Red Barrier series Photoelectric Beam Detectors


Dual beam, high cost performance detector

Range : Outdoor 30m / 60m / 90m,
Indoor 60m / 120m / 180m

  • Dual beams : Offers stable operation without false and miss alarms.

  • Newly designed spherical fresnel lens : Makes the very sharp beam ray and contributes to achieve the high performance features.

  • Easy optical alignment : 3 methods are adopted. For rough alignment : Scope, and for precise alignment : LED and Volt meter.

  • IP55 : Protect the inside of the detector from rain, snow, dust, sand and other objects which comes inside.

  • Unique knockout structure : Allows the surface wiring keeping IP55.

  • AGC (Auto gain control) : Control NRTS by following the various circumstance.

  • 100 times sensitivity : Stable operation is maintained even if 99% beam power is lost.

Selection Tips
