Overview
The OPI1290-040 is a side-looking optical interrupter from TT Electronics/Optek Technology, featuring PhotoLogic logic output. It operates with DC input and provides push-pull, totem pole output signals. The component exhibits a maximum propagation delay of 5µs for both low-to-high and high-to-low transitions. Typical rise and fall times are specified at 25ns each, ensuring rapid signal response for digital interfacing applications.
Feature Summary
- Side-looking geometry designed for slot-based detection
- Integrated PhotoLogic circuitry for direct digital output
- Push-pull totem pole output stage for robust signal driving
Applications
- Industrial position sensing
- Encoder wheel detection
- Automated machinery limit switching
Procurement Notes
Verify the specific datasheet revision when ordering, as TT Electronics issues product change notifications for the OPI1290 series. Confirm mechanical slot dimensions match your application design. Check current availability status, as some distributors may list this part as obsolete or not available online. Ensure RoHS compliance requirements align with your manufacturing standards.
Selection Notes
Select this model when a compact, side-emitting solution is required for precise slot alignment. The integrated logic output eliminates the need for external comparators, simplifying PCB layout. Consider the 5µs propagation delay for timing-critical systems. Verify that the operating environment does not exceed the component's thermal limits.
Part Context
This device belongs to the Optek PhotoLogic family, which integrates infrared emission and detection with on-board signal processing. The series is engineered for high reliability in industrial and aerospace environments. TT Electronics supports these components with screening options per MIL-STD-750 and MIL-PRF-38535 standards for critical applications.
Replacement Considerations
Consult official substitution guides for compatible alternatives within the OPI1290 series. Verify pinout compatibility and electrical characteristics before replacing. No public substitute part numbers are confirmed in the provided documentation.
