Product Description
Sensable vehicle detectors are inductive loop detectors used to detect the presence and movement of vehicles in:
- Parking barriers
- Boom gates
- Industrial doors
- Access control systems
They are described as:
“ideal inductive loop detectors for parking barriers, motorized gates and doors”
Operating Principle
- A loop cable is installed in the ground
- The detector monitors the loop’s inductance field
- When a vehicle passes over:
- Metal mass changes the field
- Detector activates output relay
This is the same principle used by Marantec loop detectors.
Key Features
From Sensable (ULD series):
- Wide self-tuning range
- Strong loop field strength
