The Pizzato FR3393-E3 is a robust and reliable safety switch with separate actuator, engineered for precise position monitoring and machine safety in industrial automation systems. As part of the proven Pizzato FR3393 series, it delivers dependable switching performance in safety-critical applications where durability and compliance are essential.
This model features a strong technopolymer housing with a single PG13.5 threaded conduit entry, providing excellent resistance to mechanical stress and demanding industrial environments. It incorporates positive opening safety contacts, ensuring guaranteed circuit interruption even in the event of contact welding or failure.
With a 1 NO + 1 NC slow-action contact configuration and a non-detachable head, the FR3393-E3 is ideal for machine guarding, access control and automated production systems requiring reliable safety feedback and long-term performance.
Safety switches such as the FR3393-E3 are designed to monitor guard doors, gates and moving machine components. When the actuator is removed or disengaged, the switch interrupts the safety circuit, ensuring immediate shutdown of hazardous machine movement to protect personnel and equipment.
The 1 NO + 1 NC configuration provides both safety interruption and auxiliary signalling, making it suitable for integration into modern automation systems where monitoring and control feedback are required.
