Why Choose the Pizzato HPAA050F-2SNH90 Safety Hinge Switch?
The Pizzato HPAA050F-2SNH90 is a heavy-duty safety hinge switch engineered 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, combining structural strength with accurate guard position detection.
This integrated design ensures machinery is automatically stopped when protective guards are opened, helping to safeguard operators and maintain compliance with modern machine safety standards. Its positive opening contacts provide dependable disconnection even in fault conditions, making it ideal for safety-critical applications.
The HPAA050F-2SNH90 features a 1 normally open (NO) and 2 normally closed (NC) contact configuration with a snap-action switching mechanism. It includes a 2 metre oil-resistant cable and a 90° activation angle, making it ideal for applications where wide-angle guard opening detection is required.

Reliable Guard Monitoring for Industrial Safety
Safety hinge switches such as the HPAA050F-2SNH90 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.
