Why Choose the Pizzato HPAA050F-6SN Safety Hinge Switch?
The Pizzato HPAA050F-6SN is a heavy-duty safety hinge switch designed for reliable monitoring of hinged safety guards on industrial machinery. As part of the durable Pizzato HP series, it integrates the switching mechanism directly into the hinge, delivering both mechanical robustness and precise guard position detection.
This integrated design 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 ensure safe disconnection even in fault conditions, making it ideal for safety-critical environments.
The HPAA050F-6SN features a 1 normally open (NO) and 2 normally closed (NC) contact configuration with a snap-action switching mechanism. It includes a 6 metre oil-resistant PVC cable and operates with a 0° activation angle, ensuring accurate and reliable guard monitoring.

Reliable Guard Monitoring for Industrial Safety
Safety hinge switches such as the HPAA050F-6SN 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 widely used for safety interlocking in accordance with EN ISO 14119 standards for 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.
