FR 938-A Pizzato Position switch for rotating levers

Why Choose the Pizzato FR938-A Position Switch?

The Pizzato FR938-A is a safety-oriented industrial position switch with reset function, designed for precise detection of mechanical movement in automation systems and machinery. As part of the dependable Pizzato FR series, it delivers consistent switching performance and enhanced operational safety in demanding industrial environments.

Built with a durable technopolymer housing, the FR938-A offers excellent resistance to dust, moisture and mechanical stress. Its slow-action switching mechanism ensures stable and controlled electrical switching, making it ideal for applications where reliability and safety are critical.

This variant features a 2NC contact configuration with positive opening operation and includes an integrated manual reset function. This ensures the switch must be intentionally reset after activation, making it particularly suitable for safety interlock systems. It is supplied without actuator, allowing flexible integration with compatible rotating lever actuators.
