This connector pack comes with five 3.5mm (MH-FC) bullet connectors and five 3.5mm (FH-MC) connectors. These are the same connectors as found on the Yellow Jacket Planetary Gear Motors. They provide a reliable connection in a compact form-factor for wires up to 16AWG. This style of connector is great for applications, such as a motor, where you may want to reverse polarity by changing where the wires plug in.
MH-FC = Male Housing, Female Contact
FH-MC = Female Housing, Male Contact
