OVERMOLDED CABLE ASSEMBLIES FOR ADVANCED INTERCONNECT PERFORMANCE ROBERT S. GRZIB, MARKETING MANAGER, CDM ELECTRONICS
Ruggedized cable assemblies are comprised of electronic components specifically engineered to withstand shock and vibration, maintain mechanical and electrical integrity in harsh environments, undergo high mating/unmating cycles, and provide EMI shielding. They are routinely ingress protected (IP65) to withstand the most common cause of interconnect failure, which is fluid and/or particulate ingress that ultimately leads to performance problems or system failure.
brief periods of submersion or moderate-pressure liquid washdown, they are not intended to tolerate physical damage to terminations caused by extreme tensile force, impact, or dust. Furthermore, commercially available ruggedized assemblies with advanced wire termination strain relief are not readily accessible with higher IP ratings (IP66-, IP67-, IP68-, IP69, IP69K), or shielding from electromagnetic interference. These parts likewise fail to support the advanced mechanical/bend protection required to ensure overall mission-critical performance. For these applications, overmolding is the straightforward solution.
While off-the-shelf ruggedized assemblies are preconfigured to maintain their integrity throughout
Ruggedized cable assemblies’ final-inspection requirements include water and steam jet ingress testing.
