FZ 2120-M2 Pizzato Position switch, coil spring with plastic point

Why Choose the Pizzato FZ2120-M2 Position Switch?

The Pizzato FZ2120-M2 is a robust industrial position and limit switch with a coil spring actuator and plastic tip, designed for dependable position, presence and movement detection in machinery and automation systems. As part of the established Pizzato FZ series, it combines a durable metal enclosure with a flexible spring actuator that accommodates multidirectional contact with moving machine components.

The FZ2120-M2 incorporates a 3NC slow-action contact configuration using Pizzato's contact block 21. All three contacts are normally closed, providing three switching channels for machine monitoring, interlocking and control. The slow-action mechanism provides defined contact operation according to actuator movement, while the normally closed contacts incorporate positive-opening operation for appropriate safety-related applications.

The coil spring with plastic point is particularly useful where the direction or alignment of a moving component can vary, allowing the actuator to deflect when contacted rather than requiring precise linear engagement. The M2 configuration provides M20 × 1.5 threaded cable entries, while the external gasket and robust FZ-series construction help provide dependable operation in demanding industrial machinery installations.

Reliable Position Detection for Industrial Machinery

Position switches such as the Pizzato FZ2120-M2 provide an electromechanical method of detecting moving machine components. When a component contacts the plastic-tipped coil spring, the flexible actuator deflects and transfers movement to the internal switching mechanism, changing the state of the three normally closed contacts and providing electrical signals to the associated machine control, monitoring or interlocking system.

The flexible spring actuator makes the FZ2120-M2 particularly useful where the actuating component may approach from different directions or where a rigid plunger would require more precise alignment. Combined with its 3NC slow-action contact arrangement, positive-opening operation, external actuator gasket and metric cable-entry configuration, the switch provides dependable mechanical detection for industrial automation and machinery applications.

Typical Applications

• Industrial machinery position and presence detection.
• Conveyor and material handling systems.
• Packaging and production machinery.
• Moving-component and overtravel detection.
• Machine monitoring and interlocking systems.
• Automated manufacturing and assembly equipment.
