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

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

The Pizzato HX BH22-5SN 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 integrating the mechanical hinge and safety switching functions into a single assembly, it provides discreet guard position 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 BH22-5SN features corrosion-resistant AISI 316L stainless steel construction with IP67 / IP69K protection. This version is supplied with a 5 m cable and bottom cable output, providing useful wiring reach while maintaining a compact installation around the hinged guard.

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, stainless steel construction and high ingress protection, the HX BH22-5SN is well suited to machinery requiring dependable guard monitoring in harsh, corrosive or frequently cleaned 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.
