Ultrasonic detection sensors provide close-range object detection around your vehicle, alerting drivers audibly and visually when something enters the danger zone. SM UK supplies and fits sensors configured for the front, side, corners, or rear of your HGV – individually or in combination for wider coverage.

All systems feature Environment Learning Mode, which filters out false alerts from tow-hooks and other fixed ancillary equipment, so warnings stay meaningful.

• Audible and visual distance warnings
• Flush-mount and underslung fixing options
• Environment Learning Mode to reduce false alerts
• Low speed trigger module available across all systems
• CE and UKCA marked, UNECE R10 compliant

The internal alarm works in conjunction with ultrasonic sensors to alert the driver when an object enters the detection zone. An audible warning increases in frequency as the distance closes, prompting the driver to stop or take evasive action. An optional visual display can be added to provide a graduated proximity indication – useful in noisy cab environments where audio alone may not be sufficient.

The buzzer features adjustable volume control and will silence automatically after four seconds if no movement is detected from the object or vehicle, reducing alert fatigue without switching off the system. A self-diagnostic function monitors system health and flags any faults to the driver.
