PS 2 cable assemblies enable mice and keyboard connections to compatible computer systems. The cable assembly fits into the PS 2 port, which is a six pin mini-DIN connector.
PS 2 cable assemblies are made from PVC materials with aluminium foil screenings on the inside. PS 2 cable assemblies can be either shielded (single insulation) or double shielded (two insulation layers), to increase strain relief and cable protection.
The PS 2 interface designs are electrically similar, and the cable assemblies are distinguished by green colouring for mice and purple for keyboard connection ports.
PS 2 cable assemblies were previously used to connect mice and keyboards to computers from the IBM Personal System/2 series. They have since been replaced with USB
In the manufacturing and production industries, PS 2 cable assemblies are still used to connect mice or keyboards to switch boxes and multiplexors. They are also used in data centres with switching applications where one keyboard, mouse and monitor combination controls multiple computers simultaneously.
Types of PS 2 cable assemblies include mice cables, keyboard cables and extension cables.
