Detailed Product Description

Single/double vehicle loop detector is used for wherever vehicles have to be detected, for example for monitoring and safe-guarding accessways or for counting vehicles. The output signal can be used for controlling door and gate drive mechanisms, operating barriers, controlling traffic light systems or activating card dispensers in parking lots. WJDG201 connects one inductive loop, while WJDG202 connects two.
