HP AA052D-2PNH90 Pizzato Safety hinge switch

Why Choose the Pizzato HPAA052D-2PNH90 Safety Hinge Switch?

The Pizzato HPAA052D-2PNH90 is a heavy-duty safety hinge switch designed for monitoring hinged safety guards in industrial machinery. As part of the robust Pizzato HP series, it integrates the switching mechanism directly into the hinge, ensuring reliable machine shutdown when a guard is opened.

Built with a durable metal housing, this switch is engineered for long-term performance in harsh industrial environments. Its integrated hinge design eliminates the need for external actuators, simplifying installation while maintaining precise alignment and consistent operation.

This model features a 2NC contact configuration with positive opening operation and a slow-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 wide guard opening positions.

Key Advantages

• Integrated safety hinge switch for guard monitoring.
• 2 normally closed contacts for dual-channel safety circuits.
• 90° activation angle for delayed switching response.
• 2 m cable for flexible installation.
• Durable metal housing for demanding industrial environments.
• Eliminates actuator alignment issues found in conventional safety switches.

Reliable Guard Monitoring with Wide-Angle Activation

The HPAA052D-2PNH90 is designed for applications where switching should occur at a later stage of guard movement. The 90° activation angle ensures the safety circuit is triggered only after the guard has opened significantly, improving process control and operational sequencing.

Its 2NC configuration provides redundancy for safety circuits, making it ideal for dual-channel safety systems. The positive opening contacts ensure reliable mechanical disconnection, delivering dependable safety performance even in demanding industrial environments.

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 dual-channel safety monitoring.
