4 LED Reversing Parking Sensors PARKTRONIC Universal system of parking sensors, equipped with 4 sensors and a graphic and sound indicator. The set ensures safer and easier maneuvering of the vehicle. The system monitors the area behind the car and informs the driver when an obstacle is approaching. The device starts automatically when the reversing light is turned on. The speaker beeps when the distance between the vehicle and the obstacle is approx. 0.3 - 2.5 meters. The sound increases as the vehicle approaches an obstacle. The kit detects other cars, bollards, children, animals and small obstacles. Technical data Sensor diameter: 22 mm Power: 12V Power Consumption: <4W Sensors ultrasonic frequency: 40KHz Device operating temperature: -30C to 70C Measurement error: /- 5cm Colour: black Permissible bumper inclination angle: /- 5 Sensor cable length: 2.4 m Power cord length: 70 cm The kit includes: LED display Control unit User manual Double-sided adhesive tape, use the tape to glue the display and the control unit to the car Power cable - connect it to the control unit for 12V in the car Hole saw with a diameter of 22mm to make holes in the bumper 4 sensors, placed in the bumper with long cables to connect them to the control unit. Color BLACK. Description of connections in the system control panel 1. Power - connect the attached cable to 12V in the car 2. Connecting the monitor with the cable coming from the display 3. Connection of 4 sensors equipped with connecting cables LED display Equipped with a long connection cable to the control panel. Signals with diodes and on the digital panel the distance from the obstacle The LED display also signals the distance to the obstacle with an audible signal Correct assembly of the kit in the car - Display - Control panel - 4 sensors Proper installation of sensors We check whether the holesaw and sensors have the same dimension We drill holes for sensors We check the position of the sensor in the car. The inscription UP on the back of the sensor - means that this side of the sensor must be directed upwards Press the sensor to the bumper Correct placement of sensors on the rear bumper Sensors installed definitely improve car safety during maneuvers All 4 sensors have very long cable that allows you to connect sensors to the switchboard Sensors are included in black. This color perfectly matches most car colors. You can always paint the sensor yourself in your own color (this does not affect the operation of the sensors) It is attached to the set 22mm hole saw to make holes in the bumper This is how the cable connections in the parking sensor set look like
