Why Choose the Pizzato FM501-W3M2 Limit Switch?

The Pizzato FM501-W3M2 is a robust limit/position switch with integrated reset mechanism, designed for precise position detection and enhanced safety in industrial automation systems. As part of the proven Pizzato FM series, it offers reliable operation in demanding environments where controlled restart is essential.

This model features a short piston plunger actuator combined with a W3 simultaneous reset device, ensuring the switch must be reset before normal machine operation resumes. Its metal housing construction provides excellent durability and resistance to mechanical stress in industrial applications.

The FM501-W3M2 is equipped with a 1 normally open (NO) and 1 normally closed (NC) snap-action contact configuration with positive opening operation, making it suitable for both control and safety circuits. The M20 x 1.5 conduit entry enables straightforward installation in industrial wiring environments.

  • Reliable position detection with integrated reset function.
  • Short plunger actuator for precise and repeatable actuation.
  • 1 NO + 1 NC contacts for flexible control and signalling.
  • Positive opening contacts for enhanced safety compliance.
  • W3 simultaneous reset mechanism prevents unintended restart.
  • IP67 / IP69K protection for harsh industrial and washdown environments.

Key Features

  • Pizzato FM series limit switch.
  • Short piston plunger actuator.
  • Integrated W3 reset device for controlled reset.
  • 1 NO + 1 NC snap-action contact block (B5).

Controlled Reset for Safe Industrial Operation

Limit switches with reset functionality, such as the FM501-W3M2, are essential in applications where machinery must not automatically restart after actuation. The integrated reset mechanism ensures operators must intentionally reset the system, reducing risk and improving operational safety.

The Pizzato FM series is widely used by automation engineers and OEM machine builders due to its rugged construction, precise actuation and compatibility with industrial control systems.

Typical Applications

  • Industrial machinery requiring controlled restart.
  • Safety interlocking systems.
  • Conveyor and material handling equipment.
