Loop detectors can be a great addition to any automatic gate or barrier systems. They give you the option to automatically open the gate/barrier as the car approaches the exit/entrance. As this is an inductive sensor it will only be triggered by vehicles and not pedestrians making it a great for security and convenience. Please note if buying for a new installation you will need the relay base.
The inductive loop detector is designed for parking and access control applications. The detector is connected to an inductive loop that has been cut into the road surface. When vehicles pass over the loop the detector switches on an output. The use of microprocessor and surface mount technology enables a large number of functions to be incorporated into a small package.
