Securing electrical cables to holes in enclosures?

Suppose I would like to insert data-cables of varying diameters -- e.g., a cable of 5 mm diameter -- into the 6 mm diameter hole of a plastic enclosure. The wires within the cable are terminated via soldering to a PCB inside the enclosure. What…

Why isn't stripping wires by burning with a lighter a more common practice?

I see people suggesting specialized tools, or trying it manually with sharp knife or scalpel, why not just burning the rubber for a second or two with a lighter and just pulling it out a more suggested option? Is there any con to this approach that…

Is there a low-cost alternative to RJ45 cables for large number of signals?

We are designing two interface (printed) boards and need to connect them by cables (0.5-1.5m). So we're thinking about which connectors to use. We'd like to use twisted-pairs like in a RJ45 cable. The problem is, we are talking about 200 signals…

Crimping tool basics

When I design a printed circuit board, I often put 100mil male header anywhere. Sometimes I think it would be better to place some connectors for more reliability. Anyone here knows which connector/crimp/tool combination is good and cheap? I recall…

When wiring a European (Schuko) plug, what thing should I focus on not to mess up?

I know this might be a dumb question, as wiring a plug isn't some rocket science, but I am wondering if there is something not so obvious that can go wrong, or any tip at all for me to care when doing a cable assembly for a custom power extender…

Designing a cable tester

I need to check the integrity of 40+ custom cables. Each cable is meant to be the same, and is meant to have 19 ways. I bought an enclosure, some mating connectors, some LEDS and a bunch of resistors and diodes. My first and second attempts at…

Does a Connector With Multiple GND Pins Make a GND Loop?

There are some cable standards that have multiple GND pins on the connector proper. A good example of this is the SATA connector (it has 3 of them). In reality, each GND pin has a slightly different impedance, due to varying factors: connection…

What rules and tips make automated assembly easy?

What rules and tips make automated assembly easy, rather than unnecessarily difficult or completely impossible? In particular, if I have a circuit board that works fine after hand assembly, some people imply that they may not be suitable for…

Industry standard measure for coaxial cable stiffness?

Is there an industry standard measure for coaxial cable stiffness? By stiffness I mean the spring force experienced when bending or deforming the cable. In my search for a highly flexible lab test cable, I've been unable to find a standard…

Identify kind of cable with markings such as "WE-B 2 PAIR" on the jacket

While cleaning out our back yard shed, I came across a coil of cable of a kind that I have never seen before (image below). It was left here by the previous home owner, who worked in some kind of technical field. It has some unusual features. Other…

Disable data leads of USB cable

I've got a Sansa Clip that recharges via USB. Problem is that it "connects" to the PC whenever I plug it in. I learned a trick where you pull the cable out of the PC partially such that the data leads are no longer connected but the power leads…

"Correct" way to attach cable to this specific kind of banana plug

I bought a set of banana plugs of the style shown here (with rough 3d model to clarify the shape of the terminal because shiny metal is hard to photograph!). The site I got them from (here) didn't go into detail and there is no datasheet, plus I…
