OPI1270-026

Overview

The OPI1270-026 is an axial fiber optic isolator manufactured by TT Electronics/Optek Technology. It integrates a visible red LED emitter and a phototransistor sensor housed in separate opaque plastic enclosures, coupled via a plastic fiber optic cable. The device provides high-voltage isolation between input and output circuits while maintaining electrical independence. Key specifications include a lead spacing of 0.05 inches (1.27 mm) and operation within industrial temperature ranges. The design ensures high noise immunity and shields the optical signal from environmental contaminants.

Feature Summary

Opaque plastic housings shield the optical signal from dust and contaminants
High voltage isolation between input and output circuits
Visible red LED with phototransistor output for clear status indication
Flexible installation due to non-optical alignment requirements between emitter and sensor

Applications

Industrial equipment requiring high voltage isolation
Medical equipment demanding electrical safety
Office equipment with dirty environment exposure
Applications requiring electrical isolation in contaminated environments

Procurement Notes

Verify the specific cable length associated with the -026 suffix against official datasheets, as this determines the physical separation distance between the emitter and sensor units. Confirm that the opaque housing material meets the required environmental protection standards for the intended deployment location. Ensure compatibility with existing mounting hardware given the 0.05-inch lead spacing.

Selection Notes

Select this component when physical separation of control and sensing circuits is necessary without electrical connection. The visible red LED aids in visual system verification during installation. Consider the fiber optic coupling efficiency and potential signal attenuation over the specified cable length. Evaluate the need for high noise immunity in electrically noisy industrial settings where traditional electrical isolators might fail.

Part Context

The OPI1270 series represents Optek's solution for robust fiber optic isolation. These devices replace traditional electrical connections in harsh environments. The series utilizes plastic fiber optics for cost-effective, flexible installation. The OPI1270-026 variant offers specific cable length characteristics suitable for standard industrial panel layouts.
