Red Barrier series Photoelectric Beam Detectors


Dual beam detector with 4 frequency selectable.

Selectable frequency 4 channels : Stacking, Straight line, Square or other various applications are allowed.

  • 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.

  • EDC ( Environmental Discrimination circuit ) : Beam reception level is severely dropped in heavy fog, snow and rain, often causes false alarms. EDC signal is output when the beam receiving power down.

  • 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.

Selection Tips

Dual beam detector for stable operation.
4 frequency channels are selectable for stacking, straight line, etc. .
High cost performance comparing with Quad beams for short range application.
