Why Choose the Pizzato HX BL22-3PN Stainless Steel Safety Hinge Switch?
The Pizzato HX BL22-3PN is a 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 BL22 configuration belongs to the mechanical switching range of HX safety hinges and provides 2NO + 2NC slow-action contacts with positive-opening safety operation. This four-contact arrangement provides flexibility for safety monitoring and auxiliary machine-control functions while maintaining direct mechanical actuation through movement of the guard.
The HX BL22-3PN combines robust AISI 316L stainless steel construction with a 3 m pre-wired cable and rear connection arrangement. The stainless steel HX design is particularly suited to applications where hygiene, corrosion resistance and a compact integrated guard-monitoring solution are important.
Key Advantages
- Combines the mechanical hinge and safety switch in one compact assembly.
- 2NO + 2NC slow-action contacts support safety and auxiliary switching functions.
- Positive-opening operation provides direct mechanical opening of the safety contacts.
- Integrated design eliminates the need for a conventional separate safety-switch actuator.
- Robust AISI 316L stainless steel construction for demanding environments.
- 3 m pre-wired cable simplifies connection to the machine wiring system.
- Rear cable outlet supports discreet cable routing through the machine structure.
- Suitable for hygienic, corrosion-prone and demanding industrial machinery.

Integrated Mechanical Safety Monitoring for Hinged Guards
The Pizzato HX Series incorporates the safety switching mechanism directly into the mechanical hinge. Opening or closing the hinged machine guard therefore actuates the internal contacts without requiring a separate key or external actuator, providing a clean and compact solution for safety-door monitoring.
The BL22 mechanical configuration combines 2NO + 2NC slow-action contacts with positive-opening operation. Together with the stainless steel construction and rear-output 3 m cable, the HX BL22-3PN provides a practical solution for machine builders requiring integrated guard monitoring in demanding industrial installations.
