Why Choose the Pizzato HPAA050F-1SN Safety Hinge Switch?
The Pizzato HPAA050F-1SN is a compact and highly reliable safety hinge switch designed for monitoring hinged guards on industrial machinery. As part of the durable Pizzato HP series, it integrates the switching mechanism directly into the hinge, combining mechanical strength with accurate guard position detection.
This integrated design ensures that 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 dependable disconnection even under fault conditions.
The HPAA050F-1SN features a 1 normally open (NO) and 2 normally closed (NC) contact configuration with a snap-action switching mechanism. It includes a 1 metre oil-resistant PVC cable and a 0° activation angle, providing precise and consistent guard monitoring in compact installations.

Reliable Guard Monitoring for Industrial Safety
Safety hinge switches such as the HPAA050F-1SN 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. Pizzato HP series 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.
