The cable was flexible and easy to handle. However, as it is a cable for communication with the old NC machine by RS232C, I thought that it was better to narrow the signal line a bit more. It was slightly thicker at 0.3 SQ, but it was a little hard to solder to the RS232C terminal. But it was good as we could procure the necessary length at an affordable price.
When I first used it, I was worried about strength, because it was thinner than I thought, but it did not matter. Conventionally, the VFF 2 core wire is used and malfunction occurred due to power supply noise, but instead of this, the malfunction ceased to exist
