£21.95
The Pizzato FR21C2 is a heavy-duty industrial safety switch with slotted-hole lever actuation designed for monitoring hinged guards, machine doors, and protective access panels in automation systems. Manufactured by Pizzato Elettrica, it delivers reliable safety signalling when a guard is opened, ensuring immediate machine shutdown and improved operator protection.
As part of the robust FR series safety switch family, the FR21C2 is engineered for demanding industrial environments requiring high mechanical durability, stable switching performance, and strong resistance to dust, water, vibration, and industrial wear. It is widely used in OEM machinery, conveyors, packaging systems, and automated production lines.
The FR21C2 belongs to the “21C2” configuration group, typically used in safety interlock circuits requiring triple normally closed contacts (3NC) for redundant safety monitoring in high-integrity machine guarding applications. {index=1}
The Pizzato FR21C2 ensures safe machine operation by detecting guard or lever movement and immediately triggering safety circuits. This prevents unintended machine start-up and protects operators during maintenance, setup, and access operations.
Based on Pizzato FR series catalogue data, the FR21C2 is part of the 21C2 configuration featuring 3NC contacts, commonly used in high-integrity safety interlock systems requiring multiple redundant safety channels. The FR series is designed with IP67 protection, high mechanical endurance, and positive opening contacts compliant with EN 60947-5-1. (source) {index=2}
