Why Choose the Pizzato HPAA052F-20AN Safety Hinge Switch?
The Pizzato HPAA052F-20AN is a heavy-duty safety hinge switch engineered 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.
Built with a durable metal housing, this hinge switch ensures reliable operation in demanding industrial environments. It prevents machine operation when guards are open, helping maintain compliance with machinery safety standards and protecting operators.
This model features 1 NO + 2 NC slow-action contacts, a 20 metre oil-resistant PVC cable, and a 0° activation angle, providing immediate switching response and enhanced redundancy for safety-critical applications.
Key Advantages
- Integrated safety hinge design eliminates actuator alignment issues.
- 1 NO + 2 NC contact configuration enables redundant safety circuits.
- Slow-action switching ensures stable and controlled performance.
- 20 m pre-wired cable ideal for large machinery and extended installations.
- Metal housing construction ensures durability in industrial environments.
- Oil-resistant cable suitable for harsh industrial conditions.
