The JUTAI Two Channel Loop Sensor is a dedicated solution for parking entry/exit management, featuring precise direction judgment and dual-channel flexibility to streamline traffic flow and occupancy tracking. It works seamlessly with parking barriers, access control systems, and guidance tools, adapting to shopping malls, residential complexes, airports, and logistics centers—while functioning as either a coordinated directional system or two independent single-channel sensors.

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.
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 Switch 2 (S2) D6, D7: Setting Frequency (20 K to 100 KHz)
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 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.
