Why Choose the Pizzato HPAA052M-20AN Safety Hinge Switch?
The Pizzato HPAA052M-20AN is a high-capacity safety hinge switch designed for monitoring hinged guards and access doors in industrial machinery. As part of the heavy-duty Pizzato HP Series, it integrates the switching mechanism directly into the hinge, eliminating external actuators and delivering a compact, tamper-resistant safety solution.
Engineered with a rugged metal housing, this hinge switch ensures reliable performance in demanding industrial environments. It prevents machine operation when guards are open, supporting compliance with machinery safety standards and protecting personnel.
This model features 2 NO + 2 NC slow-action contacts, a 20 metre oil-resistant PVC cable, and a 0° activation angle, providing immediate switching response and maximum flexibility for complex and redundant safety circuits.
