Why Choose the Pizzato FC3493 Safety Interlock Switch?
The Pizzato FC3493 is a robust key-operated safety interlock switch designed for machine guarding, access control, and industrial safety systems. As part of the Pizzato FC series, it is engineered to ensure that machinery can only operate when protective guards, doors, or access panels are securely closed.
Built for harsh industrial environments, the FC3493 features a durable metal housing and a high IP67 protection rating, ensuring resistance against dust, moisture, and vibration. It is widely used in automation systems, production machinery, and safety enclosures where reliable guard monitoring is required to protect operators and equipment.
The FC3493 is the 2NC safety contact version of the FC3393 family, providing redundant safety switching for higher integrity safety circuits. This makes it suitable for applications requiring dual-channel safety monitoring and enhanced fault detection.
Key Advantages
- High-integrity dual NC safety contact configuration (2NC).
- Reliable key-operated interlock system for machine guarding.
- Prevents machine operation when guards are open.
- Heavy-duty metal housing for industrial durability.
- IP67 protection rating against dust and water ingress.
- Suitable for safety-rated PLC and dual-channel safety circuits.
Key Features
- Pizzato FC safety switch series.
- Key-operated interlock mechanism (8 key positions).
- Contact configuration: 2NC (slow action).
- Positive opening safety contacts.
- IP67 protection rating according to EN 60529.
- Metal housing construction for industrial environments.
- M20 x 1.5 threaded electrical entry.
Reliable Machine Guard Protection
The FC3493 operates using a key-based safety interlock mechanism installed on machine guards or access doors. When the guard is closed and the key mechanism is engaged, machine operation is enabled. When the guard is opened or the key is removed, both NC safety contacts open, immediately triggering a safe stop condition.
This dual-channel configuration increases safety reliability and is commonly used in safety circuits requiring redundancy and fault detection.
Typical Applications
- Machine guarding systems.
- Safety doors and access panels.
- Industrial automation equipment.
- Robotic cells and fenced areas.
- Packaging and processing machinery.
- OEM safety-rated machine systems.
