The traffic detectors of the TDD1-2MW series use Doppler radar technology for detecting vehicles. They are designed for detecting objects moving in or through the field of view.
TYPICAL APPLICATIONS
The detectors of the TDD1-2MW series have been developed for a range of applications that require robust and reliable detection:
- Green-phase request or extension at traffic lights, with possibility to discriminate by vehicle driving direction
- Speed-dependent detection of vehicles
- Door sensor: As detector for auto-operation of doors
WORKING PRINCIPLE
The TDD1-2MW detectors detect moving objects by means of the frequency shift of the reflected microwave vs. the transmitted waves. Several application-dependent features can be configured easily and effortlessly using the IR remote control (extra accessory):
- Direction-discrimination (approaching, receding, both)
- Detection range (depending on model)
- Minimum speed threshold (4 km/h, 8 km/h)
- Auto-timer output activation (off, 90 s, 150 s)
- Feedback LED on front of detector (on, off)
MOUNTING
The recommended mounting location is on a pole at the side
of the road, approximately 1 m to 5 m above ground.
ACCESSORIES:
IR Remote Control:
To customize the settings of the detector, an infrared remote control is required. The remote control is an extra accessory and has to be ordered separately.
Mounting Accessories:
Pole mount adapter for mounting the detector on a round pole. The pole mount adapter is an extra accessory and has to be ordered separately.
Connection Cable:
An according connection cable is necessary for the electrical connection of the detector. This cable is an extra accessory and has to be ordered separately.
