The JUTAI Dual Channels Traffic Detector (LD-200/202) is engineered for precise vehicle detection and reliable traffic monitoring in parking and access control systems.
Key Features
Dual independent detection channels (CH1 and CH2)
Comprehensive diagnostic indicators for power and loop status
Adjustable sensitivity and frequency via dip switches
Multiple operational modes including direction detection
Use ferromagnetic wires with total length up to 500 meters
Keep product plug and socket in vertical direction during installation
Working Principle
Entry Process
Exit Process
Both loop coils detect vehicle entry
LD-200/202 triggers UHF reader at entrance
UHF reader sends ID to controller (AC-11)
Controller outputs relay signal to open gate barrier
Vehicle enters and barrier lowers automatically
LD-100/102 ensures safety and anti-smashing functionality
Vehicle passes inside UHF reader during exit
LD-200/202 triggers UHF reader to read card ID
Controller verifies ID validity and opens gate barrier
Vehicle exits and barrier lowers automatically
LD-100/102 provides safety and anti-smashing functionality
Direction Recognition
The Direction Recognition Function prevents duplicate triggering when vehicles pass additional UHF readers, ensuring accurate entry/exit record keeping.
System Integration
Compatible with JUTAI door controller (AC-11), gate barrier (BR-110), long-range RFID reader (PUHF-9), and high-temperature resistance loop coils (JTHT-11) for comprehensive access control solutions.
Independent Operation Mode
LD-200/202 can function as two independent single-channel loop detectors, ideal for standard one-in/one-out parking lots while reducing hardware costs.
Troubleshooting Guide
Symptoms
Solution
Detector not working
Press reset button
Red LED indicator not fully lit
Check power supply connection
Green LED blinking slowly
Possible loop short circuit or insufficient turns
Green LED blinking faster
Possible loop open circuit or excessive turns
Insufficient number of turns
Lower frequency (add more turns if frequency still too high)
Excessive number of turns
Higher frequency (remove some turns if frequency still too low)
