Why Choose the Pizzato FD 20R2-L05F7M2 Safety Switch with Manual Mechanical Delay?
The Pizzato FD 20R2-L05F7M2 is a robust safety switch with manual mechanical delay and separate actuator designed for monitoring protective guards and access doors on industrial machinery. As part of the Pizzato FD series, it combines positive-opening safety contacts with a manually operated mechanical delay mechanism to help control access to hazardous machine areas.
This model features a long-knob 5 s manual mechanical delay, allowing an intentional waiting period before the guard can be opened. The B20 contact block provides 1NO + 2NC slow-action contacts, while the metal housing and positive-opening operation provide a durable solution for safety-related industrial applications.
The FD 20R2-L05F7M2 is equipped with a VF KEYF7 actuator adjustable in one direction and a single M20 × 1.5 threaded cable entry. With an IP67 protection rating, it is suitable for industrial machine guarding where dependable mechanical interlocking and delayed access are required.

Controlled Guard Access with Manual Mechanical Delay
Safety switches with manual mechanical delay are used where access to a hazardous machine area should not be immediate after an operating command. The mechanical delay requires the operator to intentionally turn the release mechanism and wait for the preset interval before opening the guard, providing time for hazardous machine movement to cease as part of a correctly designed safety system.
The Pizzato FD 20R2-L05F7M2 combines this 5 s mechanical delay with separate-actuator guard monitoring and positive-opening contacts. Its adjustable actuator facilitates installation on movable guards, while the rugged metal enclosure and IP67 protection support reliable service on industrial machinery.
Typical Applications
- Industrial machine guard doors and access gates.
- Machinery with hazardous movement requiring delayed access.
- Packaging and production machinery.
- Automated manufacturing equipment.
- Conveyors and material handling systems.
- Processing machinery and production cells.
- Industrial guarding requiring positive-opening safety contacts.
