GMAX brand dual-channel vehicle loop detector, model GM-705B. Unlike single-channel models, this advanced device can simultaneously monitor two independent inductive loops. It is widely used in parking management systems, toll gates, and automated barrier controls to reliably detect the presence, passage, and direction of vehicles. It is highly suitable for complex access control points requiring advanced logic. The device plays a crucial safety role by preventing a barrier arm from closing onto a vehicle, while also optimizing traffic flow through automatic triggering.
