Why Choose the Pizzato HPAA050M-4AN Safety Hinge Switch?
The Pizzato HPAA050M-4AN is a heavy-duty safety hinge switch designed for monitoring hinged guards and access doors in industrial machinery. As part of the robust Pizzato HP Series, it integrates the switching mechanism directly into the hinge, eliminating the need for external actuators and delivering a compact, tamper-resistant safety solution.
Constructed with a rugged metal housing, this hinge switch is engineered for long-term reliability in demanding industrial environments. It ensures machinery operates only when guards are securely closed, helping maintain compliance with machinery safety standards and protecting operators.
This model features 2 NO + 2 NC snap-action contacts, a 4 metre oil-resistant PVC cable, and a 0° activation angle, providing immediate switching response and enhanced redundancy for safety-critical applications.

Immediate Safety Response with Redundant Contacts
The HPAA050M-4AN delivers instant switching thanks to its 0° activation angle, meaning the safety circuit reacts immediately when the guard begins to open. This rapid response helps prevent hazardous machine movement and enhances operator safety.
Its dual NO and dual NC contact configuration enables redundant safety circuits and improved fault detection, making it suitable for higher safety integrity applications. By integrating the switch into the hinge, it removes alignment issues and reduces tampering risks associated with traditional actuator-based safety switches.
