These solid 1.25mm pitch connector cable pairs are great when you need something that can carry a couple amps of current and are easy to connect and disconnect.
These cables are nice and long, 10cm each, in fact. They've got both small form-factor and are a matching set, with an inline socket and plug connector. The two friction lock to make easy-breezy connections whenever you need light and small connectivity.
The two cables match with each other and with any Molex PicoBlade compatible connectors.
