HP AA052F-2SNH15 Pizzato Safety hinge switch

Why Choose the Pizzato HP AA052F-2SNH15 Safety Hinge Switch?

The Pizzato HP AA052F-2SNH15 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 integrates the electromechanical safety switch directly into the mechanical hinge, providing effective guard position monitoring while eliminating the need for a separate external actuator.

The HP AA052F-2SNH15 features a 1 NO + 2 NC slow-action 52F contact block with positive opening of the safety contacts. When the hinged guard is opened, rotation of the hinge mechanically operates the contacts, allowing the connected machine safety system to detect access and initiate the appropriate safe stopping function.

This H15 variant has a 15° activation angle and is equipped with an integrated 2 m PVC cable with 7 × 0.5 mm² conductors and a bottom cable exit. Its durable metal housing, approximately 100 × 45 mm movable part and IP67 / IP69K protection make the HP AA052F-2SNH15 suitable for demanding industrial machinery and automation environments.

Reliable Safety Monitoring for Industrial Machine Guards

Safety hinge switches such as the Pizzato HP AA052F-2SNH15 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 applications where compact installation, robust construction and dependable safety switching are required. The 15° base activation angle can suit applications requiring the safety contacts to change state after a defined degree of guard movement, while the positive-opening mechanism provides direct mechanical operation of the safety contacts.

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.
