Jul 5, 2012 · With very low levels,associated with high gain amplifiers,such as with microphone preamplifiers,the shield of twin shielded cable is normally only connected at one end for just this reason. In coaxial cable,the shield (or more correctly,the outer) is one conductor of the cable,& must be connected for the cable to work.

Aug 30, 2011 · this isn't clearly discussed in most of the writings on USB cable shield grounding. The device I'm developing is a bus-powered device which will likely be in an unshielded plastic enclosure. Thanks in advance for any bits of wisdom on this topic full of contradictory information. I recently posted this question on si-list,

Apr 20, 2016 · Most commercial equipment do not have Faraday cage construction. So energy that supposed to stay on the outside goes into the equipment negating the nice cable shield. If the single ended connected shield lays on grounded cable trays then stray fields are shorted by the grounded tray and the antenna effect is minimized.

Oct 27, 2019 · Note that the signal ground is different than the shield ground. If you use shielded cable it's typically more effective if you connect the shield ground only one end. Keep in mind, also, that RS-485 is not a current loop. Current loop communications need only two wires, as they are not measuring potential.

What is the purpose of grounding the live wire in this circuit????? Serial Port Wiring (Shielding, Twisted Pairs, Grounding)

May 31, 2012 · Are you talking about RF shielding or insulation? Better safe than sorry with insulation. An accidental bump of an exposed wire or live terminal can destroy components, Zap you (12v hurts, and can cause small burns, I know from experience), or even start a fire.

Aug 30, 2011 · The practice showed, that the biggest problem is to find quality USB cable. I tried different certified USB cable but their connection of cable shield to connector shield was done totally bad and useless for EMC immunity and reliability. At …

Mar 11, 2019 · That said for the shield to work, it should be at earth potential. If you have the option to pick which end, use the sourcing end. Grounding the shielded at one end helps eliminate ground loops. Believe me, you want to design a ground loop …

Sep 10, 2014 · the shield contains the rf energy inside, and interferance outside. the rf energy is guided between the inner and shield to prevent leakage into and out of the coax. if yo0u do not connect the shield to ground on at least one end, itis capacitively coupled and …
