utilizes plastic fiber optic technology to replace traditional copper wiring where electrical isolation and noise immunity are critical. It serves as a reliable solution for harsh environments where standard electronic sensors might fail due to interference or contamination.
