Why Choose the Pizzato HPAA050M-2PNH90 Safety Hinge Switch?
The Pizzato HPAA050M-2PNH90 is a heavy-duty safety hinge switch designed for reliable 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 robust metal housing, this switch is engineered for long-term performance in harsh industrial environments. Its integrated hinge construction eliminates the need for external actuators, reducing installation complexity while ensuring consistent alignment and dependable operation.
This model features a 2NO + 2NC contact configuration with positive opening operation and a snap-action switching mechanism. It is supplied with a 2 metre oil-resistant PVC cable 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-2PNH90 is designed for advanced safety systems requiring multiple outputs. Its 2NO + 2NC configuration enables flexible integration into complex control systems, supporting both safety circuits and machine status signalling.
The 90° activation angle ensures the safety circuit is triggered only after the guard has opened significantly, allowing controlled sequencing of machine operations. The positive opening contacts guarantee reliable disconnection of the safety circuit, ensuring high safety integrity even under demanding 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.
- Complex safety circuits requiring multiple contact outputs.
