Why Choose the Pizzato HP AA052C-2QNH15 Safety Hinge Switch?
The Pizzato HP AA052C-2QNH15 is a robust safety hinge switch designed for monitoring hinged machine guards, doors and access panels. Part of the Pizzato HP Series, it integrates the electromechanical safety switching function directly into the hinge body, providing a compact guard-monitoring solution without requiring a separate external actuator.
The HP AA052C-2QNH15 incorporates a 1NO + 1NC slow-action contact block with positive opening of the safety contact. The H15 configuration provides a 15° activation angle, allowing the switching point to be configured for applications where safety monitoring is required after a defined amount of guard rotation.
This variant is supplied with a 2 m PVC cable and uses the QN configuration with the cable exiting from the rear. Its durable metal construction, 100 × 45 mm movable part and IP67 / IP69K protection make it suitable for demanding industrial machine guarding applications.

Reliable Guard Monitoring for Hinged Machinery
Safety hinge switches monitor the position of hinged machine guards through rotational movement of the hinge itself. As the guard reaches the configured switching angle, the internal contacts change state so that an appropriately designed machine safety circuit can detect the movement and initiate the required safe response.
The Pizzato HP Series integrates this switching mechanism directly into the hinge body, helping reduce exposed components and eliminating the need for a separate actuator in suitable applications. The HP AA052C-2QNH15 combines slow-action switching, positive-opening safety operation, a 15° activation angle, robust metal construction and a pre-wired connection for dependable industrial guard monitoring.
Typical Applications
- Industrial machine guard doors.
- Hinged safety guards and access panels.
- Packaging and production machinery.
- Automated manufacturing equipment.
- Conveyor guarding systems.
- Machine tools and processing equipment.
- OEM machinery and industrial safety systems.
