There are many different options for cables in any type of machine, system, device or piece of equipment. Cables can be very large, as found in heavy equipment and system automation components, or they can be very small and designed with work with mobile devices or other types of computer or electronic systems.
Cables or wires, in any type of equipment, may need additional protection. For these types of applications, molded cables as opposed to using custom wiring harnesses are often the best choice.
The Difference
A wiring harness is designed to keep cables in a compact bundle and to ensure easy installation and error-free connection. The use of the harness also provides some protection as it prevents individual cables from rubbing or making contact with different surfaces.
With molded cables, the entire cable and the connectors are encapsulated in a carefully selected plastic. In most cases, the connectors are attached to the wire, and then the entire assembly is placed in a custom designed mold. Once the plastic is injected into the mold, the area where the connectors and the cables attach are covered with the liquid plastic that hardens to create a seamless, waterproof cover for the entire cable.
The Benefits
For any type of device or system where the cables are exposed to moisture or high humidity, the choice of the molded option is always the option. With the full coverage of the moisture resistant plastic, there is a limited risk of any damage to the interior cable or where the cable and connector are attached.
This process also allows for protection from other corrosive materials in the environment or in the system. This is often critical in industrial uses and in automation systems in production facilities.
By using molded cables, there is also a longer life cycle for the connection between the connector and the cable. For cables that may be plugged in and removed on a frequent basis, this is an essential consideration.
