Why Choose the Pizzato HPAA052F-5PNH90 Safety Hinge Switch?
The Pizzato HPAA052F-5PNH90 is a heavy-duty safety hinge switch designed for precise monitoring of hinged safety guards in industrial machinery. As part of the advanced Pizzato HP series, it integrates the switching mechanism directly into the hinge, ensuring dependable machine shutdown when a guard is opened.
Manufactured with a rugged metal housing, this switch is engineered for durability and consistent operation in demanding industrial environments. Its integrated hinge design eliminates the need for external actuators, simplifying installation while ensuring accurate alignment and long-term reliability.
This model features a 1NO + 2NC contact configuration with positive opening operation and a slow-action switching mechanism. It includes a 5 metre oil-resistant PVC cable and a defined 90° activation angle, making it ideal for applications requiring delayed switching at wide guard opening positions.
