NORTECH PD232 Dual Channel Loop Detector

Product Overview

NORTECH PD232 Loop Detector is a dual channel inductive vehicle detector designed for automatic gates, parking barriers, motorised doors, and access control systems in Abu Dhabi. It detects vehicle presence through two independent loop coils installed under the road surface, helping control safe opening, closing, and traffic direction. The PD232 model is part of Nortech’s 3-Series dual channel loop detector range and operates on 230V AC power. With selectable sensitivity, A-B logic, permanent presence mode, loop isolation protection, and diagnostic capability with DU100, it is suitable for reliable vehicle detection in busy residential, commercial, and industrial automation sites.

Compatibility and Installation Notes

The NORTECH PD232 Loop Detector is compatible with access control systems, automatic barriers, motorised gates, and door automation panels that accept relay outputs from a 230V AC dual channel inductive loop detector. Installation requires correctly designed road loops, proper loop wiring, suitable frequency selection, relay output configuration, and safety integration with the gate or barrier control panel. Professional installation is recommended because incorrect loop geometry, poor cable insulation, or wrong sensitivity settings can cause false detection, missed vehicles, or unsafe barrier movement. For more technical setup details, refer to the official 3-Series product data.
