Why Choose the Pizzato HP AB050F-8SN Safety Hinge Switch?
The Pizzato HP AB050F-8SN is an industrial HP series safety hinge switch designed for monitoring hinged guards, access doors and protective panels on machinery. By integrating the electrical safety switching function directly into the hinge assembly, it provides reliable guard position detection without requiring a conventional separate actuator and externally mounted safety switch.
This model incorporates the 50F contact block with 1NO + 2NC snap-action contacts and positive-opening safety operation. The three-contact arrangement provides dedicated switching for integration into an appropriately designed machine safety circuit, while snap-action operation provides decisive contact switching as the guard moves through the operating point.
The HP AB050F-8SN features a robust metal body with a 100 × 75 mm movable part and a bottom cable outlet. Electrical connection is provided by an integrated 8 m PVC cable with 7 × 0.5 mm² conductors. With IP67 protection according to EN 60529 and IP69K protection according to ISO 20653, the HP series is well suited to demanding industrial machine guarding applications.

Integrated Safety Monitoring for Hinged Machine Guards
Safety hinge switches monitor the position of a movable machine guard through the rotational movement of the hinge itself. As the guard opens and the hinge rotates through its switching point, the internal safety 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 directly into the hinge eliminates the alignment requirements associated with conventional tongue-operated safety switches and separate actuators. The HP AB050F-8SN combines this compact installation principle with a three-contact snap-action block and an extended 8 m cable, making it particularly practical for larger machine enclosures or applications where the connection point is located some distance from the guard.
Typical Applications
- Hinged industrial machine guards.
- Safety doors and protective access panels.
- Automated production and assembly machinery.
- Packaging and processing equipment.
- Robotic cells and automated manufacturing systems.
- Large machine enclosures requiring an extended safety switch cable.
