Why Choose the Pizzato HPAA052M-1SN Safety Hinge Switch?
The Pizzato HPAA052M-1SN is a heavy-duty safety hinge switch designed for monitoring hinged guards and access doors in industrial machinery. As part of the reliable Pizzato HP series, it integrates directly into the hinge, providing a discreet, tamper-resistant safety solution for modern automation systems.
Built with a rugged metal housing, this switch is engineered for long-term durability in demanding environments. Its hinge-integrated construction improves safety integrity by preventing bypassing while simplifying installation and reducing exposed components.
With a 2NO + 2NC slow-action contact configuration, 1 metre oil-resistant cable, and 250 V AC rating, the HPAA052M-1SN is ideal for industrial safety circuits requiring reliable guard monitoring and compact installation.

Integrated Safety for Hinged Guards
Safety hinge switches such as the HPAA052M-1SN 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.
- Compact machinery requiring short cable runs.
