Why Choose the Pizzato HP AA050F-2PNH30 Safety Hinge Switch?
The Pizzato HP AA050F-2PNH30 is an industrial HP series safety hinge switch designed for monitoring hinged guards, access doors and protective panels on machinery. The electrical safety switch is integrated directly into the mechanical hinge, providing guard position monitoring without requiring a conventional separate actuator and switch body.
This model incorporates the 50F snap-action contact block with 1NO + 2NC contacts and positive opening of the safety contacts. The H30 configuration provides a 30° activation angle, allowing the switching point to be matched to applications where the safety circuit must respond after a defined amount of guard rotation.
The HP AA050F-2PNH30 has a robust metal body with a 100 × 50 mm movable part, a right-hand movable section and rear cable outlet. Electrical connection is provided by an integrated 2 m black PVC cable. With IP67 protection according to EN 60529 and IP69K according to ISO 20653, the hinge switch is well suited to demanding industrial machine guarding applications.

Integrated Safety Monitoring with a Defined Activation Angle
Safety hinge switches detect the opening of a movable machine guard through the rotational movement of the hinge itself. When the guard reaches the configured switching angle, the internal safety contacts change state so that a correctly designed safety control system can stop hazardous machine functions or prevent them from starting.
The HP AA050F-2PNH30 combines this integrated hinge monitoring principle with a defined 30° activation angle. Its snap-action 1NO + 2NC contact arrangement provides clear switching as the guard moves through the activation point, while the concealed hinge-based design eliminates the separate actuator alignment required by conventional tongue-operated safety switches.
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.
- Machine enclosures requiring a defined guard activation angle.
