Why Choose the Pizzato FR1651-K21 Position Switch?
The Pizzato FR1651-K21 is a high-reliability industrial position switch with roller lever, designed for precise mechanical position detection in automation and safety-critical systems. As part of the proven Pizzato FR series, it delivers consistent switching performance in demanding industrial environments.
This model features a roller lever actuator with central technopolymer roller (20 mm), ensuring smooth actuation and reduced mechanical wear during continuous operation. The robust technopolymer housing offers excellent resistance to impact, dust and moisture, making it suitable for long-term use in harsh industrial conditions.
Equipped with 2 normally closed (NC) slow-action contacts and positive opening functionality, the FR1651-K21 provides stable and safe switching for control and safety circuits. The K21 version includes a pre-assembled cable gland for cables typically between 6–12 mm, simplifying installation and ensuring secure wiring connections.

Reliable Position Detection for Industrial Systems
Position switches such as the Pizzato FR1651-K21 are used to monitor machine movement and provide feedback signals to control systems. When actuated, the roller lever engages the internal mechanism, triggering contact changes that enable precise machine control and safe operation.
The slow-action mechanism ensures stable switching behaviour, while the positive opening contacts provide additional safety assurance. This makes the FR1651-K21 ideal for applications requiring both reliability and compliance with safety standards.
Typical Applications
- Machine position monitoring and end-of-travel detection.
- Safety circuits in industrial machinery.
- Conveyor and material handling systems.
- Packaging and production machinery.
- Industrial automation and control panels.
- OEM machine building applications.
