FM 1801 Pizzato Position switch with plunger

Why Choose the Pizzato FM1801 Position Switch?

The Pizzato FM1801 is a robust and safety-focused position (limit) switch with plunger actuator, designed for precise detection of mechanical movement in industrial automation systems. As part of the proven Pizzato FM series, it delivers reliable performance in demanding environments where durability and operational safety are essential.

Built with a rugged metal housing and featuring a standard PG13.5 conduit entry, the FM1801 is engineered to withstand dust, moisture and mechanical stress. Its short piston plunger actuator ensures accurate and repeatable switching, making it ideal for end-of-travel detection and position monitoring in industrial machinery.

This model is equipped with a 1 NO + 1 NC slow-action contact configuration with positive opening contacts, ensuring reliable disconnection in safety circuits. Designed without automatic reset, it is well suited for controlled industrial processes and safety-related control systems.

Reliable Safety and Position Detection

Position switches such as the Pizzato FM1801 are widely used in industrial automation systems to detect the movement or position of machine components. The plunger actuator responds to linear motion, ensuring accurate and repeatable switching in both control and safety applications.

Thanks to its positive opening contacts, the FM1801 is particularly suited for safety circuits where guaranteed disconnection is required, even in the event of contact welding, improving overall machine safety and compliance.

Typical Applications

• Machine safety circuits and interlock systems.
• End-of-travel detection in industrial machinery.
• Conveyor and material handling systems.
• Packaging and processing equipment.
• Automated production lines.
• OEM automation and control systems.
