An induction or inductive loop is an electromagnetic communication or detection system which uses a moving magnet or an alternating current to induce an electric current in a nearby wire.

Vehicle detection loops, called inductive-loop traffic detectors, can detect vehicles passing or arriving at a certain point, for instance approaching a traffic light or in motorway traffic. An insulated, electrically conducting loop is installed in the pavement.

Vehicle Loop Detectors. An inductive loop detector is used to detect motor vehicles. When the motor vehicle drives over the detectors wire loop the detectors senses the metal and then a relay is activated. This relay is connected to the motor controller card to automatically open the gate or door.

Vehicle Loop detectors are used to detect the presence of vehicles to open a barrier. Basically an inductive loop detector system consists of three components: a detector, a loop and loop extension cable. Typically the loop is connected to a loop detector.

Vehicle detectors sense the presence of vehicles. They provide an output signal to a control unit, such as a gate or door operator, to open or close. When used as a safety device, vehicle detectors prevent a gate or door from closing on a vehicle.

JUTAI Industries provides a variety of vehicle loop detector products and assorted accessories for a range of applications. Let’s take a look at some of the key features of our inductive loop detectors.

• Compact Size: the compact and well engineered housing     

• Combines all of the industry requirements regarding          

• Features and functionality and allows this detector to be Incorporated into any or existing traffic detection system.     

• Diagnostic Capabilities: Comprehensive diagnostics                 

• Capabilities allow for accurate diagnosis of loop and Installation problems.

• Selectable Presence Time: The output of the presence Relay can be selected to limit a detect output to a fixed time(time>30 minutes)while a vehicle remains on the loop

• Loop Frequency Indication: Interference between adjacent loop/detectors can be determined by an integral indication, and eliminated by changing the frequency setting.

• Two separate output relays: Presence Relay A is presence output. Can be extended for 0,2,5,8,10,15,20 or 30 seconds, programmable with external 10 way DIP switches.Pulse Relay B, programmable with external 10 way DIP switches, provides presence, pulse on entry, pulse on exit, or failed output.
