Has anyone fitted an electromagnetic parking sensor in their 997 rear bumper? Backing up my car is a PITA sitting in my GT3 seats... this might be a quick and cheap way to alleviate that pain.

Apparently these use a stick-on electromagnetic strip on the inside of the bumper and the control module simply taps into your reverse light wire. Should be an easy install since our bumpers are so easy to remove. Anyone try this?

I'm thinking something like this: http://www.dx.com/p/car-electromagne...5#.U2Ua-6U2JUQ

here's an install video I found on Youtube:

 

Thats nice. I may look into that. Cabriolet in parking garages with columns is a PITA backing up. When the top is up of course.

 

I'd be interested in something like this for my F430. Wondering how well they work and which ones are the best.

 

I like the fact that this is invisible. I wonder if you could also install it in the front spoiler lip to prevent damage from those concrete parking barriers.

 

I wonder the same thing. Does anyone know if this requires a metal barrier to trigger? Granted, most concrete have tenses but I wonder about its sensitivity.

 

you got me wondering the same... I Googgled and it seems that electromagnetic sensors are not triggered by metal - they will sense any object. I found this info from Ebay on Ultrasonic vs. Electromagnetic sensors:

"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!

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.

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.

I think I'm going to order one of these things and give it a go

 

I would think it will work provided you tap into a power source that is on when the key is on.

 

I like the fact that it's under 20 bucks. Worth giving it a shot the next time I have to take my bumper off

 

Forsa355,

Thx for the research. This saved me the time.
