Why Choose the Pizzato HPAA050M-10SN Safety Hinge Switch?
The Pizzato HPAA050M-10SN is a high-performance safety hinge switch designed for monitoring hinged safety guards on industrial machinery. Part of the heavy-duty Pizzato HP series, it integrates the switching mechanism directly into the hinge, combining structural durability with precise guard position detection.
This integrated 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 guarantee safe disconnection even in fault conditions, making it suitable for critical safety applications.
The HPAA050M-10SN features a 2 normally open (NO) and 2 normally closed (NC) contact configuration with a snap-action switching mechanism. It is supplied with a 10 metre oil-resistant PVC cable, offering extended installation flexibility for large machines and complex layouts.

Reliable Guard Monitoring for Industrial Safety
Safety hinge switches such as the HPAA050M-10SN 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 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.
