Reversing parking sensor set buzzer 4 sensors black "gold" 18mm

The parking sensor is a device that supports parking and reversing the car. It works on the principle of sonar - it emits ultrasonic waves, which, when reflected from an obstacle, allow you to determine what distance separates the car from the obstacle. When reversing, the device correctly recognizes obstacles in the way of the vehicle and warns the driver with a sound. Buzzer can work in 3 sound modes: high, low and completely muted. Changing the mode with a switch on the housing. Sensors in the "GOLD" version are smaller than standard and have a hermetic connector on the cable so that we can detach the sensors from the vehicle installation in the event of a bumper removal or damage. The set includes: 4 detectors (sensors) black "GOLD" 18mm, buzzer - emitting sound signals, central unit, hole saw for drilling holes in the bumper.
