Type SHS

The safety hinge switch SHS is the logical integration of the safety switch and load-bearing hinge for industrial applications.
IP 67 Metal housing
Safe:
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.
Flexible:
- 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.
Fast:
Connectors as well as fixed cable versions with axial and radial (rear) mounting are available.
Reliable:
- 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.
