Why Choose the Pizzato HPAA050F-3PNH90 Safety Hinge Switch?
The Pizzato HPAA050F-3PNH90 is a precision-engineered safety hinge switch designed for monitoring hinged safety guards in industrial machinery. As part of the advanced Pizzato HP series, it integrates the switching mechanism directly into the hinge, ensuring immediate machine shutdown when a guard is opened.
Built with a rugged metal housing, this switch is designed for reliable long-term operation in demanding industrial environments. Its integrated hinge construction removes the need for external actuators, reducing installation complexity while maintaining consistent alignment throughout its service life.
This model features a 1NO + 2NC contact configuration with positive opening operation and a snap-action mechanism. It is supplied with a 3 metre oil-resistant PVC cable with rear output and a defined 90° activation angle, making it ideal for applications requiring delayed switching at wider guard opening positions.

Reliable Guard Monitoring with Wide-Angle Activation
The HPAA050F-3PNH90 is designed for applications where switching must occur at a wider guard opening angle. The 90° activation angle ensures that the safety circuit is triggered only after the guard has opened significantly, allowing improved process control and operational sequencing.
Its 1NO + 2NC configuration supports dual-channel safety systems alongside auxiliary signalling. The positive opening contacts ensure reliable disconnection of the safety circuit, delivering high safety integrity even under demanding industrial conditions.
Typical Applications
- Hinged safety guards requiring delayed switching activation.
- Industrial automation and production machinery.
- Packaging and processing equipment.
- Robotic safety enclosures and access doors.
- Machine tools and manufacturing systems.
- Applications requiring safety redundancy and status monitoring.
