Reliable Vehicle Detection for Gate and Barrier Control Applications
The 3-Series Single Channel Vehicle Detector delivers dependable performance for parking facilities, commercial entrances, and industrial sites where precise vehicle sensing is essential. Whether installed at warehouse loading docks, residential gate systems, retail parking barriers, or high-speed industrial doors, this microprocessor-based detector ensures consistent operation across demanding environments with temperatures ranging from -40°C to +80°C.
Site managers at corporate campuses and logistics centres rely on these detectors for their automatic sensitivity boost feature, which maintains accurate detection of both standard vehicles and high-bed lorries. The selectable permanent presence function prevents premature barrier closure—critical for sites with frequent vehicle throughput. Available in boxed (PD130) and PCB (PD139) formats, installation teams can choose the configuration that best suits their cabinet requirements, while the optional DU100 diagnostic unit enables performance verification without disrupting operations.

Auto-Tune
Self-tuning frequency eliminates manual calibration and prevents interference with adjacent loops.
Wide Range
Operates from -40°C to +80°C with sealed circuits protecting against condensation.
Flexible Output
Selectable presence or pulse modes with fail-safe relay contacts rated at 5A for direct barrier control.
Diagnostic Ready
Compatible with DU100 diagnostic unit for non-disruptive performance monitoring and historical fault analysis.
The boxed PD130 series offers three voltage variants: PD131 operates on 120V AC, PD132 on 230V AC, and PD134 on 12-24V AC/DC. The PCB-based PD139 operates on 24V AC/DC, making it suitable for integration into existing barrier controller power supplies.
ASB automatically increases detection sensitivity when a vehicle with high ground clearance (such as lorries or SUVs) enters the loop zone. This ensures reliable detection of vehicles that might otherwise fall below the standard sensitivity threshold, preventing false undetect events.
Yes. The optional power fail memory feature retains vehicle presence status during power interruptions and detects vehicles that arrive while power is off, providing immediate detection when power restores. This is essential for rising bollard applications where undetected vehicles could cause damage.
The detector self-tunes across a 20-1500μH inductance range, accommodating most standard loop configurations from small vehicle bays to larger entrance loops. The 4-step adjustable frequency (12-80kHz) allows fine-tuning based on specific loop geometry.
The boxed PD130 mounts on a shelf or DIN-rail socket using an 11-pin submagnal connector (86CP11). The PCB-based PD139 uses panel or plug-in mounting with a Molex 10-pin female connector. Flying lead options are available for both variants.
