JUXINICE 2PCS DB9 Female adapters, Easy to useDIY RS232/485 Serial Cable, No Soldering Needed DB9 Serial connectors with Bolts Nuts Tail Pipes and Screwdriver

I bought these to make radio programming cables that run anywhere from $100-300 on eBay due to scarcity. With these adapters, I was able to use standard hookup wire with pogo pins and a 3d printed connector. Because these have terminals, I could adujst what pins were used, which helped in a case where I had conflicting pin-outs. The multiple sleeve adapters are nice too, because some of what I built had as few as 3 wires inside, but others had 8. Good value overall, and the terminals are a major plus

These are very sturdy, robust, and do the job very well. The inclusion of the several sizes of strain relief gives these a very finished look when assembled.Due to the way these are constructed to handle either having anchor screws or being screwed into means their holes are continuously threaded. As a consequence, if using with screws, they thread in and out of the holes rather than remaining loose but captive. Make sure the screws are retracted all the way before plugging in and screwing down to ensure full engagement of the connector.
