Why Choose the Pizzato HPAA052F-1AN Safety Hinge Switch?
The Pizzato HPAA052F-1AN is a compact and high-performance safety hinge switch designed for monitoring hinged guards and access doors in industrial machinery. As part of the reliable Pizzato HP Series, it integrates the switching mechanism directly into the hinge, eliminating the need for external actuators and providing a tamper-resistant, space-saving safety solution.
Constructed with a robust metal housing, this hinge switch ensures dependable operation in demanding industrial environments. It helps prevent machine operation when guards are open, supporting compliance with machinery safety standards and protecting personnel.
This model features 1 NO + 2 NC slow-action contacts, a 1 metre oil-resistant PVC cable, and a 0° activation angle, delivering immediate switching response and enhanced redundancy for safety-critical applications.
