EMX Carsense 303 Flat Probe Vehicle Detection Kit

Flat Pack Vehicle Detection Kit for Saw-Cut Installations

The EMX CarSense 303 Flat Probe Kit includes the LRS-FP magnetoresistive sensor and LRS-C1 controller, offering a complete vehicle detection solution that replaces traditional loop systems with fast, reliable, and non-intrusive installation. Designed for saw-cut concrete or asphalt, the flat probe installs in a single 2" x 3/8" slot and seals with epoxy—eliminating the need for full loop cuts.

With 3-axis magnetic field sensing and the ULTRAMETER™ sensitivity display on the controller, this kit enables precise tuning for exit and safety loop applications. Its compact size, low power draw, and customizable output make it ideal for high-security gate operators, barrier arms, and automated entry systems where loop cutting is impractical.

This is a complete plug-and-play detection kit for saw-cut vehicle detection. Just add epoxy and wire it into your gate system.
