Single Channel 24V Induction Loop Detector with 40m Teflon insulated cable


Product Information


Product Code: APC-LD1-24VAC/DC

Single Channel Loop Detector


Usage of Loop Detector:
The APC-LD1 is a loop detector sensor module that is used wherever vehicles need to be detected. The loop detector can be connected to any of the following types of systems that allow the use of a loop detector:
- Driveway Gate Mechanisms
- Operating Barrier Mechanisms
- Traffic Light Systems in car parks

How it Works:
The loop detector is housed in the controller box/enclosure of the connected mechanism and is used to communicate with the underground inductive loop wire when a vehicle is detected which then sends a signal to the connected system to open the mechanism, close the mechanism or prevent the system from closing.
