Installation Guidelines

Use ferromagnetic wires for induction coil (up to 500 meters total length)
Coil cutting size: Rectangle 1.0-2.0m length * 0.8-1.2m width
Avoid right angles at corners
Keep product plug and socket in vertical direction during installation

Recommended Coil Installation Overview

Proper Installation Orientation

System Integration

JUTAI LD200/202 Double Channels Vehicle Loop Detector Series with direction recognition function for single-channel entry and exit applications.

Compatible Components

JUTAI One door controller (Model: AC-11)
JUTAI gate barrier (Model: BR-110)
JUTAI long-range RFID reader (Model: PUHF-9)
High-temperature resistance loop coils (Model: JTHT-11)

Operation Process

Entry Process

Simultaneous Loop Coil Activation: Both loop coils are pressed when car enters
UHF Reader Activation: LD-200/202 triggers UHF reader at entrance
Card ID Reading: Reader transmits ID to controller via Wiegand output
ID Verification and Gate Opening: Controller verifies ID and opens gate barrier
Vehicle Entry: Barrier arm automatically lowers after vehicle passes
Safety Assurance: LD-100/102 provides safety and anti-smashing functionality

Exit Process

UHF Reader Activation: LD-200/202 triggers inside UHF reader
ID Verification and Gate Opening: Controller verifies ID and opens exit barrier
Vehicle Exit: Barrier arm lowers automatically after vehicle passes
Safety Measures: LD-100/102 provides safety during exit process

Direction Recognition

Ensures double channels loop detector does not trigger signal again when car passes another UHF reader, maintaining accurate entry/exit records.

Direction Recognition Function

Independent Working Mode

The JUTAI LD-200/202 can function as two independent single-channel loop detectors for standard one-in and one-out parking lots:

One loop coil triggers reader and reads card
Other loop coil provides barrier anti-smashing function
Cost-saving benefit by reducing hardware requirements
