Schmersal Hinge Switch, NO/2NC, 230V AC - TESK Series - TESK-SU-12ST1

Protect machinery and personnel from hazardous situations using this safety hinge switch from Schmersal. It disconnects the power to active machine operations when it detects that a secured gate or hatch is open. It connects to the hinge pin of a medium-sized door and isolates machine power when the connected hinge is turned just 3°. This means it accurately detects when to activate for a precise and rapid response.
