Overview
The OPI1280-080 is a single-channel optical interrupter featuring a side-looking configuration. It utilizes an NPN phototransistor output with an isolation voltage of 15,000 Vrms. The device operates with a forward current of 20 mA and supports through-hole mounting. Key electrical parameters include a maximum collector-emitter voltage of 30 V and a power dissipation rating of 100 mW. The unit functions within a temperature range of -40°C to +85°C.
Feature Summary
- Side-looking optical interrupter design for slot detection
- High isolation voltage capability for safety-critical circuits
- NPN phototransistor output for digital switching applications
Applications
- Industrial position sensing
- Encoder wheel detection
- Safety interlock switches
Procurement Notes
Verify the specific suffix code against official TT Electronics documentation to confirm exact mechanical dimensions and lead frame plating specifications. Ensure the procurement channel provides valid manufacturer traceability records. Confirm that the delivered components match the stated operating temperature range and isolation ratings required by the final system design before integration.
Selection Notes
Select this component when a side-view optical interruption mechanism is required rather than a standard top-down or through-beam configuration. The high isolation voltage makes it suitable for environments requiring significant potential difference between input and output circuits. Verify that the through-hole package style aligns with the printed circuit board layout constraints.
Part Context
This part belongs to the Optek line of optoelectronic sensors manufactured by TT Electronics. The product family focuses on reliable optical interruption solutions for industrial and commercial automation. These devices are designed to provide consistent signal transmission in demanding operational environments.
Replacement Considerations
Consult official substitution guides for compatible alternatives. Generic replacements may differ in physical footprint or electrical characteristics such as current transfer ratio.
