Why Choose the Pizzato HPAA052M-5PN Safety Hinge Switch?
The Pizzato HPAA052M-5PN is a heavy-duty safety hinge switch designed for monitoring the position of hinged safety guards on industrial machinery. As part of the reliable Pizzato HP series, it integrates a safety switch directly into the hinge assembly, providing both mechanical support and precise guard position detection.
This design ensures that machinery operation is safely interrupted when access doors are opened, helping to protect operators and meet modern machine safety requirements. Its positive opening contacts and robust construction make it ideal for safety-critical environments.
Featuring a 2 normally open (NO) and 2 normally closed (NC) contact configuration, along with a slow-action switching mechanism, the HPAA052M-5PN is suitable for redundant safety circuits. This variant includes a 5 metre pre-wired cable, offering extended installation flexibility in larger machines and industrial systems.

Reliable Guard Monitoring for Industrial Safety
Safety hinge switches like the HPAA052M-5PN are designed to detect the opening and closing of protective guards. When a guard is opened, the switch interrupts the safety circuit, preventing hazardous machine operation and protecting personnel.
The HP series integrates the switching mechanism into the hinge itself, reducing tampering risk and simplifying installation. This design supports compliance with safety standards such as EN ISO 14119 for interlocking devices and industrial machinery safety.
Typical Applications
- Industrial machine guard monitoring.
- Access doors on automated production lines.
- Packaging and processing machinery.
- Machine tools and CNC equipment.
- Robotic cells and automated systems.
- OEM machine building and safety retrofits.
