Why Choose the Pizzato HX BH22-0.2PMH75 Safety Hinge Switch?
The Pizzato HX BH22-0.2PMH75 is a robust stainless steel safety hinge switch from the Pizzato HX Series, designed for monitoring hinged guards, protective doors and access panels on industrial machinery. By integrating the safety switching mechanism directly into the hinge assembly, the HX Series provides discreet guard monitoring without the need for a separate external safety switch and actuator.
The BH22 configuration provides 2 NO + 2 NC slow-action contacts with make-before-break switching and positive-opening operation. The switching point can be adjusted to suit the guard installation, allowing the hinge switch to be configured for reliable detection of guard movement in safety-related machinery applications.
Manufactured with an AISI 316L stainless steel housing, the HX BH22-0.2PMH75 provides IP67 protection according to EN 60529 and IP69K protection according to ISO 20653. Electrical connection is provided through a 0.2 m PVC cable with an 8-pole M12 connector routed from the rear of the hinge assembly, while the switching contacts are suitable for supply voltages from 24 V to 250 V AC/DC.

Reliable Guard Monitoring for Industrial Machinery
Mechanical safety hinge switches such as the Pizzato HX BH22 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 into the hinge provides a compact and discreet alternative to conventional externally mounted safety switches. With its four-contact BH22 configuration, positive-opening operation, AISI 316L stainless steel construction and high ingress protection, the HX BH22-0.2PMH75 is well suited to machinery operating in demanding industrial, hygienic and washdown environments.
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.
- Equipment requiring corrosion-resistant stainless steel safety components.
