Single Channel Loop Detector – PSA02 (Boom Barrier Accessories)
The PSA02 Single Channel Loop Detector is a highly responsive and intelligent sensor system designed to detect the presence of vehicles and automate the operation of boom barriers, parking gates, and industrial entry systems. By identifying metallic objects passing through or stopping over an induction loop, the PSA02 ensures accurate vehicle detection and seamless access control.
Perfect for parking management systems, toll plazas, gated communities, and industrial automation, this loop detector enhances safety, improves traffic flow, and minimizes manual operation.
