Parking Dynamics PD1 Parking Sensor vs. Ultrasonic Sensors

There are two types of parking sensors on the market: the electromagnetic parking sensor and the ultrasonic parking sensor. The ultrasonic parking sensor is an older technology. It was created to produce an ultrasonic sound to bounce of an object that then sends the signal to you in the car. Before the signal can reach you it must go to another parking sensor that will receive the information. The ultrasonic parking sensor set up has 4 to 6 sensors for sending and receiving information. You also have a smaller area the sensor can read for objects in the way.

The electromagnetic parking sensor has a magnetic pulse it sends out to read objects on the entire bumper, including the corners and sides. There are two sensors with the PD1 car parking kit. You have a front parking sensor, and a reversing parking sensor. The sensors are able to send and receive, rather than needing two sensors to send and one to receive like the ultrasonic parking sensor.

Steel Mate and Laserline are ultrasonic parking sensors. The Steel Mate works on metal bumpers, but so does the PD1 car parking sensor. The PD1 just needs a small modification in order to fit to the metal bumper. The electromagnetic parking sensor is also an “invisible when fitted” parking sensor. It is a no holes no drill parking sensor. It will not change the appearance of your bumper in the least. The Ultrasonic parking sensor requires bumper modification and matching paint. As you can see there are several reasons why the electromagnetic parking sensor is the best.
