PD-132 24V Vehicle Loop Detector

PD-132 24V Single-Channel Vehicle Loop Detector UAE

PD-132 24V is a professional single-channel inductive vehicle loop detector designed for automatic parking barriers, sliding gates, vehicle access control and traffic-management applications. The detector identifies the presence of a vehicle through an inductive loop cable installed beneath the road surface.

This 24V PD-132 loop detector provides a fast 10 ms response time, four adjustable sensitivity levels and a wide operating frequency range of 20 kHz to 170 kHz. It can be used for automatic barrier opening, vehicle-presence detection and safety-loop applications depending on the connected gate or barrier controller.

PD-132 24V Technical Specifications

*Confirm the voltage printed on the detector label before connection. PD-132 units are manufactured in different supply-voltage versions.

How the PD-132 Vehicle Loop Detector Works

The PD-132 operates with an inductive loop cable installed beneath the roadway. The loop creates an electromagnetic field. When a vehicle passes over or stops above the loop, the metal mass of the vehicle changes the loop inductance.

The detector recognizes this change and activates its output relay, allowing the connected gate, parking barrier or access-control system to respond according to its programming.

Fast 10 ms Vehicle Detection

With an approximate 10 millisecond response time, the PD-132 can quickly detect vehicles entering the loop area. Fast detection is useful for automatic parking barriers and vehicle access systems where the controller needs an immediate detection signal.

4 Adjustable Sensitivity Levels

The PD-132 provides four adjustable sensitivity levels. This allows the installer to tune the detector according to the loop size, installation conditions and type of vehicle being detected.

If the sensitivity is too high, unwanted or unstable detection may occur. If it is too low, smaller vehicles may not be detected reliably. Correct loop construction and sensitivity adjustment are therefore important.

Loop Inductance & Cable Requirements

The PD-132 supports a total loop inductance of approximately 50 μH to 1000 μH. For normal installations, the recommended loop inductance is approximately 100 μH to 300 μH.

The connection cable between the road loop and detector should be kept as short as practical, with a maximum recommended length of approximately 20 metres. The lead cable should be twisted at least 20 times per metre to reduce electrical interference.

Vehicle Presence & Safety Loop Operation

The PD-132 can be used as a vehicle presence detector. When a vehicle remains above the inductive loop, the detector can maintain its output according to the selected presence setting.

This makes it suitable for parking barrier safety applications where the barrier should not close while a vehicle remains within the protected detection area.

Automatic Parking Barrier Opening

The detector can also be connected to a compatible barrier controller's OPEN input. When a vehicle reaches the loop, the PD-132 relay sends an opening command to the barrier controller.

This configuration is commonly used for automatic exit lanes where vehicles should open the barrier without requiring a remote control, access card or push button.
