Our male PS/2 (MiniDin6) cable is designed to work with keyboards and mice that utilize the MiniDin6 connector. Before the USB connection established its dominance connecting devices to a computer, the PS/2 connector was the primary method to secure a mouse or keyboard. To extend a PS/2 mouse or PS/2 keyboard that have a built in PS/2 cable with this, you would need a PS/2 coupler. This PS/2 cable can also be used to connect a computer to a PS/2 KVM switch if you are controlling multiple computers with a single monitor, keyboard and mouse.
