Vehicle magnetic detector PROXIMA MDP_R (radio) — magnetoresistive traffic sensor, wireless communication

PROXIMA MDP_R is a magnetoresistive vehicle detector that detects passing or stationary vehicles by sensing disturbances in the Earth's magnetic field. The device uses a magnetoresistive sensor to register changes caused by metallic masses and transmits detection events via radio link for integration with traffic control systems, vehicle counters, parking management platforms or barrier controllers. The wireless design minimizes installation work compared with inductive loops and supports deployments where trenching or lane closures are undesirable.

Advantages

The PROXIMA MDP_R provides cable-free communication between the detector and the receiver, reducing infrastructure complexity and enabling rapid installation. Its magnetoresistive sensing offers stable detection performance for both moving and stopped vehicles and requires no periodic lane cuts or loop replacement. Radio connectivity allows remote placement of sensors and simplifies integration into existing traffic control and parking systems. The device is designed for low maintenance and continuous operation in roadside and parking environments.

Suitable for

• Lane vehicle detection as a replacement for inductive loop sensors
• Parking bay occupancy monitoring and access control
• Vehicle counting on entry/exit points
• Integration with barrier controllers and local traffic controllers
• Temporary or permanent installations where non-intrusive sensors are preferred

Key specifications

• Detection principle: magnetoresistive sensor sensitive to magnetic field disturbances
• Communication: wireless radio transmission for event reporting and integration
• Detection modes: detection of passing and stopped vehicles
• Installation: non-intrusive mounting in or on pavement or on curbside boxes depending on site requirements
• Power: low-power operation suitable for battery or external supply (site-dependent)
• Environmental suitability: designed for outdoor operation in roadside and parking conditions

How to use

Install the PROXIMA MDP_R at the recommended position relative to the traffic lane following the manufacturer's mounting instructions and local installation standards. Configure the radio link and detection parameters using the supported receiver or configuration software to match lane width, typical vehicle profiles and desired detection sensitivity. After alignment and parameter tuning, validate detection performance with test passes and adjust sensitivity or filtering to avoid false positives from nearby metallic structures or transient magnetic disturbances. Ensure periodic checks of the mounting and radio connectivity as part of routine site maintenance.

Usage recommendations

Place sensors away from large stationary metal masses and maintain recommended separation from power lines and other radio-emitting equipment. For optimal detection of stopped vehicles, adjust sensitivity and filtering parameters according to local vehicle mix and typical parking positions. Use a secure and tested radio receiver or gateway compatible with traffic control systems to ensure reliable event delivery and integration.
