Luminescence sensors

Compact sensor for long sensing distances

Your Benefits

  • Robust metal housing is reliable and ideal for tough environment conditions
  • High detection reliability ensures the process: Blue transmitter LED excites red luminophores especially well. The UV LED is well-suited for blue, green or yellow marks.
  • Visible light spot of the LUT1B version makes accurate alignment easy


Compact sensor for long sensing distances

LUT1 series luminescence sensors feature easy to adjust sensitivity. The switching threshold can be adjusted via a plus/minus button, greatly simplifying setup for applications that require changeover. Even at very high speeds, luminescent marks are reliably detected. The visible blue emitted light from the LUT1B version is well-suited for red luminescent marks.

At a glance
  • Infinite switching threshold adjustment via membrane keyboard
  • Long sensing distances up to 150 mm
  • Sender LED UV (375 nm) or blue (470 nm)
  • Switching frequency 600 Hz or 6 kHz
