Integration of safety switch in load-bearing hinge

Hinged machinery guards and covers as well as safety fence doors may be found in every type of industry.

Hinged machinery guards and covers as well as safety fence doors may be found in every type of industry. The Bernstein safety hinge switch SHS represents the consequential integration of a safety switch in a load-bearing hinge for industrial applications. Designed to facilitate mounting onto profiles and doors the slim profile of the SHS, even when fully closed, allows the hinge to be readily mounted where space is con-strained.

The operating angle is a full 180deg, the switching point can be set between 0deg and 180deg.

Traditional safety switches with separate actuator keys are often exposed to high de-grees of mechanical stress, in particular when mounted on the closing edge of guards where accumulated tolerances can cause misalignment.

The SHS hinge switch opens new doors with the safety contact mounted internally, inaccessible to the user and therefore providing excellent tamper protection.

2 SHS each with a forced disconnect safety contact allow safety category 4 systems to be configured subject to the required risk analysis and safety contact monitoring.

One or more SHS may be used dependent on the category of safety protection re-quired.

Matching hinges without safety contacts are also available, allowing the style to be standardised for general use.

Connectors as well as fixed cable versions with axial and radial (rear) mounting are available.
