Industrial Sensors / KL(R)50 Series

KL(R)50 Series


The KL(R)50 Series sensors are through-beam type CMDs that output signals when detecting blockage of light as the detected object passes between the transmitter and receiver.  Two different output models are available, choose between relay output or voltage (10VDC quasi TTL) output types .

  • Compact, low-cost: the smallest size and lowest cost of all water-cooled CMD sensors.
  • Robust and lightweight case is capable of withstanding severe operating conditions such as heat, water and shock.
  • Excellent stability. Emitted optical output is about tenfold of required operation level at detecting distance of 50 m; which ensures detection even with minor soiling of lens in an adverse environment.
  • Attachable airless dust hood or air purged hood, to prevent/minimize of soiling of lens, etc.
