Why Choose the Pizzato FR576-K21 Rope-Actuated Position Switch?
The Pizzato FR576-K21 is a compact and reliable rope-operated position switch designed for industrial signalling and control across extended machinery. As part of the trusted Pizzato FR series, it delivers dependable switching performance in conveyors, automation lines, and distributed control systems.
This version includes a factory-fitted cable gland (K21) for cable diameters typically between 6–12 mm, simplifying installation and ensuring secure wiring in industrial environments. It operates without reset, meaning the switch automatically returns to its normal state when the rope is released, enabling fast and repeatable operation.
Constructed with a robust technopolymer housing and featuring a PG13.5 conduit entry, the FR576-K21 provides IP67 and IP69K protection, making it suitable for harsh environments including dust exposure and washdown conditions.

- Contacts inverted in rest position due to actuator design.
Reliable Rope-Actuated Control for Industrial Systems
The Pizzato FR576-K21 enables accurate and repeatable signalling across extended machinery using rope actuation. When the rope is pulled, the internal mechanism activates the contacts, allowing operators or automated systems to control equipment from multiple positions along a production line.
A key design feature is that the actuator keeps the contact block activated in its rest position, meaning the normal contact states are inverted until actuation occurs. This supports specialised control logic and signalling requirements in industrial automation systems.
Typical Applications
- Conveyor and material handling systems.
- Industrial automation and control systems.
- Packaging and processing machinery.
- Position signalling across extended machine lines.
- OEM equipment and production systems.
- Distributed control applications using rope actuation.
