Why Choose the Pizzato FS3096D024-FK21 Safety Switch?
The Pizzato FS3096D024-FK21 is a robust safety interlock switch with solenoid locking and key-operated release, designed for secure guard monitoring and controlled access in industrial machinery. As part of the proven Pizzato FS series, it ensures that safety doors remain locked during operation, preventing access to hazardous areas and improving operator safety.
This model operates with a 24 V AC/DC solenoid and uses a de-energised locking principle, meaning the actuator remains locked when power is removed. This fail-safe behaviour ensures safety is maintained even during power loss or emergency stop conditions, making it ideal for safety-critical industrial environments.
The FS3096D024-FK21 variant includes a key-operated manual release (K21), allowing authorised personnel to unlock the guard when required for maintenance or emergency access. Combined with its rotating head and rugged technopolymer housing, it offers flexibility and durability in demanding industrial applications.
Key Advantages
- Safety interlock with solenoid locking for controlled access to hazardous areas.
- 24 V AC/DC operation compatible with industrial control systems.
- Fail-safe locking (power-to-release) ensures maximum safety integrity.
- Key-operated release (K21) for authorised manual unlocking.
- Prevents machine operation when guards are open.
- Durable construction for long-term industrial reliability.
Key Features
- Pizzato FS series safety interlock switch.
- Model: FS3096D024-FK21.
- Solenoid locking mechanism with 24 V AC/DC supply.
- Contact configuration: 2 NC (actuator) + 1 NC (solenoid).
- Key-operated manual release (K21) for maintenance access.

Secure Guard Locking with Controlled Manual Release
The FS3096D024-FK21 ensures that machinery cannot operate unless guards are securely closed and locked. Its fail-safe locking mechanism prevents unintended access during power outages or emergency stop conditions, maintaining a safe working environment at all times.
The integrated key-operated release provides controlled manual override, allowing authorised personnel to unlock the guard for maintenance or servicing without compromising overall system safety.
Typical Applications
- Machine guarding and safety door interlocking.
- Industrial automation and robotic systems.
- Packaging and processing machinery.
- Conveyor and material handling systems.
- CNC machines and industrial equipment.
- Maintenance-access controlled safety systems.
