Why Choose the Pizzato HP AB052C-5SE Safety Hinge Switch?
The Pizzato HP AB052C-5SE is an industrial HP series safety hinge switch designed for monitoring hinged guards, doors and protective panels on machinery. By integrating the safety switching function directly into the hinge assembly, it provides reliable guard position monitoring without requiring a conventional separate actuator and switch body.
The 52C contact block provides 1NO + 1NC slow-action contacts, with positive opening of the safety contact. This arrangement allows the movement of the guard to operate the electrical contacts directly through the hinge mechanism, providing a compact solution for safety-related machine control systems.
The HP AB052C-5SE uses a robust metal body with a 100 × 75 mm movable hinge section. The HP series provides IP67 protection according to EN 60529 and IP69K protection according to ISO 20653, making it suitable for demanding industrial environments. Pizzato specifies that its HP safety hinge switches must be combined exclusively with compatible Pizzato HP or HC series hinges to ensure correct operation of the safety device.

Integrated Safety Monitoring for Hinged Machine Guards
Safety hinge switches detect the position of a movable guard through the rotational movement of the hinge itself. When the guard moves away from its safe position, the internal contacts change state so that a correctly designed safety control system can stop hazardous machine functions or prevent them from starting.
Integrating the switching mechanism into the hinge eliminates the need to align a separate tongue actuator with an externally mounted safety switch. This can simplify machine construction, reduce exposed safety components and provide a discreet installation. The HP AB052C-5SE should be installed with compatible Pizzato HP or HC hinges in accordance with the manufacturer's requirements to maintain correct mechanical operation of the safety system.

- Hinged industrial machine guards.
- Safety doors and protective access panels.
