Why Choose the Pizzato HPAA050M-0.5SN Safety Hinge Switch?
The Pizzato HPAA050M-0.5SN is a high-performance safety hinge switch designed for monitoring hinged safety guards on industrial machinery. Part of the advanced Pizzato HP series, it integrates the switching mechanism directly into the hinge, providing both structural strength and precise guard position detection.
This integrated safety solution 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 ensure reliable disconnection even in fault conditions, making it suitable for critical safety applications.
The HPAA050M-0.5SN features a 2 normally open (NO) and 2 normally closed (NC) contact configuration with a snap-action switching mechanism. It includes a 0.5 metre oil-resistant PVC cable and operates with a 0° activation angle, delivering highly precise guard monitoring in compact installations.

- Silver contacts for reliable electrical performance.
- High ingress protection (IP67 / IP69K typical for series).
Reliable Guard Monitoring for Industrial Safety
Safety hinge switches such as the HPAA050M-0.5SN 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 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.
