Cold Metal Sensors / KL(R)50 Series

KL(R)50 Series


The KD50 Series HMDs are extremely compact and low- cost for an amplifier-integrated water-cooled sensors. The KD50 Series sensors directly detect infrared radiation and output ON-OFF signals, which is useful for applications such as detection of passage or position of red-hot steel materials including ingots, slabs, steel plates and mold steel.

  • The smallest of water-cooled sensors with built-in amplifiers and enclosed in a robust case that can withstand severe operating conditions.
  • Choose between narrow-view and wide-view types according to your installation requirement.
  • Reasonably priced and streamline in design the KD50 Series are High performance Detectors with the capability to detect steel materials with a temperature as low as 450°C (minimum).
  • Performance comparable to full-size HMDs with a Long detecting distance, sensitivity adjustment feature and high sensitivity which offers excellent stability.
  • Attachable airless dust hoods and air purge hoods prevent the build-up of dirt deposits on the lens.
