LED55C Infrared Emitter Diode 940nm TO46 (LED55C IR Diode)
The LED55C is an infrared emitting diode, not a photodiode. It is designed using GaAs technology to emit infrared light at a peak wavelength of around 940nm. This makes it ideal for use with phototransistors and photodiodes in optical sensing and communication systems.
It is commonly paired with photodetectors in opto interrupters and reflective sensors, where it acts as the IR light source while another component detects the reflected or interrupted light. The device is housed in a TO-46 metal can package, ensuring durability and precise optical alignment.
