VCNL4040M3OE-H3 is an integrated I2C proximity and ambient-light sensor with a 940 nm IR emitter, programmable thresholds, and interrupt output.

Best for

  • Combined ambient-light and proximity sensing
  • Low-pin-count I2C sensor interfaces
  • Handheld and notebook optical sensing

Avoid if

  • A discrete emitter and receiver optical geometry is required
  • The enclosure cannot accommodate a 3.25 mm component height

Check before use

  • Validate proximity thresholds with the final cover lens and target objects.
  • Confirm IRED current and duty ratio meet the power budget.
  • Review interrupt behavior and persistence settings.
