Why Choose the Pizzato FR651-M1 Limit Switch?
The Pizzato FR651-M1 is a robust industrial limit switch with roller lever, designed for accurate position detection and controlled switching in industrial automation systems. As part of the proven Pizzato FR series, it offers dependable performance in demanding environments where reliability and consistency are essential.
Built with a durable technopolymer housing and precision mechanical components, the FR651-M1 ensures smooth actuation and long operational life. Its slow-action contact system (1 NO + 1 NC) provides stable switching behaviour, making it ideal for applications where controlled signal transitions are required rather than fast snap-action switching.
With high ingress protection and a compact design, this limit switch is well suited for harsh industrial environments, including exposure to dust, moisture and vibration.
