Why Choose the Pizzato FR593-K21 Safety Switch?
The Pizzato FR593-K21 is a reliable safety switch with separate actuator, designed for machine guarding and industrial safety applications. As part of the well-established Pizzato FR series, it ensures safe operation by detecting guard position and interrupting control circuits when access points are opened.
This version features a K21 connector interface, allowing fast and secure electrical connection without the need for conventional cable glands. The separate actuator mechanism ensures that when the guard is opened, the actuator disengages, forcing the safety contacts to open and immediately stopping machine operation.
Constructed with a robust technopolymer housing, the FR593-K21 offers high mechanical durability and long service life. With an IP67 protection rating, it is suitable for industrial environments exposed to dust, moisture and vibration.

Key Features
- Pizzato FR series safety switch.
- K21 connector interface for fast installation.
- Separate actuator operation for guard interlocking.
- 1 normally open (NO) + 1 normally closed (NC) contact.
- Snap-action switching mechanism.
- Positive opening NC contact for safety circuits.
- Technopolymer housing for durability.
- IP67 protection rating.
Reliable Guard Interlocking for Industrial Machinery
The FR593-K21 operates by separating the actuator from the switch body when a guard is opened. This ensures positive opening of the safety contacts, immediately stopping machinery and preventing restart until the guard is securely closed.
Safety switches with separate actuators are essential in modern industrial safety systems, helping protect personnel, reduce operational risk and ensure compliance with machinery safety regulations.
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.
- OEM machine building and safety integration.
