Recommended Coil Installation Overview

Proper Installation Orientation

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

• 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)

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

Direction Recognition Function

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
