Single Channel Loop Detector for Parking Barrier Gate Truck Motorcycle Forklift

 

Overview

The Single Channel Loop Detector from JUTAI is a vehicle presence and pulse detection device designed for use with inductive loops installed in the ground. It is suitable for detecting the presence of vehicles such as cars, trucks, motorcycles, and forklifts. This makes it ideal for a wide range of applications including parking barrier gates, industrial doors, toll systems, access control, and traffic management.

The detector provides both presence and pulse detection modes through its two relay outputs. It features adjustable sensitivity, multiple operating configurations, and stable performance for both indoor and outdoor use when installed properly.

Vehicle Compatibility

The loop detector is capable of detecting various types of vehicles including:

 

 

• Passenger vehicles

 

• Trucks (light and heavy duty)

 

• Motorcycles

 

• Forklifts

• Other metal vehicles with sufficient size and mass

Proper loop installation is required to ensure accurate detection for each vehicle type.

Detection Modes

 

 

• ​Presence Mode:​​ The detector provides a continuous signal when a vehicle is detected above the loop. This is useful for applications such as parking space occupancy detection or holding a gate open.

• ​Pulse Mode:​​ The detector provides a momentary signal when a vehicle passes over or reaches the loop. This is commonly used to trigger a gate to open or to count vehicles.

---

Adjustable Settings

 

 

• ​Sensitivity:​​ Adjustable via a built-in control knob with multiple sensitivity levels to match different loop configurations and vehicle types

 

• ​Relay Timing:​​ Delay time can be set through DIP switch settings to control how long the relay remains active after detection

 

• ​Operating Mode:​​ Choose between presence hold, auto-reset, test mode, and other configurations to suit your application

• ​Frequency Selection:​​ Different frequency options help avoid interference when multiple detectors are used nearby

For proper operation all DIP switch changes must be followed by pressing the reset button on the device.

Loop Installation Information

The loop detector works with inductive loops that are installed in the ground. These loops are typically made using insulated wire installed in a rectangular or circular shape cut into the road surface and connected to the detector.

Common loop sizes and the recommended number of wire turns:

 

 

• Loops with perimeter between 3 and 4 meters: 6 turns

 

• Loops with perimeter between 4 and 6 meters: 5 turns

 

• Loops with perimeter between 6 and 10 meters: 4 turns

 

• Loops with perimeter between 10 and 20 meters: 3 turns

• Loops over 20 meters: 2 turns

Loops should be installed using a suitable resin or asphalt material to secure the wire in place. The loop wires connect to the detector using standard two-core cable. For longer distances a shielded two-core cable is recommended.

Power Options

 

 

• Model LD-100: 100-240V AC power input

• Model LD-102: 12-24V DC power input

Choose the model that matches your system’s power supply for reliable operation.
