2Packs DB9 Serial Adapters No Soldering Needed. D-SUB 9-pin RS232 RS485 Adapter to Terminal Connector Signal Module with Bolts Nuts and Screwdriver (1PCS Male+1PCS Female)

Perfect ,

All 5 connectors had one or two screws that did not tighten against the wire. It seems they are stuck and it does not matter if screw it or out they will not move

Es muy práctico y ahorra tiempo en comparación con los modelos de soldadura.

I needed a serial cable with a very specific wiring arrangement, these ends were easy to work with and they did a great job. The kit even supplied a small screwdriver for landing and tightening connections. This was a low cost solution to solve a connectivity problem. They are not the most compact ends in the world, but they do the job nicely.

Well made and the connections are very solid. Look at them to see how to use them. They are closed when shipped so you have to open them first. Well marked and have a clever cover that completely secures covers the connections. Well worth the cost.

I use these in a ham radio application and they work well. They fit right but I wish the case was a little lower profile. Good value for sure. I'll buy them again when needed.
