Electromagnetic Parking Sensor System With Sound

Functions of Electromagnetic Parking Sensor System With Sound:
1.Detection in all directions without dead angle
2.Totally built-in installation with damage effect to the car appearance
3.The sensor antenna is installed inside the bumper,W/O any
any drilling
4.During approaching to an obstacle,the electronic unit activates the acoustic signalling with 3 types of signals:
A continuous sound ofa beepa approximately between 0-0.3m
A short interval sound ofa beepa approximately between 0.3-0.5m
A long interval sound ofa beepa approximately between 0.5-0.7m

Technical Characteristics :
