What do CAM Adapters do?

When it comes to towing safety and performance, having reliable braking is essential. For trailers equipped with electric-over-hydraulic (EOH) brake actuators, signal compatibility between the truck and the trailer can sometimes be a challenge. That’s exactly why the CAM Adapter was created; it’s a smart solution that ensures your tow vehicle and trailer braking systems communicate perfectly.

And here’s an important advantage: All Deutsche Hydrapro actuators have the CAM technology built into the internal circuit board, which means no external adapter is required when using a Deutsche Hydrapro actuator.

The Problem: Mismatched Signals Between Truck and Trailer

In a traditional electric trailer brake system, the tow vehicle sends an electrical signal to power the brake coils, which are small electromagnetic components located inside each wheel assembly. These coils create resistance in the circuit, allowing the brake controller to recognize that a trailer is connected and functioning properly.

However, electric-over-hydraulic brake actuators don’t use these coils. Instead, they rely on advanced electronics and hydraulic pressure to apply the brakes. Because of this difference, the truck’s brake controller doesn’t see the same type of electrical resistance it expects, often leading to:

❌ Connection or error messages on the brake controller display
❌ Weak or inconsistent braking response
❌ Loss of proportional control when towing

The Solution: Deutsche Hydrapro’s CAM Adapter

The CAM Adapter bridges the communication gap between your truck’s brake controller and your trailer’s EOH actuator. It’s designed to mimic the behavior of the brake coils found in a traditional electric brake setup without actually needing them.

Instead of using simple resistors that waste energy and dull the signal, the CAM Adapter uses inductors, electronic components that store energy in a magnetic field and release it back into the system at just the right moment. This process creates what’s known as a reactive load, which perfectly imitates the natural resistance of real brake magnets.

The Result: Reliable, Proportional Braking

By using the CAM Adapter, your electric-over-hydraulic brake actuator receives the proper signal strength and timing from the brake controller. This ensures:
✅ Accurate brake controller communication
✅ Consistent, proportional braking performance
✅ Prevents error codes and connection issues
✅ Smooth, safe towing in all conditions
