Why Choose the Pizzato HX BH22-5PNH90 Stainless Steel Safety Hinge Switch?
The Pizzato HX BH22-5PNH90 is a robust stainless steel safety hinge switch designed for monitoring hinged guards and safety doors on industrial machinery. Part of the Pizzato HX Series, it integrates the mechanical hinge and electrical safety switching functions into a single assembly, providing discreet guard monitoring without requiring a conventional separate actuator.
The HX BH22-5PNH90 uses the H22 mechanical contact block, providing 2NO + 2NC slow-action contacts with make-before-break operation. Positive-opening operation of the safety contacts provides direct mechanical actuation, while the four-contact arrangement supports both safety monitoring and auxiliary signalling or control functions.
This H90 version is configured with a 90° base activation angle. It combines an AISI 316L stainless steel housing with a 5 m PVC cable and rear cable outlet, providing a durable solution for hinged guards in hygienic, corrosion-prone and demanding industrial environments.

Reliable Mechanical Safety Monitoring for Hinged Guards
The Pizzato HX Series incorporates the safety switching mechanism directly into the hinge, allowing movement of a machine guard to actuate the electrical contacts without a separate key or external actuator. This integrated arrangement provides a compact installation and helps reduce exposed components around the guarded opening.
The H90 configuration provides a 90° base activation angle for applications requiring the hinge switching function to be referenced around this angular position. Combined with the H22 slow-action contact block and positive-opening operation, the HX BH22-5PNH90 provides dependable mechanical guard monitoring for industrial machinery.
