Why Choose the Pizzato FR2231-W3M2 Safety Limit Switch?
The Pizzato FR2231-W3M2 is a heavy-duty safety limit switch with manual reset, designed for precise position detection and controlled restart in industrial automation systems. As part of the proven Pizzato FR series, it is engineered for applications where safety, reliability and operator-controlled reset are critical.
This model features a roller lever actuator with an 18 mm technopolymer roller, ensuring smooth and repeatable actuation when interacting with moving machine components. It is equipped with a 2 NO + 1 NC contact configuration with positive opening operation, providing safe and dependable switching for safety circuits and control systems.
The integrated simultaneous manual reset mechanism ensures that the switch must be deliberately reset after actuation, preventing unintended machine restart. With a rugged technopolymer housing, M20 x 1.5 conduit entry, and IP67 protection rating, the FR2231-W3M2 is well suited for demanding industrial environments.
