Why Choose the Pizzato HX BL22-2PNH15 Safety Hinge Switch?
The Pizzato HX BL22-2PNH15 is a robust stainless-steel safety hinge switch designed for monitoring hinged machine guards, safety doors and protective access panels. Part of the Pizzato HX Series, it integrates the mechanical hinge and safety switching functions into a single compact assembly, providing reliable guard-position monitoring without requiring a conventional separate actuator.
The HX BL22-2PNH15 features an L22 contact block with 2 NO + 2 NC contacts and slow-action mechanical switching with positive-opening safety operation. This configuration enables dependable detection of guard movement and makes the switch suitable for integration into safety-related machine control and interlocking circuits.
Manufactured from corrosion-resistant AISI 316L stainless steel, the HX BL22-2PNH15 is designed for demanding industrial installations. The 2PN version incorporates a 2 m PVC cable with rear cable output, while the H15 suffix identifies the specified hinge activation-angle configuration for this variant. High IP67 / IP69K protection further supports installation where resistance to dust, water and intensive cleaning is required.

Reliable Stainless-Steel Guard Monitoring for Industrial Machinery
Safety hinge switches integrate guard-position detection directly into the hinge of a protective door or panel. Rotation of the guard mechanically actuates the internal contacts, allowing the connected machine safety system to detect opening of the protective device and initiate the required safety response.
The Pizzato HX Series combines this integrated operating principle with AISI 316L stainless-steel construction, positive-opening contacts and high environmental protection. This makes the HX BL22-2PNH15 particularly suitable for machinery where corrosion resistance, compact installation and dependable mechanical guard monitoring are important.
Typical Applications
- Hinged machine guards and safety doors.
- Food and beverage processing machinery.
- Packaging and production equipment.
- Pharmaceutical and process machinery.
- Industrial automation systems.
- Robot cell access panels and protective enclosures.
- OEM machinery requiring corrosion-resistant safety components.
