Why Choose the Pizzato HPAA050M-3SN Safety Hinge Switch?
The Pizzato HPAA050M-3SN 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, delivering both mechanical durability and precise guard position detection.
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 dependable disconnection even in fault conditions, making it suitable for critical safety applications.
The HPAA050M-3SN features a 2 normally open (NO) and 2 normally closed (NC) contact configuration with a snap-action switching mechanism. It is supplied with a 3 metre oil-resistant PVC cable and operates with a 0° activation angle, ensuring precise and consistent guard monitoring.

Reliable Guard Monitoring for Industrial Safety
Safety hinge switches such as the HPAA050M-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. 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.
