HP AB052D-5QN Pizzato Safety hinge switch

Why Choose the Pizzato HP AB052D-5QN Safety Hinge Switch?

The Pizzato HP AB052D-5QN is a robust safety hinge switch designed for reliable monitoring of hinged machine guards, safety doors and protective access panels. Part of the Pizzato HP Series, it combines the mechanical hinge and electrical safety switching functions within a compact metal assembly, providing an integrated and discreet solution for industrial machine guarding.

This safety hinge switch features a 2 NC contact configuration using the 52D contact block, providing slow-action switching with positive opening of the safety contacts. Positive opening ensures direct mechanical separation of the normally closed contacts as the guard moves, supporting dependable position monitoring within safety-related machine control systems.

The HP AB052D-5QN is supplied with a 5 m oil-resistant PVC cable compliant with IEC 60332-1-2. It features a left-hand movable part with rear cable output, a 100 × 75 mm movable part and a standard 0° activation angle. Its metal construction and IP67 / IP69K protection make it suitable for demanding industrial environments.

Reliable Guard Monitoring for Industrial Machinery

Safety hinge switches such as the Pizzato HP AB052D-5QN combine the mechanical function of a hinge with an integrated electrical safety switching mechanism. As a hinged guard or safety door moves from its protected position, the slow-action contacts change state so that the machine safety system can detect guard movement and initiate the required protective response.

Integrating the safety switch directly into the hinge provides a compact and discreet alternative to conventional guard switches with separate actuators. The HP AB052D-5QN combines dual normally closed contacts, positive opening safety operation, robust metal construction and a pre-wired 5 m cable for dependable integration into industrial machine guarding systems.

Typical Applications

• Hinged safety guards on industrial machinery.
• Machine access doors and protective panels.
• Packaging and production machinery.
• Automated manufacturing cells.
• Assembly and processing equipment.
• Material handling and conveyor systems.
• OEM machine building and industrial safety systems.
