Why Choose the Pizzato HP AA052D-KSMH45 Safety Hinge Switch?
The Pizzato HP AA052D-KSMH45 is a robust safety hinge switch designed for reliable monitoring of hinged machine guards, safety doors and access panels. As part of the Pizzato HP Series safety hinge switches, it combines the mechanical hinge and electromechanical safety switching function into a single compact device, eliminating the need for a separate external safety switch actuator.
The HP AA052D-KSMH45 features a 2 NC slow-action contact configuration with positive-opening safety operation. As the hinged guard opens, rotation of the hinge mechanically operates the safety contacts, allowing the connected safety control system to detect access and initiate the appropriate safe stopping function.
This variant features an approximately 45° activation angle and an M12 5-pole connector for convenient connection to industrial safety circuits. Its durable metal construction and IP67 / IP69K protection make the HP AA052D-KSMH45 well suited to demanding machine-building, manufacturing and automation environments.

Reliable Safety Monitoring for Industrial Machine Guards
Safety hinge switches such as the Pizzato HP AA052D-KSMH45 integrate electrical guard monitoring directly into the hinge of a machine door or protective enclosure. As the guard opens and reaches the switching angle, the hinge mechanism operates the internal safety contacts so that the machine safety control system can detect access to the protected area.
The HP Series is designed for machine builders and industrial automation engineers requiring compact, robust and dependable guard-monitoring components. Positive-opening contacts provide direct mechanical separation of the safety circuit, while the M12 connector and hinge-integrated construction simplify installation into modern machine guarding systems.
Typical Applications
- Hinged machine guards and safety doors.
- Industrial production and assembly machinery.
- Automated manufacturing and robotic cells.
- Packaging and processing equipment.
- Conveyor and material handling systems.
- Machine enclosures and protected access panels.
