EMX LRS-C1 Controller for CarSense 303 Sensors

Sensor Controller for EMX CarSense 303 Loop Replacement System

The EMX LRS-C1 is the required controller module for use with LRS-DB (direct burial) and LRS-FP (flat pack) magnetoresistive vehicle sensors in the CarSense 303 system. This controller stores, manages, and calibrates all detection settings and relays output to gate or barrier systems - making it the central intelligence behind EMX’s advanced loop replacement technology.

Equipped with ULTRAMETER™ sensitivity display, a fail-safe SPDT relay, and customizable presence or pulse output modes, the LRS-C1 offers reliable vehicle detection and easy integration into modern access control systems. Whether for perimeter security, gate automation, or safety loops, this controller ensures fast response and secure communication between sensor and operator.

Required for all LRS CarSense 303 sensors. Controller only - sensors sold separately.
