The Pizzato FX502-A is a compact and reliable industrial position switch with one-way roller actuator, engineered for precise directional position detection in automation systems. As part of the proven Pizzato FX series, it offers dependable switching performance and long service life in demanding industrial environments.
This model features a one-way roller lever actuator, ensuring actuation occurs only in a single direction. This makes it ideal for conveyor systems and machinery where reverse movement must not trigger switching. Its robust technopolymer housing delivers excellent resistance to dust, moisture and mechanical stress.
The FX502-A is equipped with 1 normally open (NO) and 1 normally closed (NC) snap-action contact with positive opening functionality, making it suitable for both control and safety circuits. It is designed without a reset mechanism for continuous industrial operation and includes dual conduit entries for flexible installation.

Directional Position Detection for Industrial Systems
Position switches such as the Pizzato FX502-A are used to detect movement or position of machine components within industrial machinery. The one-way roller actuator ensures activation only in a defined direction, improving control accuracy and preventing unwanted switching caused by reverse movement.
The snap-action contacts with positive opening provide reliable switching and safe circuit interruption, making the FX502-A suitable for both general automation and safety-related applications.
Typical Applications
Conveyor systems with directional detection.
Industrial automation and production lines.
Material handling and packaging machinery.
Mechanical position monitoring systems.
OEM machinery and control panel integration.
Safety circuits requiring NO and NC outputs.
