What is an example of an interlock guard?

An example of an interlock guard is a safety gate on a robotic work cell:

• If the safety gate is opened, the interlock switch triggers, causing the robotic system to immediately shut down to prevent worker contact with moving parts.
• The machine cannot restart until the gate is securely closed and the system is reset.

Other examples include:

• Interlocked covers on presses or CNC machines.
• Access doors with interlocks on conveyor systems.

These guards ensure machines operate only when all safety conditions are met.
