Why Choose the Pizzato FD2018-K21 Position Switch?
The Pizzato FD2018-K21 is a heavy-duty industrial position / limit switch engineered for precise and reliable detection of mechanical movement in demanding automation environments. As part of the robust Pizzato FD Series, it features a rolling ball piston plunger actuator, ensuring smooth actuation with minimal friction and extended mechanical life in high-cycle applications.
Constructed with a durable metal housing, the FD2018-K21 is designed to operate reliably in harsh industrial conditions including vibration, dust, and moisture. Its slow-action contact system provides controlled switching behaviour, making it suitable for applications requiring stable and sequential signal transitions.
This variant includes a PG13.5 threaded conduit entry with assembled cable gland (6–12 mm), simplifying installation and ensuring secure cable termination. With a 1 NO + 2 NC contact configuration, positive opening operation, and IP67 protection rating, it is ideal for both standard automation and safety-related machinery.
