Why Choose the Pizzato FD 541-K50 Position Switch?
The Pizzato FD 541-K50 is a heavy-duty position switch with bi-stable operation, engineered for reliable mechanical detection and maintained switching in industrial automation systems. As part of the robust Pizzato FD series, it delivers consistent performance and long service life in demanding industrial environments.
This K50 variant features a metal housing with PG 13.5 threaded conduit entry and a factory-fitted M12 5-pole metal connector, enabling fast, secure and standardised electrical connection. It incorporates a 1NO + 1NC snap action contact block with bistable switching, allowing the switch to remain in its last actuated position until reset.
With an IP67 protection rating and positive opening, the FD 541-K50 is designed for reliable operation in environments exposed to dust, moisture and vibration, making it suitable for both control and safety-related applications.
Key Advantages
- Bistable operation for maintained switching states.
- 1NO + 1NC contact configuration for flexible control circuits.
- Snap action switching for fast and precise response.
- M12 connector (K50) for quick and reliable plug-in wiring.
- Positive opening ensures safe disconnection in safety circuits.
- IP67 protection rating for resistance to dust and water ingress.
Key Features
- Pizzato FD series heavy application position switch.
- FD 541-K50 with bi-stable single-track lever actuator.
- Metal housing with industrial-grade construction.
- PG 13.5 entry with integrated M12 5-pole connector.
- 1 normally open + 1 normally closed contact.
- Snap action switching mechanism (B5).
- Silver contact material.
- Two stable positions (bistable switching).
- IP67 protection rating according to EN 60529.
Bistable Switching for Controlled Machine States
The FD 541-K50 maintains its switching position after actuation, making it ideal for applications where a machine state must be retained without continuous input. This bistable function simplifies control logic and improves operational stability in automated systems.
The addition of an M12 connector enables fast installation and easy replacement, reducing downtime in industrial environments while maintaining secure electrical connections.
Typical Applications
- Machine control systems requiring maintained switching states.
- Industrial automation and control panels.
- Position monitoring of machinery and tooling.
- Conveyor and material handling systems.
- Packaging and production machinery.
- Safety and interlocking applications.
