The Honeywell SD5410-002 is a silicon photodarlington designed for use in a variety of applications requiring sensitive light detection. Encased in a TO-46 metal can package, this device offers a narrow acceptance angle due to its glass lensed design. It's specifically engineered to be mechanically and spectrally matched with Honeywell's SE3450/5450, SE3455/5455, and SE3470/5470 infrared emitting diodes, making it ideal for optical receiver circuits and light-sensing applications in industrial and commercial settings. The device's wide operating temperature range (-55°C to +125°C) ensures reliable performance in challenging environments.
