Breaking Down the Features of Dethmers Manufacturing Company 9599004 Smi Delta Force

Specifications

The Dethmers Manufacturing Company 9599004 Smi Delta Force is built around a core of advanced technology designed to enhance trailer braking. Its primary innovation lies in the Self Modulating Integrated (SMI) brake controller utilizing patented SMI wireless technology. This wireless connection allows the coach to send braking contours directly to the actuator at highway speeds, ensuring rapid response to dynamic driving situations.

The system employs dual-signal proportional technology, which is the key to its consistent brake feel across all speeds. This means the braking force applied to the trailer directly mirrors the pressure applied to the truck’s brake pedal, regardless of whether you’re crawling in traffic or cruising at highway speeds. The forced braking action feature further refines this, ensuring optimal brake feel without requiring excessive pedal travel, even at higher speeds. Safety is also paramount, with built-in logic to provide the necessary braking force to avoid runaway vehicle scenarios.

The physical design of the actuator is equally impressive. It features a flexball actuator mount, a design choice that Dethmers Manufacturing Company highlights as being 75% smaller than competitor models. This compact size not only contributes to a cleaner installation but also simplifies the mounting process, reducing potential interference with other vehicle components. The wireless coachlink eliminates the need for complex wiring runs between the controller and the trailer brakes, simplifying installation and troubleshooting.
