When 0.1″ is too big, and JST PH’s too chunky, these ultra-slim 1.25mm connectors are a reliable alternative. These are only 1.25mm pitch, but have a nice clicky connection.
These cables are nice and long, 40cm 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.
