ldp1sa1b230 – single ch loop detector 230vac

Why Choose the Carlo Gavazzi LDP1SA1B230 Single Loop Detector?

The Carlo Gavazzi LDP1SA1B230 is a reliable single-channel inductive loop detector designed for vehicle detection in parking, access control and traffic management applications. As part of the Carlo Gavazzi LDP1 loop detector series, it detects changes in the inductance of an installed ground loop when a metallic vehicle enters or passes through the detection area.

Designed for dependable vehicle sensing, the LDP1SA1B230 features automatic detection-level adjustment, manual sensitivity selection and selectable operating frequencies to help minimise interference between adjacent loops. LED indication provides clear visual information for power, relay status and loop faults, while pulse and presence operating modes support a variety of gate, barrier and access-control requirements.

With a 230 V AC nominal supply, an operating supply range of 195–265 V AC at 45–65 Hz and support for loop inductance from 15–1500 µH, the LDP1SA1B230 provides flexible integration into vehicle detection systems. Its compact plug-in housing uses an 11-pin circular connection for straightforward installation and replacement.

Key Advantages

Reliable Vehicle Detection for Access Control

Inductive loop detectors operate by monitoring the inductance of a wire loop installed in or beneath the road surface. When a metallic vehicle enters the loop area, the loop inductance changes and the detector processes this change to operate its relay output. This provides a dependable method of detecting vehicles without requiring physical contact with the vehicle.

The Carlo Gavazzi LDP1 series is designed for applications including parking systems, drive-through installations and access control equipment. Automatic adjustment, selectable sensitivity and frequency settings help simplify commissioning while providing reliable detection in installations where multiple loops or changing environmental conditions may be present.

Typical Applications

• Automatic gates and powered gate systems.
• Vehicle access-control installations.
• Car park entrance and exit barriers.
• Rising barriers and traffic-control equipment.
• Vehicle counting systems.
• Drive-through vehicle detection.
• Industrial doors and loading-area access systems.
• Parking and traffic management systems.
