Why Choose the Pizzato FD 6R2-L10F1M2 Safety Switch with Manual Mechanical Delay?
The Pizzato FD 6R2-L10F1M2 is a robust safety switch with manual mechanical delay and separate actuator designed for controlled access to industrial machinery where hazardous movement may continue after a stop command. Part of the Pizzato FD Series, it combines mechanical guard locking, positive-opening safety contacts and a deliberately timed manual release mechanism in a rugged metal enclosure.
The FD 6R2-L10F1M2 features a 1 NO + 1 NC slow-action contact configuration and an L10 long-knob mechanical delay of approximately 10 seconds. During the release sequence, the safety contact is positively opened before the guard actuator can be withdrawn, helping provide a defined period for residual machine movement to stop before access is permitted.
The F1 configuration uses the Pizzato VF KEYF1 angled actuator, while the M2 suffix specifies a single M20 × 1.5 threaded conduit entry. With its metal FD housing, IP67 protection according to EN 60529 and standard operating temperature range of -25 °C to +80 °C, the FD 6R2-L10F1M2 provides a dependable mechanically delayed guard-access solution for demanding machinery.
Key Advantages
- Complete safety switch with manual mechanical delay and separate actuator.
- L10 long-knob mechanism provides an approximately 10-second delay before actuator release.

Controlled 10-Second Access Delay for Industrial Machinery
Industrial machinery containing flywheels, cutting tools, pulleys, shafts and other moving components can remain hazardous after a stop command has been issued. The Pizzato FD 6R2-L10F1M2 addresses this requirement with a manually operated mechanical sequence that first opens the safety contact and then delays release of the guard actuator for approximately 10 seconds.
Because the delayed-release function is mechanical, it does not depend on an electronic timing circuit or electrical supply for the delay itself. This makes the FD 6R2-L10F1M2 particularly suitable for machinery with a known run-down period where a simple, robust and predictable means of controlling guard access is required.
Typical Applications
- Industrial machinery with predictable residual or run-down movement.
- Machine guard doors requiring mechanically delayed access.
- Machinery incorporating flywheels, pulleys and rotating shafts.
- Sawing, cutting and processing machinery.
- Mills, mixers and mechanically driven production equipment.
- Packaging and manufacturing machinery.
- OEM machinery and industrial safety systems.
