PD132 Inductive Vehicle Loop Detector for Car Park Barriers
PD132 Inductive Vehicle Loop Detector for Car Park Barriers
PD132 Inductive Vehicle Loop Detector — Reliable Access Control for Car Parks & Barriers
The PD132 Inductive Vehicle Loop Detector (model KINGJOIN&GALO PD132) is a professional-grade, single-channel loop sensor engineered for seamless integration with car park barriers, gate controllers, and vehicle access systems. With adjustable sensitivity, multi-voltage compatibility, and fail-safe operation, the PD132 delivers consistent, accurate vehicle detection in both commercial and industrial environments. Made in Guangdong, China (Mainland).
Key Features & Functions
- Reset Switch: Manually reset the detector during registration and testing for easy system recovery.
- Selectable Pulse Time: Configure the pulse relay output duration to either 0.5 seconds or 1 second to suit your access system requirements.
- Pulse Relay Selection: The pulse relay can be set to activate either on vehicle arrival or vehicle departure from the loop — giving you full flexibility in trigger logic.
- Sensitivity Reinforcement: Maximizes detection sensitivity at the un-detecting threshold, ensuring large vehicles such as trucks are reliably detected.
- 4-Level Sensitivity Adjustment: Four switch-selectable sensitivity settings let you fine-tune detection for different vehicle sizes and loop configurations.
- 4-Level Frequency Adjustment: Four frequency settings minimize cross-interference when multiple loops operate in proximity.
- Filtering Option: Introduces a pre-detection delay to eliminate false triggers from small or fast-moving objects (e.g. pedestrians, motorcycles at speed).
- Permanent Presence Option: Maintains vehicle detection output when a vehicle stays within the loop area for extended periods — no drop-out on stationary vehicles.
- Fail Safe with Signal: CE-certified safety mode ensures the system defaults to a safe state in the event of signal loss.
- Available in Red or Black — customizable options available for distributors and bulk orders.

Frequently Asked Questions
Q: What is an inductive vehicle loop detector and how does the PD132 work?
A: An inductive vehicle loop detector works by embedding a loop of wire into the road surface. When a vehicle (which contains metal) passes over or rests on the loop, it changes the loop's inductance. The PD132 monitors this inductance change and triggers a relay output — which can then open a barrier gate, activate a traffic signal, or log an access event. The PD132 is a single-channel detector supporting loop inductance from 50 µH to 1000 µH.
Q: What voltage options does the PD132 inductive loop detector support?
A: The PD132 is highly versatile, supporting AC 230V, AC 115V, 24V DC/AC, and 12V DC/AC, making it compatible with a broad range of barrier controllers and access systems worldwide.
Q: How do I reduce false detections with the PD132 loop sensor?
A: The PD132 includes a built-in Filtering Option that introduces a configurable delay before the output relay switches, which prevents false triggers from fast-moving or lightweight objects. Additionally, the 4-level frequency adjustment helps eliminate cross-interference when adjacent loops are installed nearby.
Q: Is the PD132 vehicle loop detector compatible with all car park barrier brands?
A: Yes — the PD132 outputs a standard relay signal (presence and pulse relay selectable) that is compatible with virtually all major barrier gate brands and access control systems. Always verify your barrier controller's relay input specifications before installation.
