Why Choose the Pizzato HPAA050M-1PNH90 Safety Hinge Switch?
The Pizzato HPAA050M-1PNH90 is a heavy-duty safety hinge switch engineered 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.
Manufactured with a rugged metal housing, this switch is designed to deliver long-term durability and consistent performance in harsh industrial environments. Its integrated hinge construction eliminates the need for external actuators, simplifying installation and maintaining reliable alignment throughout its service life.
This model features a 2NO + 2NC contact configuration with positive opening operation and a snap-action switching mechanism. It includes a 1 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 High Contact Capacity
The HPAA050M-1PNH90 is designed for advanced safety systems requiring both redundancy and multiple signalling outputs. Its 2NO + 2NC configuration allows flexible integration into complex control architectures, supporting both safety circuits and operational feedback.
The 90° activation angle ensures the safety circuit is triggered only after the guard has opened significantly, providing controlled switching behaviour and improved machine operation. Positive opening contacts guarantee reliable disconnection of the safety circuit, ensuring high safety integrity even in demanding applications.
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.
- Complex safety circuits requiring multiple contact outputs.
