# JUTAI LD-202 DC Power Inductive Loop Sensor for ETC Lanes & Highway Toll Collection For toll road operators and ETC (Electronic Toll Collection) system installers, the JUTAI LD-202 DC Power Inductive Loop Sensor is a game-changer. Powered by 12-24V DC, this compact JUTAI detector delivers precise vehicle detection in high-traffic ETC lanes, ensuring seamless toll transactions and reducing traffic backups. Unlike basic loop detectors that struggle with fast-moving vehicles, the JUTAI LD-202 uses anti-interference frequency technology (20KHz–100KHz adjustable) to detect cars, trucks, and buses even at highway speeds. It’s the ideal choice for ETC lanes, toll plazas, and highway road safety systems where accuracy and speed matter most.
- DC Power Flexibility: 12-24V DC input works with solar-powered toll booths or battery backups, making the JUTAI LD-202 suitable for remote highway locations.
- Fast Detection Response: Triggers in milliseconds to sync with ETC readers, ensuring tolls are processed before vehicles pass through the lane.
- Dual-Channel Reliability: Monitor two ETC lanes with one JUTAI detector (CH1 & CH2), cutting down on equipment costs for toll operators.
- Durable for Outdoor Use: Built to withstand highway conditions—dust, rain, and extreme temperatures—so the JUTAI LD-202 maintains performance year-round.
Toll road congestion often happens when detectors miss vehicles or trigger falsely. The JUTAI LD-202 solves this with its high-accuracy sensing: it ignores small debris (like leaves or rocks) and only detects metal vehicles, eliminating false toll charges or missed transactions.
It also integrates easily with ETC systems and traffic control software—simply connect the JUTAI LD-202’s relay contacts (CH1: Pin 10,11; CH2: Pin 7,8) to your existing setup, and you’re ready to go. For toll operators looking to boost efficiency, this DC-powered JUTAI sensor is a must-have.

Application
The JUTAI LD200/202 double-channel vehicle loop detector series, equipped with direction recognition function, is ideal for numerous single-channel entry and exit scenarios. When integrated with the JUTAI One door controller (Model: AC-11), JUTAI gate barrier (Model: BR-110), and JUTAI long-range RFID reader (Model: PUHF-9), along with high-temperature resistance loop coils (Model: JTHT-11), it forms a seamless solution for single-channel entry/exit access control systems.
The working principle is as follows:
-
Entry Process:
- When a car enters the community or parking lot, the two loop coils are pressed simultaneously.
- The JUTAI Double Channel Loop Detector (LD-200/202) triggers the UHF reader located at the entrance.
- The UHF reader reads the card ID and sends it to the controller (AC-11) via Wiegand output.
- The controller verifies the ID's validity and outputs a relay signal to open the gate barrier.
- The car enters the community or parking lot, and as it passes the barrier gate, the barrier arm lowers automatically.
- The JUTAI Single Channel Loop Detector (LD-100/102) ensures safety and anti-smashing functionality during this process.
-
Exit Process:
- When a car exits the community or parking lot, it passes by an inside UHF reader.
- The LD-200/LD-202 triggers the UHF reader, which reads the card and sends the ID to the controller.
- The controller verifies the ID's validity and outputs a relay signal to open the gate barrier for the car to exit.
- As the car passes through the barrier gate, the barrier arm lowers automatically.
- The LD-100/102 provides safety and anti-smashing functionality during this process.
-
Direction Recognition:
- The Direction Recognition Function of LD-200/LD-202 ensures that the double channels loop detector does not trigger the signal again when the car passes another UHF reader, thereby recording only the entry or exit records in the system.
The JUTAI LD-200/202 Double Channel Loop Detector can also function as two independent single-channel loop detectors. This configuration is suitable for standard one-in and one-out parking lots, where there is one barrier and one long-range reader at both the entrance and exit.
In this setup, one loop coil is used to trigger the reader and read the card, while the other loop coil is dedicated to the barrier's anti-smashing function. By utilizing the LD-200/202 as two independent loop detectors, there is a potential cost-saving benefit from an economic standpoint. This setup reduces some of the hardware costs associated with using separate detectors for each function.
This functionality is achieved by enabling the Independent Working Mode feature of the LD-200/202, allowing it to operate effectively in this dual capacity.
