5PCS DB25 Solderless Connector, RS232 D-SUB Serial to 25-pin Port 16mm Thinner Terminal Male Adapter Breakout Board with Case Long Bolts Nuts

Years ago, I had to solder custom DB25 connectors from time to time. I thought the idea of screw terminals (new to me) would be a real boon. The Ambits includes all the pieces you need to create a tight and secure connector. The build quality is very good and when complete, it passed my continuity test first try. This was only four wires, so I figured this would be a quick build. However, there is something of a learning curve involved. First, the wire ends need to be trimmed and tinned. This connector was split out into two different wires, and I forgot that only the thin (22gague) internal wires can be exposed, but the insulation needs to be placed under the clamp. Also, the terminal arrangement with two blocks at 90º make it hard if your wires need to go into the corner. So, for this few wires, I’m not sure if a traditional solder connector would have been better. But as a screw-type, I think this is the best of the lot.
