Introduction to 89891-430H

The 89891-430H header system is a proven, standard interconnect solution for a broad range of applications. Utilizing a unique signal/harness assembly and molex\'s proven header contact design, they offer a cost-effective interconnect solution that can be applied in nearly any electronic product space.

Application Field and Working Principle

The 89891-430H headers are ideal for applications such as automotive, telecommunications, consumer electronics, industrial control, medical and many others where high-speed signal and power transmission are required. These headers can also be used in a variety of rugged applications, including military and aerospace, due to its high EMI shielding robustness. The 89891-430H headers feature a four-way design, with a two-way common signal along the top and two-way, isolated data signals down the side. The terminal block has a polarized contact block which ensures correct mating and is designed to prevent mating mismatches in the field. The contact blocks and contact elements are rated up to 13A and they are designed to protect the contacts from environmental stresses such as shock and vibration.The 89891-430H headers utilize a proven header contact design which ensures reliable performance in any application. The contact elements are designed to provide adjustable current carrying capacities from 1A to 13A and are dramatically more reliable than traditional screw terminals. The contacts are also designed to be corrosion and oxidation resistant and provide very low insertion forces and contact pressure for superior contact integrity.Finally, the 89891-430H headers also feature an integrated EMI shielding, which makes them suitable for use in high EMI/RFI environments. The power and signal contacts are integrated with a conductive shield which provides reliable EMI/RFI protection and improves signal integrity. The EMI shield also provides an effective method for controlling EMI/RFI signals emanating from the application to other parts of the system.

Conclusion

Overall, the 89891-430H headers are designed to provide a robust, reliable interconnect solution for a variety of applications. They feature a four-way design, with a two-way common signal along the top and two-way isolated data signal down the side. The contact elements provide adjustable current carrying capacities from 1A to 13A. The integrated EMI shielding makes them suitable for use in high EMI/RFI environments. This combination of features makes them ideal for a wide range of applications, including automotive, telecommunications, consumer electronics, industrial control, medical and many others.
