Professional 110-240VAC Double Channel Vehicle Loop Detector: Modes
of Operation
The LD-200 series detector offers versatile operation modes,
catering to various application requirements:
Presence Mode: In this mode, the detector remains active as long as
a vehicle is present within the loop detection area. It provides a
continuous output signal as long as the vehicle occupies the
detection zone.
Pulse Mode: In Pulse Mode, the detector generates a single pulse
output signal when a vehicle is detected within the loop area. This
mode is suitable for applications where a single signal pulse is
required upon vehicle detection.
AB Logic Presence Mode (Barrier Operation): This mode employs AB
logic, where the detector triggers the barrier operation based on
the presence of vehicles. It ensures smooth barrier operation,
allowing vehicles to pass through efficiently and safely.
AB Logic Pulse Mode (Counting Logic): In AB Logic Pulse Mode, the
detector utilizes AB logic for pulse output signals. It enables
counting logic, where each pulse represents a detected vehicle,
facilitating accurate vehicle counting and monitoring.

Installation Precautions and Troubleshooting:
- Coil Cutting Size and Embedding Guidelines are illustrated in the
diagram on the right.
- It is advisable to utilize ferromagnetic wires for the induction
coil, with a total length of up to 500 meters.
- The coil cutting size should be a rectangle with dimensions ranging
from 1.0 to 2.0 meters in length and 0.8 to 1.2 meters in width,
minimizing right angles at corners whenever possible.

Working Principle
| Entry Process | Exit Process |
|---|
| 1. Both loop coils are pressed as a car enters. | 1. Car passes by an inside UHF reader as it exits. |
| 2. LD-200/202 triggers the UHF reader at the entrance. | 2. LD-200/202 triggers the UHF reader, which reads the card ID. |
| 3. UHF reader sends the ID to the controller (AC-11). | 3. Controller verifies ID's validity and opens gate barrier. |
| 4. Controller outputs a relay signal to open the gate barrier. | 4. Car exits as barrier arm lowers automatically. |
| 5. Car enters and barrier arm lowers automatically. | |
| 6. LD-100/102 ensures safety and anti-smashing functionality during
this process. | 5. LD-100/102 provides safety and anti-smashing functionality. |
Direction Recognition
The Direction Recognition Function of LD-200/LD-202 ensures that
the detector does not trigger the signal again when the car passes
another UHF reader, recording only the entry or exit records in the
system.
Application
- JUTAI LD200/202 double channels vehicle loop detector series,
equipped with direction recognition function, suitable for many
single-channel entry and exit cases.
- Can connect to JUTAI One door controller (Model: AC-11), JUTAI gate
barrier (Model: BR-110), and JUTAI long-range RFID reader (Model:
PUHF-9), combined with high-temperature resistance loop coils
(Model: JTHT-11), ideal for single-channel entry/exit access
control systems.
Functionality as Two Independent Single-channel Loop Detectors
- LD-200/202 can function as two independent single-channel loop
detectors, suitable for standard one-in and one-out parking lots.
- One loop coil triggers the reader and reads the card, while the
other is dedicated to the barrier's anti-smashing function.
- This configuration reduces hardware costs associated with using
separate detectors for each function, offering potential
cost-saving benefits from an economic standpoint.
- Achieved by enabling the Independent Working Mode feature of the
LD-200/202, allowing it to operate effectively in this dual
capacity.
