The PB-IN-HF series is the flagship of the TAKEX range of infrared photoelectric beams. By synchronizing 16 beam paths between Transmitter and Receiver, the PB-IN-HF series offer unrivaled stability in perimeter security. Coupled with channel separation and environmental (anti-fog) circuitry, the PB-IN-HF series has earned worldwide recognition as the standard our rivals aspire to.

For distances up to 50m (165ft) outdoor / 100m (330ft) indoor.


  • 4 Synchronised High-Power Beams
  • Selectable 4-Channel Beam Frequencies
  • Double Modulated Beam for unsurpassed Light Immunity
  • Monitor Jack for alignment with Multi-Meter
  • Audible Alignment Tone
  • Environmental (anti-fog) Monitoring Circuit
  • Dynamic A.G.C. Circuit
  • Frost Resistant Cover
