Functions: Electromagnetic parking sensor detects obstacles behind the car according to the reflection principle of electromagnetic wave, the system comprises of an electronic box, an antenna sensor and a buzzer or display

Features:
1) Detection in all directions without dead angle
2) Totally built-in installation with no bad effect to the car appearance
3) The sensor antenna is installed inside the bumper, no need for drill on the bumper
4) During approaching to an obstacle, the electronic unit activates the acoustic signaling with 3 types of signals - A continuous sound of "beep" approximately between 0-0.3m - A short interval sound of "beep" approximately between 0.3-0.5m - Al long interval sound of "beep" approximately between 0.5-0.7m

Technical characteristics:
Working voltage: DC12V +/- 2V
Currency consumption: <50mA
Working temperature: -20~+70º C
Detection range: Approximately in 0.7m
