Parameters and selection points
Package, electrical, optical, and sourcing checks
Optical checks: 850 nm or 940 nm class wavelength, radiant intensity, viewing angle, and lens style.
Electrical checks: forward current, reverse voltage, dark current, response time, and sensitivity.
Mechanical fit: lamp type, SMD package, side-view option, board height, and assembly constraints.
Confirm whether the design needs an IR source, a detector, or a matched emitter-receiver pair.
Match wavelength, radiant intensity, viewing angle, distance target, and optical housing conditions.
Review response speed, dark current, sensitivity, and ambient-light tolerance for sensing designs.
Share sensor distance, enclosure, driver circuit, receiver circuit, and target environment for sampling.
