Why Choose the Pizzato FR593-E3D2K21 Safety Switch?
The Pizzato FR593-E3D2K21 is a high-reliability safety switch with separate actuator, designed for machine guarding and industrial safety systems. As part of the proven Pizzato FR series, it ensures safe operation by detecting guard position and interrupting control circuits when protective doors or panels are opened.
This version combines an E3D2 jointed actuator with a K21 connector interface, providing both flexible mechanical alignment and rapid electrical installation. When the guard is opened, the actuator disengages from the switch body, forcing the safety contacts to open and immediately stopping machine operation.
Constructed with a durable technopolymer housing and engineered for long mechanical life, the FR593-E3D2K21 delivers dependable performance in demanding industrial environments. With an IP67 protection rating, it is suitable for applications exposed to dust, moisture and vibration.
Key Advantages
- Reliable safety switch with separate actuator for guard monitoring.
- Positive opening contacts ensure safe circuit interruption.
- Jointed actuator design allows flexible installation alignment.
- K21 connector enables quick and secure wiring.
- Compact, robust construction for industrial environments.
- Prevents machine restart when guards are open.
Key Features
- Pizzato FR series safety switch.
- Separate actuator (E3D2 jointed type).
- K21 connector interface for rapid installation.
- 1 normally open (NO) + 1 normally closed (NC) contact.
- Snap-action switching mechanism.
- Positive opening NC contact for safety circuits.
- Technopolymer housing with high mechanical resistance.
- IP67 protection rating for dust and water resistance.
Reliable Guard Interlocking for Industrial Machinery
The FR593-E3D2K21 operates by separating the actuator from the switch body when a guard is opened. This 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 personnel, reduce risk and ensure compliance with machinery safety regulations.
Typical Applications
- Machine guarding and safety interlocking systems.
- Industrial automation and production lines.
- Conveyor systems and material handling equipment.
- Packaging and processing machinery.
- Robotics and automated manufacturing systems.
- OEM machine building and safety integration.
