Why Choose the Pizzato HPAA050C-3SN Safety Hinge Switch?
The Pizzato HPAA050C-3SN is a robust safety hinge switch designed 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, combining structural strength with precise guard position detection.
This integrated design ensures that machinery is safely stopped when protective guards are opened, helping protect operators and maintain compliance with modern machine safety standards. Its positive opening contacts ensure reliable disconnection even in fault conditions, making it ideal for safety-critical applications.
The HPAA050C-3SN features a 1 normally open (NO) and 1 normally closed (NC) contact configuration with a snap-action switching mechanism. It is supplied with a 3 metre pre-wired cable, offering flexibility for installation across a wide range of industrial applications.

Reliable Guard Monitoring for Industrial Safety
Safety hinge switches such as the HPAA050C-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 function directly into the hinge, this design reduces tampering risk and simplifies installation. These devices 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.
