Binder connectors used by Aim for their data loggers and dashes come in 2 varations.
The completely plastic 719 series is used as a 3 way on some older kart systems. The 4 way is used on many sensors and extension leads.
The 712 has a metal screw locking mechanism. The 3 way is used on karts for water temperature. The 4 way is used extensively for connecting sensors to logging systems. The 5 way is generally a communication channel such as CAN or serial. The 7 and 8 way were used on the older XG Log data logger.
To describe them as male or female is confusing as they typically a male housing with female sockets. So like military connectors we describe the orientation of the contacts as the important feature, the housing is secondary.
