EMX Industries 2301-K LRS-DB-50-K Loop Replacement System

Overview

The EMX Industries 2301-K (LRS-DB-50-K) is a Loop Replacement System featuring advanced 3-axis magnetoresistive sensing technology that detects the presence of vehicles by responding to changes in the Earth's magnetic field caused by ferrous objects. Three sensing elements provide measurements in the X, Y, and Z axes to improve detection sensitivity in both above and below ground installations. The compact, loop-less design reduces installation costs compared to traditional inductive loop technology.

Key Features

• Three-dimensional presence detection of vehicles via 3-axis magnetoresistive sensing
• Select X, Y, or Z axis independently
• DETECT-ON-STOP™ (DOS®) — EMX exclusive feature that allows detection only when a vehicle has come to a complete stop; requires vehicle to stop for a minimum of 1 second (1–2s typical)
• Stand-alone sensor with non-volatile memory stores ambient background and settings
• ULTRAMETER™ displays optimum sensitivity setting and crosstalk interference
• 10 sensitivity levels (0–9)
• Automatic environmental tracking and compensation
• Local magnetic field nulling — averages local field signature in any sensor orientation
• Pulse/presence mode — allows relay/NPN output to send either a pulse or constant presence output
• Reverse polarity and fuse protected supply circuitry
• Remote control module for programming and additional relay contact output
• Optional Logic Interface for extended detection
• Detection range: 1.5m (5 ft.)
