Why Choose the Pizzato FD 20R2-L05FM2 Safety Switch with Manual Mechanical Delay?
The Pizzato FD 20R2-L05FM2 is a robust safety switch with manual mechanical delay and separate actuator designed for controlled access to hazardous areas of industrial machinery. Part of the proven Pizzato FD safety switch series, it combines mechanical guard monitoring with a manually operated delay mechanism, helping ensure that access to a protected area follows the required machine stopping procedure.
The FD 20R2 family uses a 1NO + 2NC slow-action contact arrangement with positive-opening safety contacts. The manual mechanical delay requires deliberate operator action before the actuator can be released, making this type of switch particularly useful where access to machinery should not be immediate after a stop command.
The FD 20R2-L05FM2 combines the FD series' rugged metal construction with IP67 protection and an M20 × 1.5 threaded cable entry. Its separate-actuator design is suitable for movable machine guards and access doors in production machinery, automated equipment and other demanding industrial safety installations.
Key Advantages
- Combines guard monitoring with a manual mechanical access delay.
- 1NO + 2NC slow-action contacts provide safety and auxiliary signalling functions.
- Positive-opening safety contacts support dependable interruption of safety circuits.
- Separate actuator provides direct mechanical monitoring of the protective guard.
- Rugged metal FD-series enclosure with IP67 protection.
- M20 × 1.5 threaded cable entry supports conventional industrial field wiring.

- IP67 protection rating according to EN 60529.
- M20 × 1.5 threaded cable entry.
Reliable Manual-Delay Guard Interlocking for Industrial Machinery
Safety switches with manual mechanical delay are designed for applications where opening a protective guard should involve a deliberate sequence rather than immediate actuator release. The mechanical delay provides additional time between initiation of the release procedure and access to the protected machine area, making the arrangement useful for machinery with stopping processes that must be considered before entry.
The Pizzato FD 20R2-L05FM2 combines this function with separate-actuator guard monitoring and positive-opening safety contacts. Its rugged metal enclosure and IP67 protection make it well suited to industrial automation systems requiring durable mechanical safety interlocking without dependence on an electrically operated locking solenoid.
Typical Applications
- Machine guards requiring controlled access.
- Automated manufacturing and assembly cells.
- Packaging and processing machinery.
- Machine tools and production equipment.
- Conveyor and material handling systems.
- Industrial machinery with hazardous run-down or stopping sequences.
