2PCS DB9 Solderless Connector, RS232 D-SUB Serial to 9-Pin Port Terminal Female Adapter Connector Breakout Board with Locking Housing

I have used a bunch of these and they are all fine. Easy to assemble. They smell pretty bad though coming out of the packaging.

The pin numbers and GND silkscreen on the board were very helpful keeping track of which wire goes where. In my application Roboteq HDC-2460 motor controller I was unable to use the 25 pin and 9 pin connectors side by side with the shells on due to the narrow spacing between connectors. I was able to use them by removing both backshells.

Everything you need to make a fully functional DB9, in my case for custom loopback connectors.

I have not used the connectors yet but they appear to be a good product,

Excelente producto, calidad y precio
