Reversing sensor system with buzzer in the license plate frame The system is equipped with a Buzzer that emits a repetitive signal with increasing frequency as the obstacle is approached. Easy installation without the need to drill holes in the bumper as with conventional sensors Precise measurement of the distance from an obstacle in the range of 1.5 m -> 0.01 m The adjustable measuring angle of the sensors allows the frame to be mounted also in unusual recesses for the license plate IP68 weather resistance Universal ultrasonic, 3-sensor parking sensors are equipped with a Buzzer that emits an audible signal that increases its sound frequency as the distance from the obstacle decreases. The sensors activate automatically when reverse gear is engaged. The kit includes: 3 ultrasonic sensors in the selected color integrated into the whiteboard frame Buzzer - sound signal Central module - sensor controller Matching fragments of self-adhesive double-sided tape - for the buzzer and the central module. Kit connection instructions The perfect gift box Technical Specifications: Power supply: 12V (10.5V-16V) IP68 - water resistance and protection against dust, sand and dirt Power consumption: <4W Supply current: 40-300mA Buzzer dimensions: 42 mm (diameter) x 17 mm (height) Device operating temperature: from -40C to 80C Ultrasonic frequency of sensors: 40 KHz Sensor cable length: 2.4 m Power cord length: 70 cm Parking assist system Includes 3 ultrasonic sensors with an audible obstacle signaling system Perfect performance in all conditions Falling rain does not affect the operation of the device , while the sensors have an IP69 waterproof class, which means that they are perfectly protected against water , dust and any dirt entering the device. Safety through precision The sensors are calibrated to accurately detect even the smallest obstacles , such as parking posts, city barriers, high curbs, etc. Intuitive beep The distance from the obstacle modulates the frequency of the signal as it gets closer to the obstacle. This will allow the driver to react at the right moment.
