FK 3393-E3D8M1 Pizzato Safety switch with separate actuator

Why Choose the Pizzato FK 3393-E3D8M1 Safety Switch?

The Pizzato FK 3393-E3D8M1 is a compact and robust safety switch with separate actuator designed for monitoring movable guards, doors and protective access points on industrial machinery. As part of the established Pizzato FK Series, it combines mechanical guard position detection with positive-opening safety operation for dependable integration into industrial machine safety systems.

The FK 3393-E3D8M1 uses a universal separate mechanical actuator that operates the switch as the associated protective guard opens and closes. Its B33 slow-action contact block provides 1NO + 1NC contacts, allowing the normally closed contact to perform the safety switching function while the normally open contact can be used for auxiliary guard status signalling.

Designed for demanding industrial environments, the FK 3393-E3D8M1 features a durable technopolymer housing, a threaded M16 × 1.5 cable entry and high ingress protection. The enclosure provides IP67 protection according to EN 60529 together with IP69K protection according to ISO 20653, making this configuration suitable for machine builders requiring a compact and resilient guard monitoring solution.

Reliable Guard Monitoring for Industrial Machinery

Separate-actuator safety switches are used to monitor protective guards surrounding hazardous machinery. When a monitored guard opens, the mechanical actuator is withdrawn from the switch head and the safety contacts change state, allowing the connected safety system to stop hazardous movement or prevent machinery from restarting while access remains open.

The Pizzato FK Series provides a compact mechanical solution for this type of guard monitoring. The FK 3393-E3D8M1 combines a universal actuator with slow-action 1NO + 1NC contacts, positive-opening operation and a highly protected technopolymer enclosure, making it suitable for reliable integration into modern machinery and industrial automation systems.

Typical Applications

• Machine guard doors and protective access panels.
• Automated production and assembly machinery.
• Packaging and processing equipment.
• Robotic cells and automated manufacturing systems.
• Conveyor and material handling equipment.
• Machine tools and industrial production machinery.
• Hinged, sliding and removable protective guards.
