DB9 母頭連接器 金屬外殼 RS232 轉接器 藍色塑膠核心

Bought two of these for a home automation project and the blue plastic core makes it easy to tell the gender at a glance while wiring. The metal housing feels sturdy enough to handle repeated plugging and unplugging without any wiggle.

The metal housing feels solid right out of the bag, and the blue core seats snugly when I plug it into my serial cables. I've had cheap plastic ones crack before, but this one's got that shielding and durability I was hoping for.

The blue plastic core makes lining up the pins a lot easier than those all-metal ones I've wrestled with before. Solid build for the price, just wish the screws came a tiny bit tighter from the factory.
