Why Choose the Pizzato HPAA050F-5SN Safety Hinge Switch?
The Pizzato HPAA050F-5SN is a heavy-duty 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, combining mechanical strength with 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 guarantee reliable disconnection even in fault conditions, making it ideal for safety-critical applications.
The HPAA050F-5SN features a 1 normally open (NO) and 2 normally closed (NC) contact configuration with a snap-action switching mechanism. It is supplied with a 5 metre oil-resistant PVC cable and operates with a 0° activation angle, providing consistent and accurate guard monitoring.

Reliable Guard Monitoring for Industrial Safety
Safety hinge switches such as the HPAA050F-5SN 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 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.
