Why Choose the Pizzato FR22C2-K21 Safety Limit Switch?
The Pizzato FR22C2-K21 is a heavy-duty safety limit switch with positive opening, engineered for reliable position detection and fail-safe monitoring in industrial automation systems. As part of the rugged Pizzato FR series, it delivers consistent switching performance and long-term durability in demanding environments.
This model is equipped with a straight slotted hole lever actuator, enabling flexible adjustment and precise alignment with moving machine components. Its robust technopolymer housing with external gasket sealing provides strong resistance to dust, moisture and mechanical stress, ensuring dependable operation in harsh industrial conditions.
Featuring a 2NC + 1NO slow-action contact configuration, the FR22C2-K21 is optimised for redundant fail-safe safety circuits. The integrated positive opening mechanism ensures that normally closed contacts are mechanically forced open even in fault conditions such as contact welding, providing enhanced safety in critical applications.
Key Advantages
- Certified positive opening mechanism for fail-safe operation.
- 2 normally closed + 1 normally open contacts for redundant safety circuits.
- Slotted hole lever actuator for adjustable positioning.
- Durable technopolymer housing for industrial environments.
- IP67 protection rating for dust and water resistance.
- Reliable and repeatable switching performance.
