The VD108B is single channel inductive loop detectors. Loop detectors are used wherever vehicles have to be detected. 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. VD108B output is TTL mode.
