SIR-568ST3F

SIR-568ST3F Sensors Infrared light emitting diode, top view type SIR-568ST3F The SIR-568ST3F has the response speed and luminous output necessary for image transmission in audio-visual applications. It can support almost all types of optical transmission through air, including audio and data transmission. The luminous output is 13mW and the cutoff frequency is 50MHz. 2 1 (2.5) φ6±0.3 2.5±1 Features 1) High luminous output 13mW. 2) Fast response is possible 50MHz cutoff frequency. Min.24 2− 0.5 Max.1 4−0.6 1 8.7±0.3 Applications Transmission of images from a video cassette recorder to a television. Transmission of audio signals between audio devices. High speed data transmission. Dimensions (Unit : mm) φ5.0±0.2 Notes: 1. Unspecified tolerance shall be ±0.2 . 2.
