Ultrasonic V's Electromagnetic Technology:


There are 2 types of parking sensor technologies available on the market. The older technology is ultrasonic that typically uses 4 or 6 sensors that mount in the bumper for all to see. Holes need drilling in your bumper to mount and they need painting to match your bumper colour. Ultrasonic sensors work by sending and receiving an ultransonic signal and detecting anything that enters this signal and converting this to an audible noise for you to react accordingly.

Many ultrasonic systems are physically too deep to install in to bumpers, due to the crash protection bar behind the bumper. The Electromagnetic sensor eliminates this problem!

The PD1 uses a unique Electromagnetic Technology, typically used by a few elite car manufacturers and offers a design that discretely mounts preserving the 'new factory look' of your vehicle, so only you will know it is fitted.

Ultrasonic technology having 4 or 6 visible and exposed sensors does need regular maintenance and cleaning. Electromagnetic technology is not exposed, is self diagnostic and requires no maintenance.

Many accidents occur because drivers can't see the corners of their car and how far the edge of the bumpers protrude from the rest of the body. The electromagnetic design allows for this, as the antenna covers the entire length of the bumper and this is superior to the ultrasonic type that cannot detect objects at the very corners and onto the sides.

No Visible Parts, Period! The electromagnetic sensors when fitted are completely discrete and totally invisible. Only you will know it's fitted. This ensures a no-holes installation, a higher value to your car—and a more desirable car.

No-Drill! The electromagnetic PD1 is fitted without drilling your bumper and is completely 100% discrete and invisible when on the vehicle. Unlike ultrasonic type parking sensors that require ugly sensors to be mounted in your bumper and then painted. No need to match the paint colour, and run the risk of getting your hands and clothes full of paint, spending hours scrubbing your hands and washing paint brushes.

Electromagnetic Car Parking Sensor Technical Operation:

When reverse gear is selected the small control unit generates a magnetic field and transfers this to the transceiver adhesive strip that is placed on the inner side of and run the length of your bumper.

The magnetic strip then sends out an elliptical magnetic field to cover the full area around your bumper, rear and sides. The transceiver strip works by sending and receiving unlike ultrasonic parking sensors that require 2 types of sensors, one to send and one to receive; if they become dirty the ultrasonic performance can deteriorate.

Mass is then monitored by the control unit by translating this into a voltage. When an object (i.e. people, kerbs, cars, etc) heavier in mass than the magnetic field enters this elliptical zone, an increase in voltage is detected by the control unit and you are then informed by a series of audible tones how close you are to the object. You can then manoeuvre accordingly with plenty of time to react.
