HX BH22-5QNH90 Pizzato Hinged-shaped safety switches in stainless steel HX series

Why Choose the Pizzato HX BH22-5QNH90 Safety Hinge Switch?

The Pizzato HX BH22-5QNH90 is a heavy-duty stainless steel safety hinge switch from the Pizzato HX Series, designed for monitoring hinged machine guards, protective doors and access panels. By combining the mechanical hinge and safety switching functions within a single assembly, the HX Series provides discreet guard monitoring without requiring a separate external safety switch and actuator.

The BH22 contact configuration provides 2 NO + 2 NC slow-action contacts for safety-related guard monitoring and auxiliary control functions. Positive-opening operation provides direct mechanical actuation of the safety contacts as the associated guard moves, supporting dependable integration into industrial machine safety circuits.

Designed for demanding industrial environments, the HX BH22-5QNH90 uses corrosion-resistant AISI 316L stainless steel construction and the HX Series provides IP67 / IP69K protection. This variant incorporates a 5 m cable connection, while its H90 hinge configuration provides a specific mechanical orientation for installations requiring this HX Series arrangement.

Reliable Guard Monitoring for Industrial Machinery

Mechanical safety hinge switches such as the Pizzato HX Series combine the structural function of a hinge with safety-related position monitoring. Opening the associated guard mechanically operates the internal contacts, allowing the connected safety circuit to detect movement of the protective door or guard from its intended safe position.

Integrating the switching mechanism directly into the hinge provides a compact and discreet alternative to conventional externally mounted safety switches. With its four-contact BH22 configuration, positive-opening operation and corrosion-resistant stainless steel construction, the HX BH22-5QNH90 is well suited to machinery requiring durable guard monitoring in demanding industrial environments.

Typical Applications

• Hinged machine guards and protective doors.
• Food and beverage production machinery.
• Packaging and processing equipment.
• Industrial automation and manufacturing systems.
• Machinery operating in demanding washdown environments.
• Equipment requiring corrosion-resistant stainless steel safety components.
