Allen-Bradley 163K434H01 Safety Interlock Switch

Description:

The 163K434H01 Non-Defeatable Plunger Interlock Switch is used in industrial safety systems to monitor guard doors, access panels, and machine enclosures while preventing equipment operation when safety barriers are open. Commonly installed in automated machinery, conveyor systems, packaging equipment, manufacturing cells, and industrial processing equipment requiring personnel protection and machine safeguarding. Maintenance teams and system integrators use this switch for repair, retrofit, expansion, or replacement of existing safety interlock devices to maintain compliance with machine safety requirements. The switch features a non-defeatable plunger design and a 3-connector configuration for secure safety circuit integration.

Applications:

The 163K434H01 Non-Defeatable Plunger Interlock Switch is commonly used on machine guards, access doors, safety gates, protective covers, and equipment enclosures where hazardous motion must be prevented when operator access is possible. The plunger-actuated mechanism changes state when a guard or door is opened, allowing safety relays and control systems to stop or inhibit machine operation. Non-defeatable interlock switches are widely utilized in industrial environments to improve operator safety and support machine safeguarding programs.
