The Carlo Gavazzi LDP1SA1B115 is a single-channel inductive loop detector designed for reliable detection of vehicles and other large metallic objects using an inductive wire loop installed in the ground or roadway. Operating from a 115 V AC supply, it provides a practical detection solution for access control, parking, traffic management and automated gate systems.
The detector accepts one inductive loop input with a broad loop inductance range of 15–1500 µH. Automatic adjustment simplifies commissioning, while manual fine-tuning allows the detection sensitivity to be adapted to the installation. This combination helps provide reliable vehicle detection across a wide variety of loop sizes and site conditions.
The LDP1SA1B115 uses an 11-pin circular plug-in connection and provides an SPDT relay output rated at 1 A / 250 V AC. Its compact 80 × 35.5 × 63 mm module housing, LED indication, IP20 protection and operating temperature range of -40 to +70 °C make it suitable for installation inside protected control panels and enclosures.
Inductive loop detectors such as the Carlo Gavazzi LDP1SA1B115 operate with a wire loop installed beneath or within a roadway surface. The loop forms an inductive sensing circuit, and when a large metallic object such as a vehicle enters the loop area, the electrical characteristics of the loop change. The detector recognises this change and operates its relay output, providing a reliable signal to connected control equipment.
This technology is widely used for automated gates, barriers, parking systems and traffic control because the sensing element can be installed beneath the road surface with no exposed mechanical detector. The LDP1SA1B115's broad 15–1500 µH loop range, automatic adjustment and manual fine-tuning provide flexibility when commissioning different loop geometries and vehicle-detection applications.
