Why Choose the Pizzato FK 3493-E3D3 Safety Switch with Separate Actuator?
The Pizzato FK 3493-E3D3 is a compact and dependable FK series safety switch with separate actuator designed for monitoring movable machine guards, access doors and protective covers in industrial machinery. Its separate-actuator operating principle allows the switch to detect when a guard is opened, helping the associated safety control system stop or inhibit hazardous machine functions.
This version combines a durable technopolymer housing with a 2NC slow-action B34 contact block and positive-opening operation. The E3 option increases actuator extraction force to 30 N, providing greater resistance to accidental actuator withdrawal than the standard FK series configuration.
The D3 actuator is adjustable in two directions, providing flexibility when aligning the switch and actuator on hinged or sliding guards. With IP67 and IP69K protection, the FK 3493-E3D3 provides a reliable solution for industrial machine safety applications exposed to dust, moisture and demanding operating conditions.

Reliable Machine Guard Monitoring
The Pizzato FK 3493-E3D3 monitors machine guard position by using a separate actuator mounted to the movable guard. When the guard is closed, the actuator enters the switch head; when the guard opens, withdrawal of the actuator mechanically operates the safety contacts so the machine control system can respond appropriately.
The adjustable D3 actuator helps accommodate installation geometry and alignment requirements, while the E3 high-extraction-force option provides additional resistance against unintended actuator withdrawal. Combined with positive-opening contacts and robust environmental protection, this makes the FK 3493-E3D3 suitable for reliable industrial guard interlocking.
