Why Choose the Pizzato HPAA050F-3PN Safety Hinge Switch?
The Pizzato HPAA050F-3PN is a high-reliability safety hinge switch designed for monitoring hinged safety guards in industrial machinery. As part of the robust Pizzato HP series, it integrates the safety switching mechanism directly into the hinge, ensuring immediate machine shutdown when a guard is opened.
Constructed with a durable metal housing, this switch is engineered for long-term operation in demanding industrial environments. Its integrated hinge design removes the need for external actuators, reducing installation complexity and ensuring consistent alignment over time.
This model features a 1NO + 2NC contact configuration with positive opening operation and a snap-action switching mechanism. It is supplied with a 3 metre oil-resistant PVC cable with rear output, making it suitable for a wide range of industrial safety applications.

Reliable Guard Monitoring with Flexible Contact Output
The HPAA050F-3PN is designed for applications requiring both safety and signalling outputs. Its 1NO + 2NC configuration allows integration into dual-channel safety circuits while also providing auxiliary feedback for control systems.
By integrating the switch directly into the hinge, the device ensures consistent operation even in high-vibration or high-cycle environments. The positive opening contacts guarantee reliable disconnection of the safety circuit when the guard is opened, ensuring high safety integrity.
Typical Applications
- Hinged safety doors on industrial machinery.
- Automation systems and production lines.
- Packaging and processing equipment.
- Robotic safety enclosures.
- Machine tools and manufacturing systems.
- Applications requiring safety redundancy and status monitoring.
