FM 938-W3 Pizzato Position switch for rotating levers with reset device

Why Choose the Pizzato FM938-W3 Position Switch?

The Pizzato FM938-W3 is a heavy-duty industrial position switch with integrated reset device, designed for precise detection of mechanical movement in automation and safety systems. As part of the proven Pizzato FM series, it delivers reliable switching performance and long service life in demanding industrial environments.

Constructed with a robust metal housing and a standard PG13.5 threaded conduit entry, the FM938-W3 is engineered for straightforward installation in machinery and control panels. The integrated W3 reset device ensures synchronised actuation between the actuator movement and the contact block, improving reliability in applications subject to vibration or dynamic loads.

This model features a 2NC slow action contact configuration with positive opening operation, making it particularly suitable for safety circuits where reliable disconnection is essential. With an IP67 protection rating, it performs reliably in harsh environments exposed to dust, moisture and mechanical stress.
