Why Choose the Pizzato HPAA050F-2PNH45 Safety Hinge Switch?
The Pizzato HPAA050F-2PNH45 is a high-performance safety hinge switch designed for precise monitoring of 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 durable metal housing, this switch is engineered for reliable operation in harsh industrial environments. Its integrated hinge construction eliminates the need for external actuators, reducing installation complexity and ensuring long-term alignment accuracy.
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 45° activation angle, making it ideal for applications requiring delayed or controlled switching points during guard movement.

Reliable Guard Monitoring with Delayed Switching Control
The HPAA050F-2PNH45 is specifically designed for applications where a delayed switching point is required. The 45° activation angle ensures the safety circuit is triggered only after the guard has moved beyond a defined position, improving operational control and process safety.
Its 1NO + 2NC contact configuration supports dual-channel safety circuits alongside auxiliary signalling outputs. The positive opening contacts ensure reliable disconnection of the safety circuit, even under demanding mechanical conditions, providing high safety integrity.
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.
