EMX LRS-FP Carsense 303 Flat Pack Sensor

Saw-Cut Flat Pack Magnetoresistive Sensor – CarSense 303 Series

The EMX LRS-FP CarSense 303 is a flat-pack magnetoresistive vehicle detection sensor engineered for fast installation in saw-cut slots in asphalt or concrete. This high-sensitivity probe serves as a non-intrusive, cost-saving alternative to inductive loops, providing 3-axis detection in a compact, low-profile form. The fixed orientation of the LRS-FP improves installation accuracy and axis tuning, making it ideal for gate operators, access control, and safety loop applications.

This sensor requires the LRS-C1 controller (sold separately) for operation, programming, and calibration. It stores settings locally and offers reliable long-term performance when installed properly in epoxy-filled saw cuts.

This listing is for the sensor only. Controller required for operation.
