ldp2ta2b115 – dual ch loop detector 115vac

Why Choose the Carlo Gavazzi LDP2TA2B115 Dual Loop Detector?

The Carlo Gavazzi LDP2TA2B115 is a dual-channel inductive loop detector designed for reliable vehicle presence and movement detection in access control, parking and traffic management applications. Part of the Carlo Gavazzi LDP series, it monitors two inductive loops and detects changes in loop inductance caused by vehicles passing over or stopping above the embedded loop.

Designed for a 115 V AC supply, the LDP2TA2B115 provides two independent loop inputs and two SPST relay outputs rated at up to 1 A / 250 V AC. Automatic adjustment simplifies commissioning, while manual fine-tuning provides additional control where the installation requires optimisation for different loop configurations or operating conditions.

The detector supports a wide 15–1500 µH loop inductance range and is housed in a compact plug-in module measuring approximately 80 × 35.5 × 63 mm. Connection through an 11-pin circular plug, IP20 protection and an operating temperature range of -40 to +70 °C make it a practical control-panel solution for vehicle detection systems.

Reliable Vehicle Detection for Access and Traffic Control

Inductive loop detectors monitor the inductance of wire loops installed beneath a road or access surface. When a vehicle enters the loop's detection area, its metal mass changes the loop inductance, allowing the detector to generate an electrical output for connected gates, barriers, signalling equipment or traffic control systems.

The LDP2TA2B115 provides two loop channels within a single compact module, making it suitable for systems that need to monitor two detection zones. Automatic adjustment, manual fine-tuning and relay outputs allow the detector to integrate with a wide range of vehicle access and traffic automation equipment.

Typical Applications

• Automatic gates and vehicle barriers.
• Car park entrance and exit systems.
• Vehicle presence and passage detection.
• Traffic management and signalling systems.
• Loading bays and industrial vehicle access points.
• Security and access control installations.
