FR 552-R6 Pizzato Position switch with roller lever
Pizzato FR 552-R6 industrial position switch with a straight rotating roller lever, 1NO+1NC snap-action contacts, positive opening, PG 13.5 cable entry and IP67/IP69K protection for reliable machinery position detection.
Why Choose the Pizzato FR 552-R6 Position Switch?
The Pizzato FR 552-R6 is a robust industrial position switch with a straight rotating roller lever, designed for reliable mechanical position and movement detection in machinery and automation systems. As part of the established Pizzato FR position switch series, it combines a durable technopolymer housing with a roller lever actuator for dependable electromechanical switching in demanding industrial applications.
The roller lever provides smooth mechanical operation when contacted by moving machine components, making the FR 552-R6 particularly suitable for repeated position sensing. Its rotating lever mechanism converts physical movement into a reliable electrical switching signal, while the roller contact helps reduce sliding friction between the actuator and the moving component.
The FR 552-R6 incorporates 1NO+1NC snap-action contacts, a single PG 13.5 threaded cable entry and positive-opening operation. With IP67 protection according to EN 60529 and IP69K protection according to ISO 20653, it is well suited to conveyors, production equipment, material handling systems and other industrial machinery requiring dependable position feedback.

Reliable Position Detection for Industrial Machinery
Position switches such as the Pizzato FR 552-R6 provide an electromechanical switching signal when a moving machine component operates the roller lever. This enables industrial control systems to detect predefined positions, monitor travel limits and initiate control functions at specific points during a machine operating cycle.
The straight roller lever configuration is particularly effective where a moving component repeatedly passes across the actuator. Its rolling contact supports smooth mechanical operation, while the 1NO+1NC snap-action contact block and positive-opening mechanism provide reliable electrical switching for PLC inputs, relays, contactors and other industrial control equipment.
Typical Applications
- Industrial machinery position detection.
- Conveyor and material handling systems.
- Packaging and production machinery.
- End-of-travel and movement monitoring.
- Automated manufacturing equipment.
- Mechanical handling and processing machinery.
- OEM automation systems and machine building.
