Why Choose the Pizzato HPAA052F-1PNH45 Safety Hinge Switch?
The Pizzato HPAA052F-1PNH45 is a precision-engineered safety hinge switch designed for monitoring hinged safety guards in industrial machinery. As part of the robust Pizzato HP series, it integrates the switching mechanism directly into the hinge, ensuring reliable machine shutdown when a guard is opened.
Built with a durable metal housing, this switch delivers consistent performance in demanding industrial environments. Its integrated hinge construction eliminates the need for external actuators, simplifying installation while maintaining precise 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 1 metre oil-resistant PVC cable and a defined 45° activation angle, making it ideal for applications requiring controlled switching at a specific guard opening position.
