Why Choose the Pizzato FR3493-D11 Safety Switch?
The Pizzato FR3493-D11 is a durable and reliable safety switch with separate actuator, designed for industrial machine guarding and safety interlocking applications. As part of the proven Pizzato FR series, it ensures that machinery operates only when protective guards are securely closed.
This model utilises a separate actuator mechanism, where the actuator is mounted on the guard and the switch body on the machine frame. When the guard is opened, the actuator disengages, forcing the safety contacts to open and immediately stopping the machine.
Constructed with a robust technopolymer housing and designed for high mechanical endurance, the FR3493-D11 is ideal for demanding industrial environments. Its compact form and IP-rated enclosure ensure long-term reliability and consistent safety performance.
Key Advantages
- Reliable safety switch with separate actuator for guard monitoring.
- Positive opening contacts for safe circuit interruption.
- Prevents machine restart when guards are open.
- Durable construction for harsh industrial environments.
- Flexible installation on safety doors and access panels.
- Suitable for integration into high-performance safety systems.
Key Features
- Pizzato FR series safety switch.
- Separate actuator (D11 type) for guard interlocking.
- 2 normally closed (NC) contacts for safety circuits.
- Positive opening operation.
- Technopolymer housing with high resistance.
- Cable entry (PG type) for standard wiring.
- Compact and rugged industrial design.
- Designed for machine safety and automation systems.
Reliable Guard Interlocking for Industrial Machinery
The FR3493-D11 operates by mechanically separating the actuator from the switch body when a guard is opened. This action forces the positive opening of the safety contacts, ensuring that machinery stops immediately and cannot restart until the guard is securely closed.
This makes it an essential component in machine safety systems, helping to reduce risk, improve operator protection and ensure compliance with industrial 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.
