Why Choose the Pizzato FD 2899-F8K21 Safety Switch with Lock and Separate Actuator?
The Pizzato FD 2899-F8K21 is a robust safety switch with lock and separate actuator designed for monitoring and controlling access through movable guards on industrial machinery. Part of the Pizzato FD series, it combines guard position detection, mechanical locking and positive-opening safety contacts in a durable metal enclosure.
The FD 2899-F8K21 incorporates a 1NO + 1NC contact pair controlled by the lock plus 1NC contact controlled by the actuator (B28). This arrangement enables the safety system to monitor both the locking condition and actuator position, while positive-opening operation provides dependable mechanical opening of the relevant safety contacts.
The F8 configuration uses a universal separate actuator, providing installation flexibility for different guard arrangements. The K21 configuration provides key-operated auxiliary release, while the metal FD-series housing includes one PG 13.5 threaded cable entry and provides IP67 protection according to EN 60529.

Guard Locking with Separate Position and Lock Monitoring
Guard-locking safety switches are designed for machinery where a protective door or guard must be monitored and mechanically retained in its closed position. The separate actuator enters the switch head when the guard closes, allowing the switch to detect actuator position while the locking mechanism controls release of the guard.
The Pizzato FD 2899-F8K21 provides separate electrical monitoring functions for the actuator and lock through its B28 contact arrangement. When correctly integrated into an appropriate machine safety system, this enables dependable monitoring of guarded access points while the key-operated auxiliary release provides an additional method for releasing the locking mechanism when required by the installation.
Typical Applications
- Machine guard doors and protective enclosures.
- Automated manufacturing cells.
- Packaging and processing machinery.
- Industrial production and assembly equipment.
- Machine tools and automated machinery.
- Conveyors and material handling systems.
- Hinged and sliding movable guards.
- Industrial guard-locking and controlled-access systems.
