Product special: 1: There is a light bar on the display, which can distinguish different orientations of obstacles. 2: Buzzer reminder, when the obstacle is closer, the alarm will be faster. Specification: 1: Rated voltage: 12V DC 2: Rated current: 100mA-300mA 3: Ultrasonic frequency: 40KHz 4: Control module operating temperature: -30-80 degrees Celsius 5: Display working temperature: -20-70 degrees Celsius 6: Sensor diameter: 22mm 7: Installation method: drilling For each order product, we will be responsible for testing and packaging to ensure that high-quality products can be delivered to you quickly. There are ABCD and 4 light bars on the display, which represent the data of each sensor respectively. The light bar changes with the distance of the obstacle, so that the driver can knowthe position and distance of the obstacle. The information displayed on the display is quite rich.Through different numbers and light bars, the position and distance of different obstacles are displayed. The numbers, light bars, and sound help the driver to park better. We use a good control and design, so that each sensor can be tightly connected, and will not cause poor contact due to the vibration of the ca r. We have been engaged in reversing radar products for 13 years and are quite professional. The sensors we use are dual-angle detection and large detection chips. This makes the productdetection more accurate and does not produce false alarms.
