Brightness in (de)lux(e) ...

is measured by this sensor. It determines the momentary degree of illumination intensity. The highly sensitive photodiode reacts quickly to the prevailing circumstances, to half-light as well as to spot light. The device (16321) is especially adequate for use outside and has a very robust housing and connecting ports.

  • weather resistant aluminum die-cast housing IP 65
  • integrated transmitter
  • easy mounting and adjustment by three-point plate and built-in box level
  • standard unit: Lux = lx - 100 Lux equal 1 W/m2 or 9.29 foot candle
  • analogous signal output
  • factory test certificate included (DIN EN 10204)
