Why Choose the Pizzato HPAA052M-20SN Safety Hinge Switch?
The Pizzato HPAA052M-20SN is a heavy-duty safety hinge switch engineered for monitoring hinged guards and access doors in industrial machinery. As part of the robust Pizzato HP series, it integrates directly into the hinge, delivering a discreet, tamper-resistant safety solution for modern automation systems.
Manufactured with a rugged metal housing, this switch is designed for long-term reliability in demanding industrial environments. The hinge-integrated construction enhances safety integrity by preventing bypassing while simplifying installation and reducing exposed components.
With a 2NO + 2NC slow-action contact configuration, 20 metre oil-resistant cable, and 250 V AC rating, the HPAA052M-20SN is ideal for large machinery and industrial systems requiring extended cable runs and dependable safety circuit feedback.

- Right-hand mounting orientation.
- Activation angle approx. 0°.
- Silver contacts for reliable switching performance.
Integrated Safety for Hinged Guards
Safety hinge switches such as the HPAA052M-20SN ensure that machine guards remain closed during operation. When the guard is opened, the switch interrupts the safety circuit, immediately stopping hazardous movement and protecting operators.
The hinge-integrated design significantly reduces the risk of tampering or bypassing, making it a preferred solution for high-integrity safety systems in industrial automation and machine building.
Typical Applications
- Machine guarding and access door monitoring.
- Industrial automation systems and production lines.
- Packaging, processing and assembly machinery.
- Robotic cells and automated equipment.
- OEM machine safety integration.
- Large-scale machinery requiring extended cable runs.
