Why Choose the Pizzato HP AA052C-7ANH90 Safety Hinge Switch?
The Pizzato HP AA052C-7ANH90 is a robust HP series safety hinge switch designed for monitoring hinged guards, doors and protective covers on industrial machinery. By integrating the safety switching function directly into the hinge assembly, the HP series provides compact and tamper-resistant guard position monitoring without requiring a conventional separate actuator.
The HP AA052C-7ANH90 uses the 52C slow-action contact block with 1NO + 1NC contacts and incorporates positive opening of the safety contact. This enables reliable detection of guard movement for connection to an appropriate machine safety circuit, while the integrated hinge arrangement helps provide a clean installation with fewer externally accessible safety components.
Designed for demanding industrial environments, the HP series features a durable metal housing and provides IP67 protection according to EN 60529 and IP69K protection according to ISO 20653. The 100 × 45 mm movable hinge section provides a substantial mounting interface for machine guarding, while the concealed switching mechanism helps reduce opportunities for tampering.

Integrated Safety Monitoring for Hinged Machine Guards
Safety hinge switches monitor the position of hinged guards by integrating the switching mechanism directly into the hinge assembly. When the guard is moved away from its permitted operating position, the switch contacts change state so that a correctly designed safety control system can initiate the required machine stop or inhibit hazardous operation.
The Pizzato HP series is designed to provide effective guard monitoring while minimising externally visible safety components. The integrated construction makes the safety device less susceptible to accidental damage or straightforward manipulation and is particularly useful where space around a machine guard is limited. For correct safety operation, HP safety hinge switches are intended to be combined with compatible Pizzato HP or HC series hinges.
Typical Applications
- Hinged industrial machine guards.
- Safety doors and protective access panels.
- Automated production and assembly machinery.
- Packaging and processing equipment.
- Robotic cells and automated manufacturing systems.
- Machine guarding requiring compact and discreet position monitoring.
