Why Choose the Pizzato HPAA052D-3AN Safety Hinge Switch?
The Pizzato HPAA052D-3AN is a robust safety hinge switch engineered for monitoring hinged guards and access doors in industrial machinery. As part of the proven Pizzato HP Series, it integrates the switching mechanism directly into the hinge, eliminating the need for external actuators and delivering a compact, tamper-resistant safety solution.
Constructed with a durable metal housing, this hinge switch is designed for long-term reliability in demanding industrial environments. It ensures machinery only operates when guards are securely closed, helping maintain compliance with machinery safety standards and protecting operators.
This model features 2 NC slow-action contacts, a 3 metre oil-resistant PVC cable, and a 0° activation angle, providing immediate switching response and dependable protection for safety-critical applications.

Fail-Safe Safety Monitoring with NC Contacts
The HPAA052D-3AN is designed with a dual NC contact configuration, making it ideal for fail-safe safety circuits. In the event of a wiring fault or disconnection, the circuit opens, ensuring the machine stops safely.
Its 0° activation angle ensures the safety system reacts instantly when the guard begins to open, while the integrated hinge design removes alignment issues and reduces tampering risks associated with conventional safety switches.
Typical Applications
- Safety monitoring of hinged machine guards and access doors.
- Industrial automation and production machinery.
- Packaging and processing equipment.
- Material handling and conveyor systems.
- Machine tools and industrial enclosures.
- OEM machinery installations requiring fail-safe safety circuits.
