Pizzato HPAA050M-4AN safety hinge switch with metal housing, 2 NO + 2 NC snap-action contacts, 4 m cable and 0 degree activation angle for industrial safety applications.
£63.37
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.
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.

This safety hinge switch monitors hinged guards and doors to ensure machinery only operates when guards are closed.
The device includes 2 normally open (NO) and 2 normally closed (NC) contacts, enabling advanced safety circuit design.
The switch operates with a 0° activation angle, providing immediate response when the guard starts to move.
This version is supplied with a 4 metre pre-wired cable for flexible installation.
Multi-contact designs allow redundant safety circuits and improved fault detection, increasing overall machine safety.
Pizzato HP Series hinge switches are widely trusted by machine builders and automation engineers for reliable guard monitoring, durable construction and consistent safety performance in demanding industrial environments.
