Set of reversing parking sensors buzzer 4 sensors black "gold" 18 mm amio-01576

The parking sensor is a device that assists in parking and reversing the car. It works on the principle of sonar - it emits ultrasonic waves, which, after reflection from an obstacle, allow you to determine the distance between the car and the obstacle. When reversing, the device correctly recognizes obstacles in the vehicle's path and warns the driver with a sound.  The buzzer can operate in 3 sound modes: high, low and completely muted. Changing the mode using the switch on the housing. The "GOLD" version sensors are smaller than standard ones and have a hermetic connector on the cable, so we can disconnect the sensors from the vehicle's installation in the event of bumper disassembly or damage. The set includes: 4 black "GOLD" 18mm detectors, a buzzer - emitting sound signals, a control unit, a hole saw for drilling holes in the bumper. assembly instructions Full specification: Operating range/sensitivity 0-2.5m Power supply 12V Operating frequency 40KHz Operating temperature -30°C - +70°C Mounting diameter 18mm
