FZ 1451-M2 Pizzato Position switch with roller lever
Pizzato FZ 1451-M2 position (limit) switch with a roller lever, IP67 glass-fibre technopolymer housing and 1 NO + 1 NC snap-action positive-opening contacts for industrial machine position sensing.
Why Choose the Pizzato FZ 1451-M2 Position Switch?
The Pizzato FZ 1451-M2 is a robust position (limit) switch from the Pizzato FZ series for standard applications, fitted with a roller lever. It is designed for reliable position and end-of-travel detection of moving machine parts in industrial automation and machine-building applications.
Built into a glass-fibre reinforced technopolymer housing with an IP67 protection degree, the FZ 1451-M2 withstands dust, washdown and demanding factory environments. Its positive-opening NC contact (in conformity with EN / IEC 60947-5-1) makes it suitable for use in machine safety circuits.
With 1 NO + 1 NC snap-action contacts, a 10 A thermal current and a rated insulation voltage of 500 V AC, the switch integrates directly into standard control and signalling circuits.

- Positive opening to EN / IEC 60947-5-1.
Reliable Position Sensing for Industrial Machinery
Position switches such as the Pizzato FZ series detect the presence, position or end-of-travel of moving machine components and relay that state to the control system. The roller lever transmits motion from a passing cam or moving part to actuate the switch, with the lever position adjustable to suit the machine geometry.
The glass-fibre reinforced technopolymer construction, positive-opening contacts and IP67 sealing make the FZ 1451-M2 dependable in conveyors, handling systems and automated machinery where accurate, long-life switching is essential.
Typical Applications
- Conveyors and material-handling systems.
- End-of-travel detection on moving machine parts.
- Automated production and assembly machinery.
- Packaging and processing equipment.
- Machine guarding and safety circuits.
- General industrial automation.
