Double Channel Metal Loop Detector LD200 Auto Vehicle Car Access Detection

Double Channel Metal Loop Detector

JUTAI dual channel loop detectors that provide higher detection speed and flexibility. With 12ms detections time in both single and two-channel versions, the new dual-channel loop detectors are significantly faster than before. As a result direction detection of a vehicle at high speed is achievable. This LD-200 are also available as 1/2-channel loop detector in a plastic housing for direct mounting on DIN rail.

Double Channel Metal Loop Detector Features

Compact Size: the compact and well engineered housing .Combines all of the industry requirements regarding Features and functionality and allows this detector to be Incorporated into any or existing traffic detection system.

Diagnostic Capabilities: Comprehensive diagnostics Capabilities allow for accurate diagnosis of loop and Installation problems.

Selectable Presence Time: The output of the presence relay can be selected to limit a detect output to a fixed time(time>30 minutes)while a vehicle remains on the loop

Loop Frequency Indication: Interference between adjacent loop/detectors can be determined by an integral indication, and eliminated by changing the frequency setting.

Direction Detection : (If the vehicle moves from CH1 to CH2, then CH1 relay output; if the vehicle moves from CH2 to CH1, then CH2 relay output).

Sensitivity Selection: Sensitivity and frequency of the loop can be adjusted by 7-way dip switch and 10-way dip switch setting.

Double Channel Metal Loop Detector Specifications

Loop Detector Switch Setting Instruction

1. Sensitivity and frequency of the loop can be adjusted by 7-way dip switch and 10-way Dip switch setting.
2. The user can select 8 different setting by changing the setting of the dip-switch to different modes as in the Dip-switch setting tables below. Dip switch 6,7 and 8 for CH1 sensitivity selection with 0.8 being the least sensitive and 0.015 being the most sensitive.
3. Dip switch 3,4 and 5 for CH2 sensitivity selection with 0.8 being the least sensitive and 0.015 being the most sensitive.

JUTAI Loop Detector Selling Point

• High-temperature stability, used in kinds of environment
• Environment drifting compensate automatically
• Multilevel lightning protection
• With the function of sensing loop malfunction automatically (disconnection or cutting-out)
• Cooperate with the barrier gate to realize vehicle anti-hit and automatic close function

Double Channel Metal Loop Detector Applications

Jutai Universal-Voltage loop detectors are used wherever vehicles have to be detected. Like monitoring and safe guarding access ways to counting vehicles. The output signal can be used for controlling door and gate drive mechanisms, operating barriers, controlling traffic light systems in car parks or activating card dispensers in car parks.
