Safety-Hinge Switch, Type SHS - BERNSTEIN AG - #1

IP 67 Metal housing

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

Designed to facilitate mounting onto extruded aluminium profiles, steel or plastic doors, the slim profile of the SHS even when fully closed, allows the hinge to be readily mounted where space is constrained.

Traditional safety switches with separate actuator keys are often subject to mechani­cal wear, particularly when mounted on the closing edge of guards where accumulated tolerances can cause misalignment. The SHS removes this problem with the safety contact mounted internally, inaccessible to the user and therefore providing excellent tamper protection. One or more switches may be used dependent on the category of safety protection required. Matching hinges without safety contacts are also available, allowing the style to be standardised for general use. In operation, consideration must simply be given to the required con­tact operation angle, which is determined by guard size and the maximum allowable guard opening distance before actuation.

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

• The hinge operating angle is 0-180°.

• The switch point may similarly be select­ed through 180°.

• AC/DC to 250 V or 60 V DC versions available.

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

• A cast Zinc alloy body allows the SHS a high degree of mounting freedom.

• In it's hinge capacity the SHS can bear up to 750 N axially and 1000 N radially, after the switching point has been set.

• Ingress protection to IP 67.
