Inductive Vehicle Loop Detector for Car Parking Management System
Quick Detail:
The PD-123 is a single channel inductive loop detector designed for parking and access control applications.
The detector is connected to an inductive loop mounted in the road surface. When vehicles pass over the loop the detector switches on an output.
The use of microprocessor and surface mount technology enables a large number of functions to be incorporated into a small package.
The PD-123 is compatible with most single channel detectors on the market and is easy to set-up and install.

| Operating temperature | -20°C to +65°C |
| Storage temperature | -40°C to +85°C |
| Frequency range | 20 kHz to 170 kHz |
| Reaction time | 100ms |
| Loop inductance | Ideal:80μH to 300μH |
| (incl. conn. wiring) | max:50μH to500μH |
| Loop connection | <5m optimal |
| Loop connection wiring | Maximum length 200 meters |
| Twisted at least 20 times per meter | |
| Dimensions | 36 x74x85 mm |
Application
Loop detectors are used wherever vehicles have to be detected. Like monitoring and safe guarding access ways to counting vehicles. The output signal can be used for controlling door and gate drive mechanisms, operating barriers, controlling traffic light systems in car parks or activating card dispensers in car parks.
The PD-123 is a single channel inductive loop detectors. The principle is based on a change in the inductance within the loop which is caused by the metallic components of passing vehicles. The changes are picked up and evaluated by a microprocessor. Ease of use thanks to automatic calibration when the operating voltage is applied.
