IF389 Temperature Sensor – Reliable Thermal Protection for TFT Displays

The IF389 temperature sensor is designed to monitor the permissible operating temperature of your TFT display system, offering intelligent protection in extreme environmental conditions.

When connected to a compatible TFT controller, the IF389 enables automated thermal responses. If the temperature exceeds or falls below the defined limits, the system can:

  • Switch off the display to prevent thermal damage

  • Activate a fan or heater to regulate internal conditions

This proactive temperature management ensures longer system lifespan, increased operational reliability, and safe usage in demanding environments such as outdoor kiosks, industrial automation, or transport infrastructure.

Key Benefits:

  •  Real-time monitoring of operating temperature 
  •  Protects display from overheating or frost damage 
  •  Automates fan or heater control via TFT controller 
  •  Prevents damage and extends display lifespan Ideal for industrial, outdoor, and mission-critical applications
