Haosie Parking Barriers Opener, Smart Car Detectors, Vehicle Detector System, 4 Frequency Configurations, for Vehicle Access

• Smart Barrier Opener: The intelligent barrier door opener is equipped with a vehicle loop detection function, with a green LED displaying the vehicle detection status and a red power indicator light
• Sensitive Detection: This feature determines the non detection level at maximum sensitivity to avoid detecting large trucks and other vehicles, typically used to prevent false detection of small or fast objects
• 4 Frequencies: The 4 sensitivity settings on the switch can change the sensitivity. Using four frequency configurations to avoid signal interference with adjacent loops is beneficial for maintaining normal road order
• ABS Structure: Made of good ABS material, installation requires maintaining a 10 mm distance from surrounding equipment, automatic diagnostic system alerts loop faults through LED flashing, suitable for outdoor use
• Parking Access Plan: Relays display road conditions and power on status through lighting, achieving automated operation, and can be used for parking lot barriers and traffic management system solutions

When the detector is tuning, the green channel LED and the red power LED will illuminate. It stays for about 2 seconds and then the green LED goes out. If there is a loop failure, the channel LED will illuminate and flash to indicate a fault. If the fault is self-healing, the detector will continue to run. The green channel LED will also illuminate as soon as the vehicle is detected to pass through the inductive loop. The red power LED on the top of the unit will remain lit, indicating that the unit is powered Specifications: Material: ABS Color: Black Reaction time: 10 ms Supply voltage: 220 V Power consumption: 4.5 VA Output relay: 240 V/ 5 A Voltage tolerance DC: ±15% Withstand voltage AC: + 10%/ -15% Operating temperature: -20°C to +65°C Storage temperature: -40°C to +85°C Frequency range: 20 kHz to 170 kHz Sensitivity: adjustable in 4 increments Signal hold time: unlimited /limit cycle for 10 minutes permanently Loop inductance: The total loop plus connection line is 50μH to 1000μH (ideally 100μH to 300μH). Loop connection wiring: Maximum length 20 meters, twisted at least 20 times per meter. Package List: 1 x Barrier Opener 1 x Connection Terminal 1 x Instruction Manual Note: 1.The detector must be installed in a convenient weatherproof position as close as possible to the loop 2.The installation location must be chosen away from the heat source. 3.Other equipment around it must be at least 10 mm away (not to be tightly mounted to the wall) 4.Proper loop configuration and detector installation will ensure a successful inductive loop detection system 5.Several important parameters of the loop include: cycle diagram, size, turn, and installation method 6.Please note that the new type and old type of this product will be sent randomly
