Why Choose the Pizzato HPAA052C-3SN Safety Hinge Switch?
The Pizzato HPAA052C-3SN is a robust safety hinge switch engineered for monitoring hinged safety guards on industrial machinery. As part of the dependable Pizzato HP series, it integrates the switching mechanism directly into the hinge, ensuring accurate guard position detection with a durable and compact 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 provide reliable disconnection even under fault conditions, making it suitable for safety-critical applications.
The HPAA052C-3SN features a 1 normally open (NO) and 1 normally closed (NC) contact configuration with a slow-action switching mechanism. It is supplied with a 3 metre oil-resistant PVC cable and operates with a 0° activation angle, delivering precise and consistent guard monitoring.

Reliable Guard Monitoring for Industrial Safety
Safety hinge switches such as the HPAA052C-3SN 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 and is 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.
