OPI1270-018

Overview

The OPI1270-018 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 design provides high voltage isolation between input and output circuits while shielding the optical signal from dust contamination. Key physical specifications include a lead spacing of 0.05 inches (1.27 mm). This configuration allows for data transfer through the fiber optic medium without requiring the emitter to be optically in-line with the sensor, depending on cable length.

Feature Summary

Opaque plastic housings shield the optical signal from environmental contaminants such as dust.
Provides high noise immunity and electrical isolation between input and output circuits.
Visible red LED indicator paired with a phototransistor output for clear status indication.

Applications

Industrial equipment requiring high voltage isolation
Medical equipment operating in electrically noisy environments
Office equipment needing reliable signal transmission

Procurement Notes

Verify the specific part number suffix against official TT Electronics/Optek Technology documentation to confirm cable length and connector type. Ensure compatibility with existing system voltage requirements and isolation standards before procurement. Cross-reference datasheets for any recent product change notices or obsolescence alerts associated with this component series.

Selection Notes

Select this component when high voltage isolation is required in dusty or electrically noisy environments. The opaque housing design makes it suitable for applications where background radiation interference must be minimized. Consider the physical separation distance allowed by the fiber optic cable length when designing the enclosure layout.

Part Context

This component belongs to the OPI1270 series of fiber optic isolators from TT Electronics/Optek Technology. The series is designed for robust performance in harsh industrial conditions. The specific model utilizes a visible red LED for easy visual alignment verification during installation.
