Parking sensor kit Amio TRUCK 4-sensor buzzer system black 19 mm sensors

The Amio TRUCK 4-sensor buzzer system in black is a parking sensor kit developed for reversing assistance on trucks and large vehicles. This set includes four 19 mm ultrasonic sensors designed for installation in rear bumpers and a separate audible buzzer that provides clear proximity alerts to the driver. The system detects obstacles behind the vehicle and emits sound signals of increasing frequency as distance decreases, supporting safer and more confident maneuvering in confined spaces.

Advantages

The kit offers four compact 19 mm sensors that are suitable for tight mounting locations on heavy-duty rear bumpers and panels. The separate buzzer unit provides an audible, easy-to-understand alert without relying on visual displays, which can be beneficial for large-vehicle operation. The sensors use ultrasonic detection to identify obstacles at typical parking distances and communicate proximity with graduated sound cues for intuitive recognition of closing distances.

Suitable for

• Reversing assistance for trucks, vans, and large commercial vehicles
• Rear bumper installation where compact 19 mm sensors are required
• Fleet vehicles that need simple audible obstacle warnings without visual display

Key specifications

• Sensor type: ultrasonic proximity sensors
• Sensor diameter: 19 mm
• Quantity: four sensors per kit
• Alert type: audible buzzer with graduated frequency response
• Installation location: rear bumper or rear body panels
• Colour: black sensors and buzzer housing

How to use

Install the four sensors into the rear bumper or designated mounting points following the vehicle’s bodywork layout, keeping sensors aligned and evenly spaced for consistent coverage. Route the sensor cables to the control unit and connect the buzzer to the system according to the supplied wiring diagram. Power the unit from the vehicle’s reverse light circuit so the system activates automatically when the vehicle is placed in reverse. Test the sensors after installation by moving an object behind the vehicle and verifying the audible alert pattern changes with distance.

Usage recommendations

For reliable performance, ensure sensor holes are clean and free of debris, apply appropriate sealing during installation to prevent water ingress, and avoid mounting near heat sources or metal obstructions that could affect ultrasonic propagation. Periodically check the wiring and sensor alignment, and consult a professional installer if you require integration with other vehicle systems.
