HP AA052C-1PNH75 Pizzato Safety hinge switch

Why Choose the Pizzato HPAA052C-1PNH75 Safety Hinge Switch?

The Pizzato HPAA052C-1PNH75 is a robust and precision-engineered safety hinge switch designed for monitoring hinged safety guards in industrial machinery. As part of the proven 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 reliability in demanding industrial environments. Its integrated hinge design eliminates the need for external actuators, reducing installation complexity while ensuring consistent alignment and dependable performance.

This model features a 1NO + 1NC contact configuration with positive opening operation and a slow-action switching mechanism. It is supplied with a 1 metre oil-resistant PVC cable and a defined 75° activation angle, making it ideal for applications requiring delayed switching at wider guard opening positions.

Reliable Guard Monitoring with Delayed Switching Control

The HPAA052C-1PNH75 is designed for applications where switching should occur at a later stage of guard movement. The 75° activation angle ensures the safety circuit is triggered only after the guard has opened significantly, improving operational control and process sequencing.

Its 1NO + 1NC configuration enables integration into safety circuits while also providing auxiliary signalling. The positive opening contacts ensure reliable mechanical disconnection, delivering dependable safety performance even under demanding industrial 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.
• Applications requiring controlled switching positions.
