Reno BX-4 Loop Detector – Single Channel 12–24V

12-24V Single Channel Vehicle Loop Detector for Traffic Control

The Reno BX-4 by EDI is a high-performance single-channel loop detector designed for vehicle detection in secure access systems. Engineered for 12–24V DC or 24V AC operation, this detector features dual relay outputs, eight selectable sensitivity levels, and multiple output modes - making it an ideal solution for barrier gates, slide gates, traffic lanes, and industrial access points.

Equipped with TruePresence™ detection, delay timers, and automatic sensitivity boost, the BX-4 provides reliable performance even in high-bed vehicle and noisy electrical environments. Its fail memory and LED diagnostics allow for real-time fault indication, making troubleshooting fast and efficient.

Designed for use in perimeter access and traffic control applications. Mounts in a standard detector rack or surface enclosure. Harness sold separately.
