Molex 5559 Mini-Fit Jr. 4pin 4.2mm Pitch Custom Power Cable Assembly

1.     How to choose a Right Cable?  

A designer has to evaluate the determining system parameters such as signaling rate, cable length, single-ended or differential (balanced) signaling, point-to-point, multidrop or multipoint configuration, noise margin, flexibility, and costs.

2.    What's Will Impact the Material You Select?  

      Specific equipment, machine structure, and environment.   

3.    Regarding number 2, what should be concerned?  

Unshielded or shielded (taped, braided, or combination of both)?   
Round or flat? Coaxial, multi conductor or twisted pair cable?

4.   Why cable needs to be shielded?  

     To reduce electrical noise from affecting the signals and to reduce electromagnetic radiation that may   

      Interfere with other devices.

     5.    What sort of cable need suggest to? 

A braided or served shield is recommended to ensure good isolation between the signal lines and the environment.

6.   Does double-shielded cable that is taped and braided typically perform better?  

Yes.

7. What kind of cable is cheaper and easier to handle?   

Multi conductor cables are cheaper and easier to handle than twisted pair or coaxial cables, especially in terms of termination.

8.   What is your recommendation for differential data transmission, such as LVDS?   

The    twisted pair cable is recommended since it provides two identical conductors to transmit the signal and its complement.
