FR 934-W3M2 Pizzato Position switch with reset

Why Choose the Pizzato FR 934-W3M2 Position Switch?

The Pizzato FR 934-W3M2 is a robust industrial position switch with coiled spring lever and reset device designed for reliable position detection, machine monitoring and control applications. As part of the proven Pizzato FR series, it combines a reinforced technopolymer housing with a flexible spring actuator, slow-action contacts and high environmental protection for dependable operation in demanding industrial environments.

This position switch incorporates a coiled spring lever with plastic tip, allowing multidirectional mechanical actuation where precise alignment between the moving machine component and switch is impractical. The integrated W3 reset device is positioned between the switch body and operating head and can be rotated independently, providing flexible installation and controlled reset functionality.

The FR 934-W3M2 features a 2NC slow-action contact configuration and an M20 × 1.5 cable entry. The FR series provides robust electrical performance and an IP67 protected enclosure, making this switch well suited to industrial machinery, conveyors and automated equipment requiring reliable mechanical position sensing.

Reliable Position Detection for Industrial Machinery

Industrial position switches such as the Pizzato FR 934-W3M2 detect the presence, position or movement of mechanical components and provide an electrical switching signal to the machine control system. Its flexible coiled spring actuator can be deflected by moving equipment from different directions, making it particularly useful where the actuating component does not follow a precisely controlled path.

The W3 reset mechanism synchronises operation of the actuator and contact block and can be independently rotated relative to the operating head for installation flexibility. Combined with the FR series reinforced enclosure and slow-action 2NC contacts, this provides a versatile solution for dependable mechanical position detection in industrial automation systems.

Typical Applications

• Industrial machinery position detection.
• Conveyors and material handling systems.
• Packaging and production machinery.
• Machine tools and automated equipment.
• Applications requiring multidirectional or flexible actuation.
• Mechanical travel and end-position monitoring.
