Dolphn Standard Sensor Diameter (25mm)

Vs

Dolphin MICRO Sensor Diameter (20mm)

The Dolphin Micro Parking Sensor kit comes with 4 recess mounting sensors. With Display that is designed to attach to the roof lining at the rear of the vehicle so it can be seen in the rear-view mirror giving you an indication of the distance behind you. There is also sounder built into the display that gets quicker the closer you are to any obstacle. Detection range starts at 1m and gets you to 30cm at which point you get a continuous tone to alert you to stop.  

All of our kits now come with the new watertight swap socket feature based 6 inches from the sensor heads, it makes installation quicker and easier. Also should you ever have a problems with faulty sensors or accident damage in the future it facilitates easy replacement without having to remove the bumper again and rewire from scratch. 

How it works 

The system works by radiating ultrasonic beams throughout the area behind the vehicle. The beams are then reflected by obstructions behind the vehicle, and re-enter the sensors. The control box uses the reflected beam information to calculate the distance of the obstruction. 

As with the other systems the Dolphin unit is activated when reverse gear is engaged. As the vehicle is reversing. When the vehicle is less than 1.25 metres from the obstruction the audible alert will emit intermittent bleeps. As the vehicle gets closer to the obstruction the frequency of the bleeps increases. At 30 centimetres from the obstruction the bleeps become a continuous solid tone.
