Pizzato Elettrica FR 693-E3M2 — Safety Switch with Separate Actuator, FR Technopolymer Housing, 1NO+1NC Slow Action, M20×1.5 Conduit Entry, 30 N Actuator Extraction Force, IP67. A compact safety interlock switch designed for controlling gates, sliding doors, and guards protecting dangerous machine parts without inertia. The stainless steel actuator separates from the switch each time the guard opens, forcing positive opening of the electrical contacts — and the machine can only be restarted after the guard is closed. Rated up to SIL 3 / PL e for safety-critical applications.
