Why Choose the Pizzato FR593-E3 Safety Switch?
The Pizzato FR593-E3 is a rugged safety switch with separate actuator, designed to provide reliable guard monitoring and machine safety in industrial environments. As part of the proven Pizzato FR series, it ensures safe operation by detecting guard position and interrupting control circuits when access points are opened.
This version features an E3 actuator configuration, offering a compact and reliable engagement solution for standard guard interlocking applications. The separate actuator mechanism ensures that when a guard is opened, the actuator disengages, forcing the safety contacts to open and immediately stopping machine operation.
Built with a robust technopolymer housing, the FR593-E3 is designed for long mechanical life and dependable performance in demanding industrial environments. With an IP67 protection rating, it provides excellent resistance to dust, moisture and vibration, making it suitable for a wide range of industrial applications.

Reliable Guard Interlocking for Industrial Machinery
The FR593-E3 operates by separating the actuator from the switch body when a guard is opened. This action forces the positive opening of the safety contacts, ensuring machinery stops immediately and cannot restart until the guard is securely closed.
Safety switches with separate actuators are essential components in modern industrial safety systems, helping protect operators, reduce risk and ensure compliance with safety standards across manufacturing and automation environments.
Typical Applications
- Machine guarding and safety interlocking systems.
- Industrial automation and production lines.
- Conveyor and material handling systems.
- Packaging and processing machinery.
- Robotics and automated manufacturing cells.
