Marine environments present some of the biggest challenges for electrical components. Extreme temperatures and the corrosion effects of moisture, salt, and even oil can lead to degradation of your cable and the components. OCP understands these requirements and works with our customers to achieve the best product possible. We have always only sourced the highest quality components for our customers.


Our cables are flexible and can withstand high temperatures and harsh environments. It’s important to partner with a manufacturer that is focused on staying in step with the demands of the marketplace. We deliver cables that are specifically engineered and manufactured to meet these high standards. If your needing Dress pack cable assemblies or sensor embedded cable assemblies give us a call.


In today’s day and age, with the agricultural industry’s technology growing by leaps and bounds our customers are requiring that their cable assemblies be built to be able to keep up with the changes and of course withstand some of the harshest environments including continual repetitive movement’s. OCP has been manufacturing cables for 30+ years and we have built a reputation with our customers around the quality of our assemblies.


Our customers require cables that can withstand extremely harsh environments and repetitive use without being compromised. OCPs custom cables are weatherized IP6X for our bulk cable and assembly designs. OCP cables are also temperature rated as well as oil & chemical rated & we always include validation testing on all projects.
