CTCS Interconnection System 

A world of transportation

Similarly to the automotive market, the transportation market is advancing in the areas of safety, connectivity, and efficiency. However, despite many similarities, it has higher performance requirements and must abide by more stringent government regulations on emission reduction.

First, commercial and recreation vehicles are often exposed to higher levels of environmental forces, including vibration, dust, water, debris, and temperatures. Second, to address the evolving emission regulations, powertrain components are designed to be more efficient, in turn driving complexity in the electrical system and requiring higher component reliability. These two factors drive the demand for more robust connection systems designed specifically with the market’s unique conditions in mind.

Designed for the green truck generation

CTCS connector and CTS terminal family
has been designed to meet the demanding requirements of commercial and heavy duty applications, specifically to address new emission regulations and enable the generation of environmentally friendly vehicles. This heavy duty connection system provides superior resistance against vibration and environmental forces, protecting the integrity of the electrical system from high operating temperatures, debris, and water.

CTCS/CTS family 
serves as a reliable backbone to all vehicle electronics, including powertrain, safety, entertainment, and telematics.
