EMX LRS-C1 Controller for Single Sensor

The EMX LRS-C1 Vehicle Detector Controller (EMX-2303-2) is part of the Loop Replacement System (LRS), designed to deliver accurate vehicle detection without traditional inductive loops. Using 3-axis magnetoresistive sensing technology, the system detects disturbances in the Earth’s magnetic field caused by vehicles, enabling reliable performance in both above-ground and below-ground installations.

Engineered for simplified installation, the LRS-C1 eliminates the need for multiple saw cuts, reducing labor and material requirements. Its DETECT-ON-STOP (DOS) feature ensures detection only when a vehicle comes to a complete stop, helping minimize false triggers from cross traffic in tight or high-traffic areas.
