High Sensitivity Metal Inductive Loop Sensors For Parking Management System
M1H Loop Detector Description:
Vehicle Loop Detector LD-M1H with direction detecting function that can be used to statistics the vehicle flux. The principle is based on a change in the inductance within the loop which is caused by the metallic components of passing vehicles. The changes are picked up and evaluated by a microprocessor. Ease of use thanks to automatic calibration when the operating voltage is applied.
Key Features
1) When the DIP switch is on position or changing the presence output time, Self-detection
would be done ;
2) ABS align to the pillar which can combine with each other compactly ;
3) Presence output time can be adjustable ;
4) Work mode can be set by the DIP switch ;
5) Pulse output or permanent output can be adjustable .
