Low Voltage Dual Channel  Loop Detectors For Gate Access Automatic Gate Opener

Jutai offers multi-type voltage vehicle loop detection sensors 110-240VAC and 12-24VADC, which can reduce inventory costs by stocking and transporting just one universal unit. Jutai supplier is your best choice to purchase dual channel loop detectors for controlling the FAAC BFT CAME Gate Barriers. Jutai insists on providing the best service for our global customers, also offer OEM brand if any requirements, in order to help our customer to do their own brands.


Low Voltage Dual Channel Loop Detectors Features

  1. 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.
  2. Diagnostic Capabilities: Comprehensive diagnostics Capabilities allow for accurate diagnosis of loop and Installation problems.
  3. 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.
  4. Loop Frequency Indication: Interference between adjacent loop/detectors can be determined by an integral indication, and eliminated by changing the frequency setting.
  5. 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).
  6. Sensitivity Selection: Sensitivity and frequency of the loop can be adjusted by 7-way dip switch and 10-way dip switch setting.
