Why Choose the Pizzato HPAA052M-2SNH45 Safety Hinge Switch?
The Pizzato HPAA052M-2SNH45 is a high-reliability safety hinge switch designed 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 demanding automation environments.
Constructed with a rugged metal housing, this device is engineered for long-term durability in harsh industrial conditions. The hinge-integrated design enhances safety integrity by preventing bypassing while simplifying installation and reducing exposed components.
Featuring a 2NO + 2NC slow-action contact configuration, 2 metre oil-resistant cable, and a 45° activation angle, the HPAA052M-2SNH45 is ideal for safety circuits requiring flexible switching geometry and reliable guard monitoring.

Integrated Safety for Hinged Guards
Safety hinge switches such as the HPAA052M-2SNH45 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 construction 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.
- Applications requiring angled hinge activation.
