HX BH22-0.2PMH90 Pizzato Hinged-shaped safety switches in stainless steel HX series

Why Choose the Pizzato HX BH22-0.2PMH90 Safety Hinge Switch?

The Pizzato HX BH22-0.2PMH90 is a robust 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 in one assembly, it provides discreet guard position monitoring without requiring a separate external safety switch and actuator.

The HX Series BH22 configuration uses 2 NO + 2 NC slow-action contacts with positive-opening operation for safety-related guard monitoring. The integrated mechanical switching arrangement allows movement of the hinged guard to operate the safety contacts directly, supporting dependable integration into industrial machine safety circuits.

Designed for demanding environments, the HX BH22-0.2PMH90 uses a corrosion-resistant AISI 316L stainless steel housing and provides IP67 / IP69K protection. This variant incorporates a short 0.2 m connection cable and M12 connection arrangement, combining straightforward machine wiring with the durability and washdown resistance associated with the Pizzato HX stainless steel range.

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 a connected safety circuit to detect movement of the protective door or guard from its intended safe position.

Integrating the switching mechanism into the hinge provides a compact and discreet alternative to conventional externally mounted safety switches. With its four-contact BH22 configuration, positive-opening operation, AISI 316L stainless steel construction and high ingress protection, the HX BH22-0.2PMH90 is particularly well suited to machinery operating in demanding industrial and washdown 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.
