Sell 100 meters Twin-Beam Infrared Photobeam Sensor with 8 channel frequency ( FREE COURIER & GIFT ) best price

(( FREE COURIER to WEST Malaysia & EAST Malaysia with FREE GIFT )) Twin-Beam Infrared Photobeam Sensor with 8 channel frequency 100m Outdoor Alarm Photobeam Sensor Dual-Beam Double-Beam Photoelectric Sensor; comes in a pair of RX and TX 100m Outdoor Distance; 300m Indoor Distance Simultaneous interruption of 2 infrared beams Digital Infrared Pulse, Response Time 12 - 250ms; Operating Voltage 12-24VDC When intruders enter and run across the infrared beams, alarm relay on the receiver gives reaction of output; this detector adopts simultaneous-block-alarm mode: only when the upper and lower 2 beams are blocked at the same time, alarm relay can detect and make an output, in this way, it can avoid false alarm caused by small animals, falling leaves, birds etc. Product characteristics: 1. Its 2 beams are with simultaneous and effective operation and it is fit for outdoor installation and usage with powerful function of anti-fog, snow and rainstorm. 2. 8 wave band frequencies for option. It can clear away or avoid beams interference caused by highly infrared beams overlapped and long-distanced detection. 3. The receiver is with digital 10 groups of LED indication, so its beams axis can be adjusted quickly and accurately even without multi-meter focusing the pressure. 4. The receiver adopts intelligent CPU design and quartz oscillator. Its frequency is stable and won't be affected by temperature or humidity change. 5. Its receiver adopts intelligent CPU design, decoding circuit, AGC circuit, digital wave band filtering circuit and alarm output control circuit are all processed by CPU software. The accurate action can increase signal recog- nition ability greatly and avoid external interference. 6. Adopts unique plane Fresnel lens to get more powerful optical focusing to avoid false alarm effectively.
