Background Suppression Photodiode

Technical Excellence
To ensure stable performance in automation, our Background Suppression Photodiode features a wide spectral response range (350nm – 1060nm) with peak sensitivity at 800nm. The device maintains a low dark current profile, ensuring that signal detection remains accurate even in fluctuating lighting conditions. Its robust plastic package is compatible with lead-free reflow soldering, making it easy to integrate into modern SMT production lines.

Usage Scenarios

  • Production Line Sensors: Detects objects on conveyor belts while ignoring the belt surface itself.
  • Limit Switches: Provides precise end-stop detection in robotics.
  • Proximity Detection: Ideal for short-range sensing where background noise is a critical issue.
