PD 132 Loop Detector 12V for Gate Barrier in UAEPD-132 Vehicle Loop Detector for Gate BarrierVehicle Loop Detector for gateModel No : PD-132PD-132 Inductive Vehicle Single Loop Detectorfor Automatic Gate opener barrier gate Traffic Inductive Vehicle accessThe detector must be installed in a convenient weatherproof location as close to the loop as possible.Installation location must choose to stay away from the heat source,it around other devices must maintain a distance of at least 10mm (mustn’t fix cling to the cabinet).A correct loop configuration and detector installationwill ensure a successful inductive loop detection system.Loop of several important parameters include: loop figure, size,and turns, install methods (details as Loop installation guide ).Specifications:Supply voltage : 12V DCOperating temperature : -20℃ ~ 65℃Storage temperature : -40℃ ~ 85℃Frequency range : 20 KHz ~ 170 KHzReaction time : 10msSignal holding time : Unlimited / limited when loop is permanently covered 10 minutesSensitivity : Adjustable in 4 incrementsLoop inductance : Total loop plus connection wiring: 50μH to 1000μH. Ideal is 100μH to 300μHLoop connection wiring : Maximum length 20 meters, twisted at least 20 times per meterSize of Housing : L78 x W40 x H108mm
