HX BL22-15QN Pizzato Hinged-shaped safety switches in stainless steel HX series

Why Choose the Pizzato HX BL22-15QN Safety Hinge Switch?

The Pizzato HX BL22-15QN 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 BL22 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 opening of the relevant safety contacts as the associated guard moves, supporting dependable integration into industrial machine safety circuits.

Designed for demanding industrial environments, the HX BL22-15QN features corrosion-resistant AISI 316L stainless steel construction with the high ingress protection associated with the HX Series. This variant is supplied with a 15 m cable, providing extensive wiring reach for larger machines and installations where the safety hinge is positioned some distance from the safety control equipment.

Key Advantages

• Integrated safety hinge switch for machine guard monitoring.
• 2 NO + 2 NC contacts provide multiple channels for safety and auxiliary switching functions.
• Slow-action mechanical switching provides defined operation as the guard moves.

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, stainless steel construction and long 15 m connection cable, the HX BL22-15QN is well suited to demanding machinery where corrosion resistance and extended wiring reach are important.

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 or frequently cleaned environments.
• Large machines requiring extended safety switch cable runs.
