MH Connectors offers a variety of data connectivity options, including their Cat 6 shielded Ethernet plug MHRJC6AR2421. Depictions of this product show an empty boot; is this just a shell? What does this part number ship with?
Per the product’s datasheet, the device comes with the connector housing, the boot, a load bar, and two different prongs. It does not come with a cable clamp, however. If you need extra strain relief, you may wish to investigate alternative options.
