EMX-2305-K LRS Vehicle Detector Single Saw Cut Magnetoresistive Detection System

LRS Loop Replacement System Vehicle Detector from EMX Industries is an advanced single saw-cut vehicle detection system designed to replace traditional inductive loops. Utilizing innovative 3-axis magnetoresistive sensing technology, the LRS detects changes in the Earth’s magnetic field caused by ferrous vehicles, delivering highly accurate and reliable presence detection in both above-ground and direct burial installations.

Advanced Detection Without Traditional Loops

The LRS Vehicle Detector eliminates the need for multiple loop cuts, significantly reducing installation time and cost. Its compact, loop-less design features three sensing elements (X, Y, and Z axes) that improve sensitivity and allow flexible installation orientation. Equipped with EMX’s exclusive DETECT-ON-STOP™ (DOS®) technology, the system triggers detection only when a vehicle comes to a complete stop—ideal for ignoring cross traffic in tight access control spaces.

• Single saw-cut installation – no 9-cut loops required
• 3-axis magnetoresistive sensing (X, Y, Z axis selectable)
• DETECT-ON-STOP™ technology to ignore cross traffic
• ULTRAMETER™ sensitivity display for fast setup
• Stand-alone sensor with non-volatile memory storage
• Optional Logic Interface for directional or extended detection

Flexible Integration for Access Control Systems

The LRS system is designed for seamless integration with automatic gates, parking controls, traffic management systems, and commercial access control applications. It supports both pulse and presence outputs and offers relay and NPN (open collector) configurations. The optional LRS-LC Logic Controller provides A-B directionality or increased detection zone capabilities, expanding its application versatility.

• Compatible with gate operators and barrier systems
• Detection range up to 5 ft (1.5 m)
• Pulse or constant presence output selectable
• Reverse polarity and fuse protected circuitry
• Operates in extreme temperatures from -40°C to 82°C
