| High Light | dual channel loop detector ，vehicle loop detector for traffic counting ，LD200 loop detector direction detection | ||
The JUTAI Dual Channel Loop Detector models LD200 and LD202 are professional grade detection devices designed for advanced vehicle monitoring applications. Utilizing two independent inductive loops, this detector not only identifies vehicle presence but also determines the direction of travel, making it ideal for traffic counting, parking management, and access control systems where monitoring bidirectional flow is essential.
With two completely separate channels, each with its own sensitivity adjustment and relay output, the device offers unparalleled flexibility. It supports multiple operating modes configurable via DIP switches, including directional detection, presence hold, and pulse output modes to suit a wide array of industrial and commercial applications.

Sensitivity and frequency adjustment is facilitated through a 7-way dip switch and 10-way dip switch settings. Users can choose from 8 different sensitivity settings by configuring the dip switch positions according to the provided tables.
Dip switches 6, 7, and 8 govern CH1 sensitivity, ranging from 0.8 (least sensitive) to 0.015 (most sensitive).
Dip switches 3, 4, and 5 control CH2 sensitivity, ranging from 0.8 (least sensitive) to 0.015 (most sensitive).
Switch 1 (S1): Channel 1 Loop Function Selection (10 way dip switch)
DIP 1 & DIP 2: Special Sensitivity Increase For Both Trailer (Both Channels)
D3, D4, D5 and (Switch 2=S2) D1, D2: Setting Special Functions (Mode1, 2, 3 Direction Detection. Mode 4, 5, 6 Normal mode, two loop detection are separated)
D6 & D7 & D8 and (Switch 2=S2) D3 & D4 & D5: Setting CH1 and CH2 Sensitivity Selection (Eight Levels Choices)
D9 & D10 and (Switch2=S2) D6, D7: Setting Frequency (20 K to 100 KHz)
Reset Button: Please note: The LD-200 must be reset every time a setting change is made to the Dip switches.
When installation, please keep the product plug and socket in the vertical direction
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.
Entry Process:
Exit 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.
