Why Choose the Pizzato FR3493-D7K25 Safety Switch?
The Pizzato FR3493-D7K25 is a high-reliability safety switch with separate actuator, engineered for industrial machine guarding and safety interlocking applications. As part of the robust Pizzato FR series, it ensures safe machine operation by detecting guard position and preventing hazardous movement when access points are open.
This variant features a D7 actuator configuration combined with a K25 connection interface, enabling fast installation and dependable electrical connectivity. The separate actuator design ensures that opening a guard physically disengages the actuator, forcing the safety contacts to open and immediately stopping the machine.
Built with a durable technopolymer housing and designed for long mechanical life, the FR3493-D7K25 provides consistent performance in demanding industrial environments. Its IP67 protection rating ensures reliable operation even in dusty or wet conditions.
Key Advantages
- Reliable safety switch with separate actuator for guard monitoring.
- Positive opening contacts ensure safe circuit interruption.
- D7 actuator design allows flexible installation on guards.
- K25 connection interface enables fast and secure wiring.
- Prevents machine restart when guards are open.
- Durable construction for harsh industrial environments.
Key Features
- Pizzato FR series safety switch.
- Separate actuator (D7 type) for guard interlocking.
- 2 normally closed (NC) contacts with positive opening.
- Slow-action switching mechanism for safety circuits.
- Technopolymer housing with high resistance.
- K25 connector for efficient electrical connection.

- Designed for safety and automation applications.
Reliable Guard Interlocking for Industrial Machinery
The FR3493-D7K25 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.
This mechanism is essential in industrial safety systems, helping protect operators, reduce risk and ensure compliance with machinery safety regulations across automated environments.
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.
