Why Choose the Pizzato FR2257-W3M2 Limit Switch?
The Pizzato FR2257-W3M2 is a heavy-duty position / limit switch with reset function, engineered for precise motion detection and enhanced safety control in industrial automation systems. As part of the robust Pizzato FR series, it delivers dependable switching performance, long mechanical life and reliable operation in demanding environments.
This model features a roller lever actuator with a 20 mm technopolymer roller, ensuring smooth and repeatable actuation when interacting with moving machine components. Its durable technopolymer housing offers excellent resistance to dust, moisture and mechanical stress, making it ideal for harsh industrial conditions.
The FR2257-W3M2 is equipped with 2 normally open (NO) and 1 normally closed (NC) slow-action contacts and includes a simultaneous manual reset mechanism, ensuring safe and controlled restart after actuation. It features an M20 × 1.5 conduit entry without a cable gland for flexible installation across machinery and control panels.
