OPI1270-032

Overview

The OPI1270-032 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 molded plastic enclosures, coupled via a plastic fiber optic cable. This configuration provides high voltage isolation between input and output circuits while shielding the optical signal from environmental contaminants such as dust. The device features a lead spacing of 0.05 inches (1.27 mm) and enables data transfer through the fiber link without requiring optical alignment between the emitter and sensor.

Feature Summary

Opaque plastic housings shield the optical signal from dust and contamination
High noise immunity for reliable operation in electrically noisy environments
Visible red LED with phototransistor output for clear status indication
Flexible installation allows non-aligned positioning of emitter and sensor

Applications

Applications requiring high voltage isolation between input and output
Electrical isolation in dirty or dusty industrial environments
Industrial equipment control systems
Medical equipment safety circuits
Office equipment sensing interfaces

Procurement Notes

Verify the specific cable length associated with the -032 suffix against official TT Electronics documentation to ensure it matches system requirements. Confirm that the opaque housing material and lead spacing meet mechanical constraints. Check current product lifecycle status as component availability may vary. Ensure compatibility with operating temperature ranges specified in the datasheet for the intended environment.

Selection Notes

Select this component when electrical isolation is required across physically separated points without direct conductive paths. The opaque housing makes it suitable for harsh environments where standard open-beam sensors would fail due to particulate interference. Consider the fixed lead spacing and fiber coupling method during PCB layout and mechanical design phases to ensure proper fit and function within the assembly.

Part Context

The OPI1270 series belongs to TT Electronics/Optek Technology's portfolio of fiber optic isolators designed for robust performance in challenging conditions. These devices utilize plastic fiber optic technology to transmit signals between isolated zones, offering an alternative to traditional optocouplers where physical separation or superior noise immunity is critical. The series supports various applications demanding reliable signal transmission in the presence of electromagnetic interference or environmental hazards.
