Magnetometer Vehicle Detector

Magnetometer vehicle detectors identify the presence, passage, and classification of vehicles by measuring the distortion each vehicle causes in the Earth’s magnetic field as it passes over or near a buried or surface-mounted sensor. These detectors serve traffic management, access control, parking systems, toll enforcement, and security perimeter monitoring applications where reliable vehicle detection is needed without above-ground infrastructure that drivers can damage or obstruct.

Each vehicle contains ferrous metal components — engine blocks, chassis, axles, and body panels — that distort the local magnetic field in a characteristic pattern as the vehicle moves through the sensor’s detection zone. Single-axis magnetometer detectors identify the presence or absence of a vehicle in a defined zone. Multi-axis three-component sensors capture the full vector field disturbance, enabling vehicle classification by magnetic signature — distinguishing motorcycles from passenger cars, and empty trailers from loaded ones based on the spatial and temporal profile of the magnetic anomaly.

In-ground installation places sensors below pavement level in small-diameter bore holes — avoiding road surface disruption and eliminating sensor exposure to vehicle impact, weather, and vandalism. Wireless magnetometer detectors transmit detection data via Zigbee, LoRa, or cellular links to traffic management servers without requiring buried data cables between sensors and infrastructure. Battery life on wireless in-ground units ranges from 3 to 7 years depending on detection activity and transmission frequency — making them directly suitable for deployment across large parking facilities and road networks without frequent maintenance visits.

Output interfaces include relay contacts for barrier and gate control, RS-485 Modbus for traffic controller integration, and REST API for cloud-connected smart parking and traffic analytics platforms. Detection response time runs under 100 milliseconds from vehicle entry to output trigger.

These detectors serve Pakistan’s motorway toll plazas, Lahore and Karachi smart parking management systems, military base vehicle entry control points, industrial estate gate management operations, and Punjab Safe Cities Authority traffic counting and classification programs requiring reliable, infrastructure-minimal vehicle detection across high-volume road positions.

Tactical Supply Pakistan supplies magnetometer vehicle detectors for traffic management, toll enforcement, parking systems, and security access control procurement across Pakistan.
