Why Choose the Carlo Gavazzi LDP2PA2DU24 Dual Loop Detector?

The Carlo Gavazzi LDP2PA2DU24 is a reliable dual channel inductive loop detector designed for vehicle detection and access control applications. Part of the Carlo Gavazzi LD loop detector series, this plug-in loop inductance amplifier provides accurate vehicle presence monitoring for barriers, gates, parking systems and industrial access equipment.

The LDP2PA2DU24 supports two inductive loops and operates from a wide 24–240 V AC/DC supply. With adjustable sensitivity, automatic sensitivity boost, frequency tuning and directional logic, it provides flexible detection performance for demanding vehicle monitoring applications.

Designed for easy integration, this detector features a plug-in connection, dual SPDT relay outputs, loop diagnostics and configurable pulse or presence switching modes. Its compact housing and IP30 protection make it suitable for installation in control cabinets and access control systems.

Key Advantages

  • Reliable dual loop vehicle detection technology for access control applications.
  • 24–240 V AC/DC universal power supply for flexible installation.
  • Two independent loop inputs for vehicle presence and directional detection.
  • Automatic Sensitivity Boost (ASB) improves detection of high-bed vehicles.
  • Adjustable sensitivity and frequency tuning for reliable operation.
  • Advanced diagnostics simplify installation and maintenance.

Key Features

  • Carlo Gavazzi LD dual loop detector series.
  • Dual channel inductive loop detection.
  • Plug-in connection design.
  • Loop inductance range: 20 µH to 1,000 µH.
  • Adjustable sensitivity from 0.01% to 1%.
  • Automatic and manual frequency tuning.
  • Four adjustable loop frequency channels.
  • 2 × SPDT relay outputs.
  • Selectable pulse or presence switching.
  • Directional logic for dual loop operation.
  • Multicolour LED indication for power, fault and loop status.

Reliable Vehicle Detection for Access Control Systems

Inductive loop detectors such as the Carlo Gavazzi LDP2PA2DU24 detect vehicles by measuring changes in the electromagnetic field generated by buried loop sensors. When a metallic vehicle enters the detection area, the change in inductance is analysed and the relay outputs are activated.

The LD series provides advanced configuration options including sensitivity adjustment, frequency management and loop fault diagnostics. These features allow reliable operation in parking facilities, industrial entrances and automated barrier systems where accurate vehicle detection is required.

Typical Applications

  • Automatic gates and barrier systems.
  • Parking access control installations.
  • Vehicle counting and traffic monitoring.
  • Industrial entrance automation.
  • Bollard and security access systems.
  • Drive-through vehicle detection systems.
