Why Choose the Pizzato HPAA052C-2SNH90 Safety Hinge Switch?
The Pizzato HPAA052C-2SNH90 is a heavy-duty safety hinge switch designed for monitoring hinged safety guards on industrial machinery. As part of the proven Pizzato HP series, it integrates the switching mechanism directly into the hinge, delivering reliable guard position detection with a robust mechanical design.
This integrated safety solution ensures machinery is automatically stopped when protective guards are opened, helping to protect operators and maintain compliance with modern machine safety standards. Its positive opening contacts guarantee safe disconnection even under fault conditions, making it suitable for safety-critical applications.
The HPAA052C-2SNH90 features a 1 normally open (NO) and 1 normally closed (NC) contact configuration with a slow-action switching mechanism. It includes a 2 metre oil-resistant PVC cable and operates with a 90° activation angle, making it ideal for applications requiring wide-angle guard movement detection.

Reliable Guard Monitoring for Industrial Safety
Safety hinge switches such as the HPAA052C-2SNH90 are designed to detect whether a protective guard is open or closed. When the guard is opened, the switch interrupts the safety circuit, preventing hazardous machine movement and ensuring operator safety.
By integrating the switching mechanism directly into the hinge, this design reduces tampering risk and simplifies installation. Devices in the HP series are widely used in accordance with EN ISO 14119 for interlocking devices in industrial machinery.
Typical Applications
- Industrial machine guard monitoring.
- Access doors on automated production systems.
- Packaging and processing equipment.
- Machine tools and CNC machinery.
- Robotics and automated cells.
- OEM machinery and safety retrofits.
