HX BL22-1PNH15 Pizzato Hinged-shaped safety switches in stainless steel HX series

Why Choose the Pizzato HX BL22-1PNH15 Stainless Steel Safety Hinge Switch?

The Pizzato HX BL22-1PNH15 is a heavy-duty stainless steel safety hinge switch designed for monitoring hinged guards, doors and protective access panels on industrial machinery. As part of the Pizzato HX series, it combines the mechanical hinge and safety switching functions within a robust assembly, providing reliable guard-position monitoring without a conventional separate actuator.

The HX series uses an AISI 316L stainless steel housing, making it particularly suitable for demanding industrial environments where corrosion resistance, hygiene and mechanical durability are important. The BL22 configuration incorporates 2NO + 2NC slow-action contacts with positive-opening operation for safety-related guard monitoring.

The HX BL22-1PNH15 is a cabled configuration with the connection routed from the rear of the hinge assembly. Its HX series construction provides IP67 protection according to EN 60529 and IP69K protection according to ISO 20653, supporting use in environments exposed to dust, water and intensive cleaning.

Key Advantages

• Combines a machine hinge and safety switch in one integrated component.
• Robust AISI 316L stainless steel housing provides excellent corrosion resistance.
• 2NO + 2NC slow-action contacts provide safety and signalling functionality.
• Positive-opening operation supports dependable safety-related guard monitoring.
• Integrated hinge design eliminates the need for a conventional separate actuator.
• High environmental protection with IP67 and IP69K ratings.
• Suitable for demanding industrial and hygiene-sensitive machine environments.

Robust Stainless Steel Guard Monitoring

Safety hinge switches monitor movable guards by integrating the safety switching mechanism directly into the mechanical hinge. As the guard opens, rotation of the hinge operates the contacts, allowing the machine safety system to detect that the protective guard has moved away from its safe position without requiring an exposed separate actuator.

The Pizzato HX series is particularly suited to demanding applications because its AISI 316L stainless steel construction combines mechanical durability with excellent corrosion resistance. Positive-opening contacts and high IP67/IP69K environmental protection make the HX BL22-1PNH15 a practical solution for industrial machinery where dependable guard monitoring and resistance to challenging operating conditions are required.

Typical Applications
