- Coil Cutting Size and Embedding Guidelines are as shown in the
diagram on the right.
- It is recommended to use ferromagnetic wires for the induction
coil, with a total length of up to 500 meters.
- The cutting size of the coil should be a rectangle with a length of
1.0 to 2.0 meters and a width of 0.8 to 1.2 meters, avoiding right
angles at corners as much as possible.

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.
