Electromagnetic Parking Sensor Buyers Guide

You want to protect your vehicle when you park especially in densely packed areas such as car parks and multistory car parks.  For this very reason you attempt to park your car where it will be protected from dents, scrapes and bangs.

Many cars as standard don’t come equipped with electromagnetic parking sensors.  They very rarely have anything to protect your car from such scenarios especially electromagnetic parking sensors.  Many dealers supply ultrasonic parking sensors and these are a factory upgrade with prices starting at about £300.

To get all around parking protection on your vehicle and to make parking easy and effortless you should have an electromagnetic reversing sensor, as well as a front parking sensor.  The electromagnetic parking sensors make it possible for you to know where your bumpers are at all times in relation to approaching objects.  To help you decide what type of electromagnetic parking sensor you should have we have our electromagnetic parking sensor buyers guide packed with tips, tricks and techniques.

In this comprehensive electromagnetic parking sensor buyers guide we look at both the positive and negative features of two types of parking sensors.  We will also look at the installation of the parking dynamics PD1 parking sensor and the ultrasonic parking sensor.  There is also some technical information regarding the electromagnetic reverse sensor for those inclined to know the ins and outs of the technology used.
Advantages of the PD1 Electromagnetic Parking Sensor:
The first advantage one that the electromagnetic parking sensor gives you is that it is compatible and works on almost every car manufactured today worldwide. Only 4 car models are currently on the incompatible list:
Mitsubishi L200 | Nissan Pathfinder | Nissan Navara | Toyota Rav 4 (Pre 2006)

(The PD1 system is also not compatible with vans.)
Secondly the electromagnetic parking sensor is a no holes, no drill, no damage parking sensor.  This means the actual electromagnetic parking sensors will adhere to the inner side of your front and rear bumpers, without affecting the aesthetics and new factory look of your car.
The electromagnetic parking sensors technology is also only used by a few elite manufacturers and Parking Dynamics.  The reason car manufacturer’s use it is because of the invisible when fitted design coupled with no need for maintenance ensuring a fit and forget product. 
Conversely the ultrasonic parking sensors require maintenance whenever the parking sensors get dirty or is bumped or the performance is affected. They can also get knocked out of alignment by simply washing the car. 
The ultrasonic parking sensor also requires four to eight sensors for the system to work.  In the electromagnetic parking sensor package you have an adhesive metallic tape that is mounted to the inner side of the bumper.  It is the antenna that allows for constant feedback to be sent and received by the ECU Electronic Control Units that triggers the audible speaker to alert you of approaching objects.

The electromagnetic front and rear parking sensor provides you with the ultimate in all round protection.  The revolutionary design allows for the corners and sides of the car to be protected, rather than just a small central path like the ultrasonic parking sensors.
Another advantage to the electromagnetic parking sensors is the voltage that acts like a detector.  The voltage is sent to the sensor so that audible tones can reach the driver.  The tones are offered per zones, i.e. the distance you are to the object.  The closer the electromagnetic parking sensor is to the object the more constant the tone is.  The different zones allow you plenty of time to react before causing potential damage.
The electromagnetic parking sensor is compatible with all conventional wiring systems, as well as the latest CAN Bus wiring systems found on all new vehicles.  The electromagnetic reverse sensor will also work when a tow bar is fitted or a spare wheel is fixed on the rear door. No other parking sensor has this intelligence to recognize and ignore these objects.
The electromagnetic parking sensors have a built in maintenance system that is initialized upon activation.  It will run the diagnostics check and give you real time feedback each time you place the vehicle in reverse or activate the front sensor by pushing the included switch.  Therefore, there is no maintenance required on the electromagnetic parking sensor.
The electromagnetic reversing sensor is a separate system from the front parking sensor.  You will have to engage the electromagnetic rear parking sensor by placing the car in reverse.  For the front parking aid there is a button to push to engage the electromagnetic parking sensor. 
The installation of the electromagnetic parking sensors is fairly easy for any good DIYer.  You may want a trained technician to install the three wires, just to make sure you hook them up properly. But in simple terms there is a live when reverse is engaged, an earth and an aerial wire from ECU to antenna. However, many individuals who work on their cars are able to follow the easy installation instructions that come with the kit. 
Disadvantages of the Parking Dynamics PD1 Parking Sensor:
Any product you buy is going to have some disadvantages.  You already heard some of them about the ultrasonic parking sensor to help us show you the difference in the electromagnetic parking sensor, and why it is a better option.  Now we will look at some of the disadvantages of the electromagnetic rear parking sensor.
First the electromagnetic parking sensors don’t work with the Mitsubishi L200, Nissan Pathfinder, Nissan Navara, and Toyota Rav 4 (pre 2006).  Considering all of the cars on the market this is a tiny disadvantage for a few car owners. The sensor won’t work with these cars as the bumper is built into the rear door and is metal.
The electromagnetic reverse sensor cannot be used on a metal bumper, without modifications. However, this doesn’t exclude metal bumpers at all as if you insulate the metal bumper then the sensor works fine.
The electromagnetic parking sensors can be sensitive to heavy rain however there is an intelligent system built in that enables the sensor to detect rain and adjust the sensitivity accordingly.  The effect occurs due to the rain washing over the bumper where the electromagnetic reversing sensor is fitted.

Now that we have taken a look at both positive and negative features of the electromagnetic parking sensor we can look at a few installation and technical tips regarding the electromagnetic rear parking sensor and front parking sensor. 
Removal of the bumper is required on most cars to install the electromagnetic reverse sensor and is highly recommended, so that you can install the antenna in the correct location. You want to make sure the electromagnetic reversing sensor is at least 40 centimetres from the ground, but the optimal height is 50 centimetres.
Further installation of the electromagnetic reverse sensor does require the black tape offered in the package, but recommend you also use black duct tape or Gaffa tape to cover the full length of the antenna for ultimate in adhesion and protection.
Once the installation of the electromagnetic reversing sensor is complete you will need to run a pre-test to ensure it gives the initial self-diagnostic check and is completely operational at detecting objects.  If you have a metal crash protection bar behind the bumper you have four options of installation on the electromagnetic rear parking sensor. See the Installation page on the website for details:
The technical operation of the electromagnetic parking sensor is fairly simple, but you should read through the technical and installation PDFs found on the website to understand it. 
In essence a magnetic field is created by the electromagnetic parking sensors that transfer data to the transceiver strip on the inner side of the bumper, which then gives you feedback and offers audible sound to you in the vehicle.
The electromagnetic parking sensor reads the size of the object behind you and how close you are.  It can detect people, kerbs, cars, and other objects to keep your vehicle safe in any parking situation, including parallel parking.
In summary the Parking Dynamics PD1 electromagnetic parking sensor is the ultimate choice in car parking sensors giving you a No Drill. No Holes. No Damage option so your car looks as good as the day it left the factory.

Customer Testimonials

I can't believe the ease by which the parking sensor was fitted and we just love the discrete 'hidden' sensor design. What a difference the PD1 makes to both mine and my wife's parking and reversing.

The audible alert keeps our attention to a maximum level and really helps with tight parking spaces.
