Why Choose the Pizzato HPAA052C-1SN Safety Hinge Switch?
The Pizzato HPAA052C-1SN is a reliable safety hinge switch designed for monitoring hinged safety guards on industrial machinery. As part of the robust Pizzato HP series, it integrates the switching mechanism directly into the hinge, ensuring accurate guard position detection with a compact and durable design.
This integrated 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 provide dependable disconnection even in fault conditions, making it suitable for safety-critical applications.
The HPAA052C-1SN features a 1 normally open (NO) and 1 normally closed (NC) contact configuration with a slow-action switching mechanism. It is supplied with a 1 metre oil-resistant PVC cable and operates with a 0° activation angle, ensuring consistent and precise guard monitoring.

Reliable Guard Monitoring for Industrial Safety
Safety hinge switches such as the HPAA052C-1SN 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. The HP series is classified as mechanical interlocking devices in accordance with EN ISO 14119, widely used across industrial machinery safety systems.
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.
