"The SI-HG80 series is unique as the safety switch has been designed and integrated into a load bearing hinge body. This helps provide a high degree of protection against intentional defeat and mechanical impact reducing accidents, wear and tear and cutting maintenance costs. The hinge operates in a full 180° range and the switching point is adjustable over the full 180° operating range.Typical Applications:. Hinged covers and guards to machines. Hinged doors and gates in safety fencing systems. Modular aluminium framingMaterial: Zinc die-cast. Contact rating: 3.0A at 250 Vac, 0.5A at 60 Vdc. Operating range: 0° to 180°.
