Rear Proximity Sensor System

Rear Detection for Safer Reversing

SCC’s Rear Proximity Sensor System enhances driver awareness when reversing by providing clear, distance-based audible warnings. Using ultrasonic detection to monitor the area directly behind the vehicle, it helps prevent collisions with pedestrians, vehicles and other objects in both on-site and urban environments.

Designed for use with SCC’s X-Wire technology, the system can communicate over the vehicle’s existing OEM wiring, simplifying installation and supporting reliable operation on tractor and trailer combinations where connectivity and durability are essential.

  • Designed for use with SCC’s X-Wire technology for simplified installation
  • Detects obstacles and vulnerable road users behind the vehicle
  • Automatically activates with reverse gear
  • Performs a self-diagnostic test at ignition
  • Distance-based audible alerts for clear driver feedback
  • Refined by SCC’s in-house R&D division
  • Supports safer reversing and reduced incident risk

Engineered for Dependable Reverse Detection

SCC’s Rear Proximity Sensor System provides drivers with reliable real-time awareness when reversing, especially in confined areas or locations with limited visibility. The ultrasonic sensors continuously monitor the rear danger zone when reversing and provide escalating audio tones to help drivers judge distance and avoid contact.

When deployed using SCC’s X-Wire technology, the system sends signals over the vehicle’s existing OEM wiring, eliminating the need for additional data looms between tractor and trailer. This reduces installation complexity and helps minimise common failure points in traditional rear detection setups.

With fully automated activation through reverse gear, built-in diagnostics and a robust design suited to heavy fleet use, the system delivers consistent, practical reversing assistance across a wide range of vehicle types.

Who is this for?

SCC’s Rear Proximity Sensor System is ideal for fleets operating in environments where reversing manoeuvres are frequent or visibility is limited.

Typical applications include:

  • Haulage and logistics fleets operating HGVs and rigid vehicles
  • Construction and utility vehicles manoeuvring in confined or complex sites
  • Municipal and service fleets operating in pedestrian-dense areas
  • Waste and recycling vehicles conducting frequent reversing
  • Any fleet seeking dependable rear detection using SCC’s X-Wire technology

What compliance does this help with?

SCC’s Rear Proximity Sensor System supports safer reversing and low-speed manoeuvring as part of wider Work-Related Road Risk (WRRR) management, Mission Zero, and a range of site-access and operational safety policies used across construction, utilities, logistics and municipal operations.

Whilst rear proximity sensors are not part of the Direct Vision Standard (DVS) Progressive Safe System and do not fulfil FORS vision-aid requirements on their own, they remain a valuable supplementary measure when used alongside compliant camera and alert systems.

When combined with SCC’s rear cameras and monitoring solutions, the system contributes to a more complete safety setup for fleets operating in demanding or high-risk environments.

Specifications

  • Operating Voltage: 9-30V DC
  • Operating Frequency (ultrasonic): 40kHz
  • Current consumption:
    • 12V: Module 45mA / Display 40mA (standby) / 155mA (active)
    • 24V: Module 60mA / Display 40mA (standby)  / 165mA (active)

What problems does it solve?

Reversing incidents remain a leading cause of low-speed collisions, downtime and avoidable fleet costs. Drivers often struggle with blind zones behind the vehicle, depth perception limitations and the challenge of detecting pedestrians or objects close to the rear bumper.

SCC’s Rear Proximity Sensor System addresses these challenges by monitoring the rear hazard zone and providing clear audio tones that increase as objects approach. This helps drivers react earlier, maintain safe manoeuvring control and prevent avoidable damage.

When deployed with SCC’s X-Wire technology, the system also eliminates the wiring complexity typically associated with trailer-mounted safety equipment, providing automatic activation and reliable operational consistency across varying tractor-trailer combinations.

Got Questions?

We know fitting safety equipment to your vehicles isn’t always straightforward – especially when it comes to compatibility, installation and compliance. Below are answers to some of the most common questions we get about this product. Click to reveal the answers.

Are Cheaper Imported Trailers Really Cheaper?

Sometimes, but often not.

A lower purchase price can be attractive, particularly when managing capital costs or expanding a fleet. However, the real cost of a trailer is determined over its working life, not just at the point of purchase.

In high-utilisation operations, costs typically appear in areas such as downtime, parts availability, support, and residual value. When a trailer is off the road, revenue stops. Even small increases in downtime or delays in sourcing parts can quickly outweigh an initial saving.

For example, if a trailer generates daily revenue and is unavailable for just a few additional days per year due to parts delays or extended repairs, the financial impact can exceed the original price difference over time.

There are situations where a lower-cost trailer may be the right decision, such as short-term contracts, lighter duty cycles, or lower annual mileage. In these cases, reducing upfront cost can align with the operating model.

However, in more demanding environments, where uptime, durability and support are critical, the higher-cost option at purchase often delivers a lower and more predictable cost over its working life.

The key question is not which trailer is cheapest, but which delivers the lowest overall cost based on how it will be used.

Does it activate automatically when reversing?

Yes. The system activates when reverse gear is selected and performs a self-check at ignition.

Is this compatible with trailer setups?

Yes. When used with SCC’s X-Wire technology, it works across tractor and trailer combinations without extra cabling.

How does the system alert drivers when reversing?

It uses distance-based audible tones to warn the driver of nearby obstacles as they reverse.
