Why Choose the Pizzato HP AB052C-0.25SN Safety Hinge Switch?
The Pizzato HP AB052C-0.25SN is a compact and robust safety hinge switch designed for monitoring hinged machine guards, access doors and protective panels. As part of the Pizzato HP Series, it combines the mechanical hinge and electrical safety-switching functions in a single assembly for efficient machine-guard integration.
The 52C contact block provides a 1NO + 1NC slow-action contact configuration, with positive opening operation of the normally closed safety contact. This arrangement enables dependable guard-position monitoring while also providing a normally open contact for auxiliary signalling or control purposes.
The HP AB052C-0.25SN uses a durable powder-coated metal housing and an integrated 0.25 m cable. Its HP Series construction provides IP67 / IP69K protection, making the switch suitable for demanding industrial machinery where compact hinge-mounted guard monitoring is required.
Key Advantages
- Combines the hinge and safety-switching functions in one compact device.
- 1NO + 1NC slow-action contacts support safety monitoring and auxiliary signalling.
- Positive opening NC contact supports reliable safety-circuit interruption.

Integrated Safety Monitoring at the Guard Hinge
Safety hinge switches detect the position of a movable machine guard directly at its pivot point. Opening or closing the hinged guard operates the internal electrical contacts, allowing the machine safety system to determine the guard position without requiring a conventional tongue or separate actuator.
The Pizzato HP AB052C-0.25SN combines this integrated hinge arrangement with slow-action switching and positive opening of the NC contact. This makes it a practical solution for machine builders seeking compact, mechanically integrated guard monitoring with robust environmental protection.

- Industrial machine guard doors.
- Hinged safety panels and protective covers.
- Packaging and production machinery.
- Automated assembly equipment.
- Machine tools and processing systems.
- Conveyor and material handling equipment.
- OEM machinery and industrial automation systems.
