The PS/2 interface is a standard developed by IBM to connect keyboards and mice to computers. It was widely used in PCs before USB became the dominant connection type. It features a 6-pin mini-DIN connector and provides a direct, dedicated link for input devices.

Although less common in consumer devices today, the PS/2 interface is still widely used in industrial, legacy, and military environments where long-term stability and compatibility are essential.

What are PS/2 connectors and adapters used for?

PS/2 adapters offer a stable connection for keyboards and mice, and allow you to:

• Connect PS/2 keyboards and mice to PS/2 or USB ports using bidirectional adapters.
• Maintain full functionality of legacy devices, avoiding compatibility issues.
• Ensure more direct, lag-free input compared to some USB devices in critical environments.

Where are they used?

Essential in industrial and technical settings, PS/2 connectors remain indispensable for applications such as:

• Industrial machines and embedded systems that require PS/2 input.
• Legacy systems that do not support USB or where USB is disabled for security reasons.
• Environments requiring system boot without USB drivers, such as BIOS or emergency modes.

Why should you use PS/2 in your business?

Many technical and business environments require proven hardware compatible with legacy systems.

Using PS/2 connectors means:

• Avoiding obsolescence of current devices.
• Extending the service life of industrial PCs, diagnostic tools, or control machines.
• Ensuring direct interaction with the OS or firmware without relying on external drivers or software.
