Why Choose the Pizzato HX BL22-15PN Safety Hinge Switch?
The Pizzato HX BL22-15PN is a heavy-duty 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 BL22 contact configuration provides 2 NO + 2 NC slow-action contacts with positive-opening operation. Movement of the associated guard mechanically operates the internal contacts, allowing the machine safety circuit to detect guard opening while providing multiple contacts for safety-related and auxiliary control functions.
Designed for demanding environments, the HX BL22-15PN features a corrosion-resistant AISI 316L stainless steel housing with IP67 / IP69K protection. This variant has a rear cable output and is supplied with a 15 m, 9 × 0.34 mm² PVC cable. It is suitable for supply voltages from 24 V to 250 V AC/DC and has a standard 0° activation angle.
Key Advantages
- Integrated safety hinge switch for machine guard monitoring.
- 2 NO + 2 NC contacts provide multiple channels for safety and auxiliary switching functions.

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 directly into the hinge provides a compact and discreet alternative to conventional externally mounted safety switches. With its four-contact BL22 configuration, positive-opening operation, AISI 316L stainless steel construction and long 15 m connection cable, the HX BL22-15PN is well suited to demanding machinery where corrosion resistance, high ingress protection and extended wiring reach are required.
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.
- Large machines requiring extended safety switch cable runs.
