Why Choose the Pizzato HX BL22-3SNH90 Stainless Steel Safety Hinge Switch?
The Pizzato HX BL22-3SNH90 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 BL22-3SNH90 uses the L22 mechanical contact block, providing 2NO + 2NC slow-action closer contacts with positive-opening safety operation. This four-contact configuration supports safety monitoring and auxiliary switching functions while providing direct mechanical actuation through movement of the hinged guard.
This version combines a 90° activation angle with a right-hand movable part and bottom cable outlet. Its AISI 316L stainless steel housing, 3 m oil-resistant PVC cable and IP67 / IP69K protection make it particularly suitable for hygienic, corrosive and demanding industrial machinery environments.
Key Advantages
- Integrated safety hinge and guard-monitoring switch in one compact assembly.
- 2NO + 2NC slow-action contacts support safety and auxiliary switching functions.

Reliable Mechanical Safety Monitoring for Hinged Guards
The Pizzato HX Series incorporates the electrical safety switching mechanism directly into the mechanical hinge. Movement of the hinged machine guard therefore actuates the internal contacts without requiring a separate key or external actuator, providing a compact installation with fewer exposed guard-monitoring components.
The HX BL22-3SNH90 combines an L22 slow-action 2NO + 2NC contact block with positive-opening operation and a 90° activation angle. Its right-hand movable part, bottom cable outlet and pre-wired 3 m cable provide a defined configuration for machine builders integrating safety monitoring into hinged guards and access doors.
