This is Alarm Two Beam Photoelectric Infrared Detector. Integrated design, installation brackets, the most convenient installation. Holographic spot real-time report. Unique displacing receiving, transmitting parts with big power. Full function checking, self-adaption in environment and trouble locking. Patented balanced checking, unique digital filtering.Safety Photo Beams For Gate Openers- The Aleko photo eyes are a valuable safety feature that will keep the gate from closing when any obstruction is in the path of the photoelectric beam.- The photo eyes use Dual Beam and Through Beam technology, which are more reliable than reflective beams because they do not allow sunlight to create a false reading- The photo eyes need to be direct wired into the gate opener's circuit board with low voltage wire. We recommend using 16 gauge, multi-stranded, dual conductor, low voltage wire for all gate opener installations.FeaturesAnti-glare up to 50,000 LUX, built-in automatic adjustment strong light filtering system, avoid glare or lighting of carUnique optical design: optical glass, beam penetrates the special multi-layer anti-environment (such as rain and snow) and other capabilitiesAutomatically increase sensitivity when faced with fog or inclement weatherOptional dual aspheric fresnel or secondary focusing lens to achieve a large-diameter light beamAutomatic environment recognition circuit (EDC), avoid reflective interference modularHorizontal / vertical optical angle easy to adjust, easy to calibrateHigh levels of resistance to RFI / EMI capabilityUnique digital filter circuit design99% photographic marginBuilt-in optical sightAnti-lightning circuit designUse of C-type output deviceAdjustable beam interdiction cycle is more flexible and adaptableThe integrated structure designed to be able to work in harsh environmentSpecificationsRange30m / 100ftNo.of Beams2 beamsDetection Mode2 beams blocked simultaneousOptical SourceInfrared digital pulse beamResponse Speed50 ~ 700msecRelay Contact OutputNO.NCContact RatingAC/DC30V 0.5AMaxPower SupplyDC 13.8 ~ 24V AC 11 ~ 18V P ≥15WOperation Temperature-25℃ - 55℃Operation Humidity5% - 95% RH (relative humidity)Dimension8 x 7.6 x 16.1cm/3.15 x 2.99 x 6.34"(L x W x H)ColorBlackProduct Weight29.42 ozPackage Includes2x Alarm Two Beam Photoelectric Infrared Detector1 x Installation Accessories with Hardware2 x Manual,RcmdId ViewItemDescV4,RlogId p4%60bo7%60jtb9%3Fuk.rp*05e54c%3E-1594f2b6436-0x10c-->
