loop detector, we are a professional manufacturer of loop detectors and our products have take up over 50% of domestic market.

Loop DetectorTLD-500

    TLD-500 single channel 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, opeating barriers, controlling traffic light systems or activating card dispensers in parking lots.It uses the advanced microprocessor technology, and can work in diverse environments. TLD-500 has two-way output relays. One is unlimited output when loop is temporarily covered, while the other is multi-mode that can be set by users.
