QXNY Parktron Parking Sensor Backup Radar Plane 4 Rear Sensor for Bumper Adjustable Depth To Assist Bumper Distance System

Sensor Installation Requirements 1: Rear installation height must exceed 50 cm . 2: Ensure the sensor surface is perpendicular to the ground.Critical Note: The sensor must not detect the ground.Error 1: Height less than 50 cmError 2: Surface not perpendicular to the groundError 3: Surface tiltedWorking principle of the product: When the product is working, the sensor emits ultrasonic waves. When encountering an obstacle, the ultrasonic waves are reflected. The sensor receives the reflected signal and transmits it to the control box. Through calculation, the control box obtains the distance between the vehicle and the obstacle, and reminds the driver to pay attention through the display and sound, etc., to avoid danger. It is a good helper for us to drive the car!Product parameters 1>Specifications: 2>Rate voltage: 9V~14V DC 3>Rate operating range: 10.5V - 16V DC 4>Rate current: 100mA - 300mA 5>Ultrasonic frequency: 40KHz 6>Control moudle working temperature: -30 - 80 celcius degree 7>Display working temperature: -20 - 70 celcius degree 8>Sensor diameter: 16.5mm 9>Installation mode: Drilling Alarm sound: beep The box is specially designed to lock the wires tightly and avoid bad contact due to vibration of the car! OUR PARKING SENSORSDouble Angle - horizontal and vertical simultaneous scanning probe!  Package includes:1 x Control Box 4 x Parking Sensors 4 x Sensor extension cables 2.3M 1 x Power Cable 1 x Hole Saw 1 x Buzzer 1 x User manualLegal Disclaimer This product is designed as an parking aid and must be used with caution.
