EMX Industries 2305-2 Loop Replacement System LRS-FP-50

Overview

The EMX Industries 2305-2 Loop Replacement System (LRS-FP-50) eliminates the need for traditional inductive loop cuts by using advanced 3-axis magnetoresistive sensing technology that responds to changes in the Earth's magnetic field caused by ferrous objects. Three sensing elements measure the X, Y, and Z axes independently to improve detection sensitivity in both above-ground and below-ground installations. Its compact, loop-less design reduces installation costs compared to traditional inductive loop technology.

Key Features

• Three-dimensional presence detection of vehicles across X, Y, and Z axes
• Exclusive DETECT-ON-STOP™ (DOS®) — detects only when a vehicle has come to a complete stop (minimum 1 second, 1–2s typical), ideal for ignoring cross traffic in tight spaces
• Stand-alone sensor with non-volatile memory storing ambient background and settings
• Automatic environmental compensation and local magnetic field nulling — averages local field signature in any sensor orientation
• ULTRAMETER™ displays optimum sensitivity setting and crosstalk interference
• 10 sensitivity levels (0–9)
• Pulse/presence output — relay/NPN output configurable for pulse or constant presence
• Optional Logic Interface for extended detection with additional relay contact output
• Reverse polarity and fuse protected supply circuitry
• FP sensor housing: Polyamide; IP69K environmental rating
