Why Choose the Pizzato HP AA052C-KAMH90 Safety Hinge Switch?
The Pizzato HP AA052C-KAMH90 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 hinge and electromechanical safety switching functions into a compact assembly, reducing the need for a separate external safety switch and actuator.
The HP AA052C-KAMH90 incorporates a 1NO + 1NC slow-action contact configuration with positive opening of the safety contact. Its 90° activation angle provides a defined switching position during guard rotation, while the integrated 5-pole M12 connector provides a convenient detachable electrical connection.
Designed around a durable metal body, this variant features a 100 × 45 mm movable part and connector output from the bottom. Protection ratings of IP67 according to EN 60529 and IP69K according to ISO 20653 support installation in demanding industrial machine guarding environments.

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 defined switching position, the internal contacts change state so that an appropriately designed machine safety circuit can detect guard movement and initiate the required safe response.
The Pizzato HP Series integrates the safety switching mechanism directly into the hinge assembly, helping reduce exposed components and eliminating the need for a separate actuator in suitable applications. The HP AA052C-KAMH90 combines slow-action switching, positive-opening safety operation, a 90° activation angle and an M12 connection for dependable integration into industrial machine guarding systems.
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 interlock systems.
