Some FC-51 clones drive the IR LED at higher-than-spec continuous current to increase range. Instead of 20 mA, they might push 40–60 mA, heating both the LED and the LM393.

✅ The LM393 can run up to 125°C junction temp, but the plastic case and nearby components degrade faster above 80°C. Some FC-51 clones drive the IR LED at
After taking these precautions, John restarted the robot and monitored the FC-51 IR sensor's temperature. To his relief, the sensor temperature stabilized within the recommended range, and the robot continued to operate smoothly. ✅ The LM393 can run up to 125°C
The module features a 3-pin header for easy connection to microcontrollers like Arduino or Raspberry Pi. Power input (3V – 5V). GND: Ground. OUT: Digital output interface. Key Features & Components
