Why Choose the Pizzato HPAA050F-2PNH90 Safety Hinge Switch?
The Pizzato HPAA050F-2PNH90 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.
Constructed with a durable metal housing, this switch is built for long-term performance in demanding industrial environments. Its integrated hinge design eliminates the need for separate actuators, improving installation efficiency while ensuring consistent alignment throughout its lifecycle.
This model features a 1NO + 2NC contact configuration with positive opening operation and a snap-action switching mechanism. It includes a 2 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 angles.
Key Advantages
- Integrated safety hinge switch for guard monitoring.
- 1NO + 2NC contacts for safety redundancy and signalling.
- 90° activation angle for delayed switching operation.
- 2 m cable for flexible installation.
- Durable metal housing for harsh industrial environments.
- Eliminates actuator alignment issues found in conventional safety switches.

Reliable Guard Monitoring with Wide-Angle Activation
The HPAA050F-2PNH90 is designed for applications where switching should occur at a wider guard opening angle. The 90° activation angle ensures the safety circuit is triggered only after the guard has opened significantly, providing controlled sequencing and improved operational flexibility.
Its 1NO + 2NC configuration enables integration into dual-channel safety systems while also providing auxiliary signalling. The positive opening contacts ensure reliable disconnection of the safety circuit, delivering high safety integrity even in demanding industrial environments.
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 both safety redundancy and status monitoring.
