Product Overview

PD-110B vehicle detector is a single vehicle door detector designed for reliable vehicle presence detection in automatic barrier, electric door, and quick door systems. Manufactured by S4A, the PD-110B works through an inductive loop coil principle, where vehicle metal changes the loop inductance and the microcontroller analyzes the signal to confirm vehicle presence. For Abu Dhabi parking entrances, commercial access points, villas, and barrier gate systems, this detector helps improve automation safety and operational control. Its industrial-grade design, adjustable sensitivity, loop self-diagnosis, and drift compensation make it suitable for demanding vehicle access control applications. A dual-channel option is the S4A PD-232 Dual Channel Vehicle Loop Detector.

Compatibility and Installation Notes

The S4A PD-110B is compatible with vehicle access systems that use an inductive loop coil for presence detection, including compatible electric doors, quick doors, and boom barrier gate control systems. Correct loop cutting, cable routing, probe lead length, relay wiring, and sensitivity adjustment are important for stable detection. Professional installation is recommended to avoid false triggering, electrical wiring errors, and incorrect coil placement. For confirmed dimensions and technical parameters, review the S4A product parameter page.

How does the S4A PD-110B confirm a vehicle is over the loop within 35 ms?

The S4A PD-110B works on the inductive loop principle: a vehicle’s metal changes the loop inductance, and an onboard microcontroller analyses the signal to confirm presence. Its 35ms reaction time helps the relay output respond quickly as vehicles roll over the loop at Abu Dhabi barriers.

What does the three-stage delay on the S4A PD-110B do for automatic barrier closing?

The S4A PD-110B has a three-stage adjustable delay, with the first gear at 0.7 seconds. Paired with a compatible boom barrier, it supports automatic closing after the vehicle passes. Confirm the other stage timings on the S4A parameter page before setting delays for an Abu Dhabi lane.

The S4A PD-110B supports an 8m × 1m coil and a 10m probe lead — how should the loop be laid out?

The S4A PD-110B supports a maximum coil of 8m × 1m with a probe lead within 10 metres. At Abu Dhabi barriers, keep the detector within 10m of the loop and plan loop cutting and cable routing carefully, since incorrect coil placement can cause false triggering.

Why do loop self-diagnosis and drift compensation matter at Abu Dhabi sites for the S4A PD-110B?

Loop self-diagnosis on the S4A PD-110B checks the coil’s condition, while environmental drift compensation keeps detection stable as temperature and moisture shift loop inductance. With three sensitivity levels (low, medium, high), installers can tune detection to vehicle types and loop conditions.

At AED 150, how does the S4A PD-110B compare with the NORTECH PD132 single-channel detector?

At AED 150, the S4A PD-110B costs AED 375 less than the NORTECH PD132 (AED 525). It has one relay output and three sensitivity levels, while the PD132 adds a second relay and DU100 diagnostics. The packing contains the detector only. Contact POWERgate Abu Dhabi on WhatsApp +971 50 884 4933.
