Why Choose the Pizzato FD 22R2-F8M2 Safety Switch with Manual Mechanical Delay?
The Pizzato FD 22R2-F8M2 is a robust safety switch with manual mechanical delay and separate actuator designed for controlled access to guarded areas of industrial machinery. Part of the Pizzato FD series, it combines a metal housing, three slow-action contacts and positive-opening safety operation with a mechanical delayed-release mechanism.
The FD 22R2-F8M2 incorporates a 2NO + 1NC slow-action contact configuration and a manual mechanical delay mechanism with a nominal 20 s delay. This arrangement provides a normally closed positive-opening safety contact together with two normally open contacts, making the switch suitable for guard monitoring applications that also require auxiliary signalling functions.
The F8 configuration uses the Pizzato VF KEYF8 universal separate actuator, while the M2 configuration provides a single M20 × 1.5 threaded conduit entry. Combined with its rugged metal construction, the FD 22R2-F8M2 provides a durable mechanical safety solution for machine guards where access should be deliberately delayed following a stop command.
Key Advantages
- Manual mechanical delay provides controlled access to guarded machinery.
- Nominal 20 s delay provides additional time before the guard can be released.
- 2NO + 1NC slow-action contacts provide safety switching and auxiliary signalling capability.
- Positive-opening NC contact supports dependable mechanical interruption of the safety circuit.
- VF KEYF8 universal actuator provides installation flexibility for movable machine guards.
- Robust metal FD-series housing is designed for demanding industrial environments.
- M20 × 1.5 threaded conduit entry supports standard industrial cable installation.

Controlled Access for Machinery with Residual Hazards
Manual mechanical delay safety switches are particularly useful on machinery where hazardous movement may continue for a period after a stop command. The mechanical delayed-release mechanism introduces a defined period before the separate actuator can be released, helping provide time for residual movement to cease before an operator gains access through the monitored guard.
The Pizzato FD 22R2-F8M2 combines this delayed-access principle with a universal separate actuator and a three-contact slow-action arrangement. When correctly selected, installed and integrated into an appropriate machine safety system, it provides reliable guard monitoring together with controlled access for industrial machinery.
Typical Applications
- Machine guard doors and protective enclosures.
- Machinery with residual movement after a stop command.
- Machine tools and rotating machinery.
- Packaging and processing equipment.
- Industrial production and assembly machinery.
- Automated manufacturing cells.
- Conveyors and material handling equipment.
- Industrial safety interlocking and controlled-access systems.
