HX BL22-3ANH90 Pizzato Hinged-shaped safety switches in stainless steel HX series

Why Choose the Pizzato HX BL22-3ANH90 Safety Hinge Switch?

The Pizzato HX BL22-3ANH90 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 hinge and safety switching functions within 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. The contacts use a slow-action close switching arrangement, allowing movement of the hinged guard to mechanically operate the safety contacts and provide dependable position monitoring within industrial machine safety circuits.

Designed for demanding environments, the HX BL22-3ANH90 features an AISI 316L stainless steel housing with IP67 / IP69K protection. This variant has the movable hinge part on the right, a top cable output, an oil-resistant 3 m PVC cable and a 90° activation angle, making it suitable for installations requiring this specific guard geometry and cable routing arrangement.

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 positive-opening operation supports safety-related guard monitoring.

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 or closing the associated guard mechanically operates the internal contacts, allowing a connected safety circuit to detect movement of the protective door or guard relative to 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, 90° activation angle, AISI 316L stainless steel construction and high ingress protection, the HX BL22-3ANH90 is well suited to demanding machinery where corrosion resistance and defined guard activation geometry 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.
• Guarding applications requiring a 90° activation angle and top cable routing.
